Not working for me for iOS 8 as well. It gives too many errors. Is there anyone that corrects errors in the classes?
Note: I do not use automatic reference counting on objective c

Hi there

I am developing an app where the username/password should be encrypted on android device and decrypted on .net web service. The issue is that some time I'm getting the plus '+' sign in the encrypted string which leads to error. Is that normal ? how to get rid of it without breaking the app ? I'm using the same public key and IV on app and server.

Thanks.

You've commented that the secure random is broken on many platforms - how about including the fix in the IV generation code?

13 th Character of Decrypted text differ from plain Text when decrypt the same Encrypted text in C# 13 to 17 character get changed , How can I fix This

Same Key and IV used in the three Platforms java,Objective C and C#

Hi,

Thank you for your great lib, I used this with android client and asp.net server,but I am unable to decrypt message in the server. I use the method

CryptLib.SHA256("16 characters", 32);

when I decrypt in the server, please help me to check.
thanks

How I get the value of the IV? Simple concatenation?
I'm referring about this step -> "Get the encrypted text and the randomIV used for encryption"
Then, I'm very glad if you post an example 👍

Is anyone test with crypto-js ? I can not handle within.

// My testing string is "This is test Encryption String Two"

NSString *str=[[NSBundle mainBundle] pathForResource:@"data" ofType:@"rtf"];
NSData *data = [NSData dataWithContentsOfFile:str];

NSString *iv = @"VFSGlobalApp";
NSString *key = [[CryptLib alloc]sha256:@"VFSGlobalApp" length:31];//getHashSha256(@"VFSGlobalApp", 31); //32 bytes

Hello,

As per the code I need to Decrypt the Android Encrypted string in C# we have the exception called
"Padding is invalid and cannot be removed."

For android

        CryptLib _crypt = new CryptLib();
        String output = "";
        String plainText = "Madhav";
        String key = CryptLib.SHA256("Test", 32); // 32 bytes = 256
        String iv = CryptLib.generateRandomIV(16); // 16 bytes = 128 bit
        output = _crypt.encrypt(plainText, key, iv); // encrypt
        System.out.println("encrypted text=" + output);

For c#

        CryptLib _crypt = new CryptLib ();
        String iv = CryptLib.GenerateRandomIV (16); //16 bytes = 128 bits
        string key = CryptLib.getHashSha256("Test", 32); //32 bytes = 256 bits
        Console.WriteLine ("Plain text =" + _crypt.decrypt ("Android Encryption String", key, iv));

"Android Encryption String" = Encrypted string from Android Code , as above.

Now i have tried with reverse Like i need to decrypt C# encrypted string in Android , it also give me exception called.
"javax.crypto.BadPaddingException: EVP_CipherFinal_ex"

For C#

        CryptLib _crypt = new CryptLib ();
        string plainText = "Madhav";
        String iv = CryptLib.GenerateRandomIV (16); //16 bytes = 128 bits
        string key = CryptLib.getHashSha256("Test", 31); //32 bytes = 256 bits
        String cypherText = _crypt.encrypt (plainText, key, iv);
        Console.WriteLine ("iv="+iv);
        Console.WriteLine ("key=" + key);
        Console.WriteLine("Cypher text=" + cypherText);

For android

        CryptLib _crypt = new CryptLib();
        String output = "";
        String key = CryptLib.SHA256("Test", 32); // 32 bytes = 256
        String iv = CryptLib.generateRandomIV(16); // 16 bytes = 128 bit
        output = _crypt.decrypt("C# Encryption String", key, iv); // decrypt

"C# Encryption String" = Encrypted string from C# Code , as above.

Can you please check this if i have done anything wrong , can you please guide me for that ,
that will be appreciable.

Thanks in Advance
Madhav

I wonder where I can find the StringEncryption.h and the NSData+Base64.h, thank you very much.

In iOS, generateRandomIV() returns NSData, not NSString. So I tried some ways to convert the NSData to NSString but fail.

I'm using Swift 2.x with Objc Bridge Headers to include CryptLib.m/h and NSData+Base64.m/h. Here's the code:

Method 1

let data = aes256encrypter.generateRandomIV(16)
let iv = data.base64EncodedStringWithOptions(.EncodingEndLineWithCarriageReturn)
print(iv)

It prints out something like Zo8sin4RHrj77WWc5LV3xw==, which is not the length I want

Method 2

let data = aes256encrypter.generateRandomIV(16)
let iv = String(data: data, encoding: NSUTF8StringEncoding) 

It becomes nil now.

So how to get a random IV in iOS? It's really easy to generate random IV in java using the same API. Why isn't generateRandomIV() in iOS returns a NSString instead of NSData?

Hi there,

I try to use your library classes to encrypt and decrypt some strings that are shared between apps.
I'm using C# to create a Hybrid app with one code base for iOS and Android.
So the encryption is done in C#.
That's working fine that way:

CryptLib crypto = new CryptLib();
string iv = CryptLib.GenerateRandomIV (16); //Hash of 128 bits
string key = CryptLib.getHashSha256 (KEY,32); //256 bits
string encryptedText= crypto.encrypt (textToEncrypt, key, iv);

After that I cut the encrypted text into half and put the iv in. On that way I'm able to read the used iv from other apps that share the value with the encrypting app.

In Android, that's working pretty fine that way:

//The key of the encryption
String key = "MYKEYUSEDBEFORE";
//Cut out the iv that was used in encryption
int end = encryptedText.length()/2+8;
int start = end-16;
String iv = encryptedText.substring(start,end);
//Remove the iv from the encryptedText
encryptedText = encryptedText.replace(iv, "");
try
 {
    //decrypt and return the decryptedText
    key = CryptLib.SHA256(key, 32);
    CryptLib crypto = new CryptLib();
    String result = crypto.decrypt(encryptedText, key, iv);
    return result;
}
catch(Exception ignored){}

return null;

That's working perfect. I receive my text without problems.
I try the same approach in iOS that way:

int end = [encryptedText length]/2+1;
int start = end - 9;
//Get key
NSString *key = @"MYKEYUSEDBEFORE;
key = [[StringEncryption alloc]  sha256:key length:32];
//Cut out iv from encryptedText
NSString *iv = [encryptedText substringWithRange:NSMakeRange(start, 16)];
//Replace iv in encryptedText
encryptedText = [encryptedText stringByReplacingOccurrencesOfString:iv withString:@""];
//Decyrpt
 NSData *resultData = [[StringEncryption alloc] decrypt:[encryptedText dataUsingEncoding:NSUTF8StringEncoding] key:key iv:iv];
    NSString *result = [[NSString alloc]initWithData:resultData encoding:NSUTF8StringEncoding];
    return result;

But result is always null.

I can confirm that the iv is correct, it's definitely the same as used for encryption and the encryptedText after replacing the iv is exactly the same as after encryption and before putting in the iv.
So, what am I doing wrong?

Thanks a lot!

Best regards

Thanks for sharing the code.
the IOS dsnt decrypt string if it is generated via java/C# the same is the case with encryption, please help

Thanks

I have added all files into my Swift Project (CryptLib.h/CryptLib.m/NSData+Base64.h/NSData+Base64.m) and also I have added <UIKit/UIKit.h> to all .h files. Some errors gone but I can not use this class inside my swift classes.

I'd appreciate if anyone could provide some examples in SWIFT cause most of programmers are using SWIFT nowadays.

Thanks...

Hi,

We need to encrypt/decrypt string between IOS,android and C# app.We have used this class and it works in C# and android but not working in IOS. Please check for IOS compatibility before use.

Regards

It will be great to provide support for node.js web services primarily built on express.js framework. Let me know if i could contribute.

Hi,

Can you please provide AES-encryption algorithm for J2ME blackberry 7.i am not able to find this library anywhere.

We have followed exactly the same approach given here for IOS and C#. But unfortunately we are getting two different results.

We hardcoded IV key and Secret key and tested. Even this scenario into different results.

Let us know that any one has resolved this issue.

Any help is appreciated.

Thanks in advance

SHA256 is not an acceptable KDF. consider using PBKDF2 or a newer KDF.

Hi,
I'm using this library in iOS App, as well as our Android team, but at Java server its receiving the encrypted request, but when they decrypt it, its getting error "Bad padding exception: Given Final Block Not Properly Padded", but its working fine on Android.
I'm also getting a response, but the data is not Decrypting. And at Android its working fine as they use same android code on Java servers. But it's not supporting me, can you kindly help me with it.
Thanks,

Same IV and key using at JAVA server,android and IOS [hardcoded for testing].
NSString* const IV = @"288dca8258b1dd7c";
NSString* const key = @"c292a6e6c19b7403cd87949d0ad45021";

My approach as in CryptLib.m

//encrypt

• (NSString_) encryptString:(NSString_)XMLRequest withKey:(NSString *)key
  {
  NSData * encryptedData = [[StringEncryption alloc] encrypt:[XMLRequest dataUsingEncoding:NSUTF8StringEncoding] key:key iv:IV];
  NSString * encryptedXML = [encryptedData base64EncodingWithLineLength:0];

   return encryptedXML;
  

  }

//decrypt

• (NSData_) decryptData:(NSData_)XMLResponse withKey:(NSString *)key
  {
  NSString *responseString = [[NSString alloc] initWithData:XMLResponse encoding:NSUTF8StringEncoding];
  NSLog(@"responseString--------------------------%@",responseString);

  //

  NSData * decryptedData = [[StringEncryption alloc] decrypt:XMLResponse key:key iv:IV];

  //

  NSString * decryptedXML = [[NSString alloc] initWithData:decryptedData encoding:NSUTF8StringEncoding];
  NSLog(@"decrypted data:: %@", decryptedXML);

  return decryptedData;
  // this data sent for xml parsing
  }

Hi,

you library works fine but in my Android Application (API Level 22) when I'm try to encode a string I get one which contains "new line" characters \n; I'm using my static passphrase instead a SHA or MD5 generator functions.

I'm looking into your code and I find in encryptDecrypt() function at lines 154 and 163 the DEFAULT setting for Base64 enconde; I try to change this value this with Base64.NO_WRAP (from Base64.java doc: "Encoder flag bit to omit all line terminators (i.e., the output will be on one long line)").

With this fix the encoding works fine (without new line characters).
Do yo try to test your library with this setting?

Thank you!
Cheers

I am trying to compile this pkg in IOS it doesn't compile . But if I add

• (NSString *) base64EncodingWithLineLength:(unsigned int) lineLength ;

In NSData+Base64.h programpile

But when I use

NSString * _secret = @"This the sample text has to be encrypted"; // this is the text that you want to encrypt.
NSString * key = @"shared secret"; //secret key for encryption. To make encryption stronger, we will not use this key directly. We'll first hash the key next step and then use it.
NSString * _key = [[StringEncryption alloc] sha256:key length:32]; //this is very important, 32 bytes = 256 bit
NSString * iv = [[[[StringEncryption alloc] generateRandomIV:11] base64EncodingWithLineLength:0] substringToIndex:16];
NSData * encryptedData = [[StringEncryption alloc] encrypt:[_secret dataUsingEncoding:NSUTF8StringEncoding] key:_key iv:iv];
NSLog(@"encrypted data:: %@", [encryptedData base64EncodingWithLineLength:0]); //print the encrypted text

I get coredump

Hi, while I am encrypting the string, I am getting blank spaces in encrypted string in android. Please let me know how to fix it.

Hi. i use this library for Android and IOS in native. it's work fine in Android but in IOS it return different result. i try to encrypt "121212". in Android it return "qu6BVyPREpc5tnV1M1h7rw==" but in IOS it return different output each time.
Thanks

I am using your AES Encryotion for a month, now i have problems when i encrypt my JSON string. It will give us broken JSON String.

Example: {"id": 123, "name": "chonex"} then convert this to AES Encryption. Then, i will put this to JSON String again with a RANDOM IV. This will be like this: {"encrypted" : "asdqwrqtreywetusdmg", "randomIV" : "qrqetyers"}. And pass this to my IOS or Android, But when i decrypt this to ios or android platform, it will be broken. The decryted string will be like:' {"id": 123, "name": "chone ' with missing ' x"}'

Please considered commenting this if you have same issue on mine. thanks

Hi, i tried your library in my IOS project *Swift, and it didnt work, not because it is made in OBJC but because of the lack of instructions for IOS about how to install and use, i did a copy of the files in my project and everything went weird, red error messages and yellow ones...

Please add documentation, Thank you.

OC version use pkcs7Padding,android version use pkcs5padding

Can this work on php or are you plainig to provide it on php also.

Hi,
I'm using the encrypt method on .NET, then passing the IV and cipher to the decrypt method in node.js but I'm getting this error.

Error: error:06065064:digital envelope routines:EVP_DecryptFinal_ex:bad decrypt

Are you able to help me?
Thanks.

Hi,

I have been facing a similar problem as this issue #24

Been using this library for Java Server Side as well as on Android without any issues.

The issue is the string encrypted on Java server is not being decrypted on the iOS side. Where do you think I might be going wrong with this?

Code uses lenght of the input sting but is should use length of array GetBytes returns.
Fixed code should be something like that:
if (mode.Equals(EncryptMode.Encrypt))
{
//encrypt
var encbytes = _enc.GetBytes(inputText);
byte[] cypheredText = _rcipher.CreateEncryptor().TransformFinalBlock(encbytes, 0, encbytes.Length);
_out = Convert.ToBase64String(cypheredText);
}

I use your code to encrypt/decrypt text.
In c# it works perfect, but in xcode i need some help.
Firstly i make some changes and the encryption works perfect as in c#.
Now i have problem with decryption.
Here is the code of calling:

NSString * secret = @"1234";
    NSString * key = @"mykey";
    NSString * iv = @"myiv";
    NSData * encryptedData = [[CryptLib alloc] encrypt:[secret dataUsingEncoding:NSUTF8StringEncoding] key:key iv:iv];
    NSString *encryptedText = [encryptedData  base64EncodingWithLineLength:0];
    [self showUIAlertWithMessage:encryptedText andTitle:@"ecryption"];

    NSData * decryptedData = [[CryptLib alloc] decrypt:[encryptedText dataUsingEncoding:NSUTF8StringEncoding]  key:key iv:iv];
    NSString * decryptedText = [decryptedData  base64EncodingWithLineLength:0];
    [self showUIAlertWithMessage:decryptedText andTitle:@"decryption"];

and the code from CryptLib:

encryption result getting properly but decryption result getting null.How can we resolved that?
i am just checking with hard code data in both android and ios but its working properly in android.

Before star thanks for the code! very useful.
I having a problem with big texts, its always cutting the text in some point, I'm not sure if it is cutting the text in the encryption or in the decryption process.
Thanks!

Any plan to add JavaScript version?

This is response from c# wcf service. We figure out that when the data have "ñ" , the encryption is incomplete.

I have noticed that array inbuf in method (id) initWithBase64EncodedString:(NSString *) string of file NSData+Base64.m is decleared with unsigned char inbuf[3]. However, code in line 79 uses out-of-bound array index:

outbuf [2] = ( ( inbuf[2] & 0x03 ) << 6 ) | ( inbuf[3] & 0x3F ); //inbuf[3] is out-of-bound

I think array inbuf should be declared as unsigned char inbuf[4] to prevent array out-of-bound access violation.

Hi,
I have a problem with C# when I try encrypt and decrypt with text have 15000 characters.
when I encrypted, I get a other strings. then I decrypted this string I get a string , It's different from the original string. it miss at the end.

Function Parameter name is different while String used in function is different

public static final String md5(final String inputString) {

while used one is
digest.update(s.getBytes());

change it to
digest.update(inputString.getBytes());

Please update your code.

Thanks

I'm not able to encrypt a text with emojis in the server, and decrypt it in iOS.
Have you tested it?
Is there a way to do it?

Thanks

First of all thanks for the great library
This is actually not a big issue but on how to use section

Android hashes the key as follows;
string key = CryptLib.getHashSha256("my secret key", 31);
C# hashes as follows;
String key = CryptLib.SHA256("my secret key", 32); //32 bytes = 256 bit

Which gave us at the beginning different results then I have changed the C# code to use 32bytes and results were identical.

This library uses ECB mode, making it unsuitable for most users.

i have a one c# web service and i can decript and encript c# webservice, android project and c# client project. but i can not implement pakhee ios code for my ios application. There are a lot of error in ios classes. Could you fix ios classes and give usage example for ios application?

Hey guys,

I wanted to try this cross-platform encryption and realized that it is not working with swift (2.0).
There are a few errors and warnings.

1. The errors in CryptLib.h can be fixed by importing UIKit:

import < UIKit/UIKit.h > //Remove whitespaces

In NSData+Base64 I get two warnings and one error I can't fix.

1. Warning: "Method definition for 'dataFromBase64String:' not found"

2. Warning: "Array index 3 is past the end of the array (which contains 3 elements)

    outbuf [2] = ( ( inbuf[2] & 0x03 ) << 6 ) | ( inbuf[3] & 0x3F );
   

3. Error: "'autorelease' is unavailable: not available in automatic reference counting mode'

Maybe someone can help me?

Upadte 1: I fixed the Error by turning off the "Objective-C Automatic Reference Counting" in my Build Settings

Hello,
I think there's a typo in "HowToUse.cs"
At line 7

string key = CryptLib.getHashSha256("my secret key", 31);

There is "31": this causes a wrong padding exception in asp.net c# code.
I was testing encryption on Android side and decryption on C# server-side.
Using value "32" everything works fine.

Pretty much what title says. Add support for encyrpting and decrypting byte arrays and providing byte arrays keys and IVs.
