Getting decrypted data using CryptLib about cross-platform-aes-encryption

[navneet83]

What is the expected Decrypted data ? This looks like duplicate of this issue - #10 (comment)

Make sure your IV is 16 characters and consider randomizing your IV.

Hello Navneet,
My encrypted string is :
97Dfy+pLJFA+RqYR8nX8YFr6JuVC5UUOQceV93kN4aUU+qUvjMa+2Z1iifcrG/U6

Actual string is :

This is test Encryption String One

string iv = "VFSGlobalApp";

string key = CryptLib.getHashSha256("VFSGlobalApp", 31); //32 bytes = 256
bits

Then i decrypt this encrypted text then i get nothing.

Thanks & Regards,
Manish Mundra

Did you read my previous comment and implement changes accordingly ?

Yes, i did but response is not according my encrypted string.

NSString *iv = @"GlobalApp";

NSString *key = [[CryptLib alloc]sha256:@"GlobalApp"

length:32];//getHashSha256(@"GlobalApp", 31); //32 bytes

NSString * secret = @"This is test Encryption String Two";

• Output : *

r+jolqNoBBq/XCV9rrXzQwmFt8jCD/AHYdzIG/ECVUAVFsAIaYOQy+xzYrq8/Ayx

NSData * encryptedData = [[CryptLib alloc] encrypt:[secret

dataUsingEncoding:NSUTF8StringEncoding] key:key iv:iv];

NSString *encryptedText = [encryptedData

base64EncodingWithLineLength:0];

NSData * decryptedData = [[CryptLib alloc] decrypt:[encryptedText

dataUsingEncoding:NSUTF8StringEncoding] key:key iv:iv];

NSString * decryptedText = [decryptedData

base64EncodingWithLineLength:0];

*Output : *

What is your IV ? In your code you have used - NSString *iv = @"GlobalApp"; This has just 9 characters while I had mentioned that you'll need at least 16 characters.
