pvasa / easycrypt Goto Github PK

Hi there, please i need help with this question in stackoverflow:

https://stackoverflow.com/questions/55662883/encrypt-data-with-cryptoswift-coming-from-easycrypt

The android developer used this library inside one application but when i try to decrypt data from iOS (with CryptoSwift), i don't get the excepted results. Some help please ??

Describe the bug
Release 1.3.5 build is broken.
https://jitpack.io/com/github/pvasa/EasyCrypt/1.3.5/build.log

To Reproduce
Steps to reproduce the behavior:
See log: https://jitpack.io/com/github/pvasa/EasyCrypt/1.3.5/build.log

Expected behavior
Library should install correctly when installed using Gradle. Currently only the randomorg package is built inside the library.

Screenshots
If applicable, add screenshots to help explain your problem.

Smartphone (please complete the following information):

• Device: [e.g. iPhone6]
• OS: [e.g. iOS8.1]
• Version [e.g. 22]

Additional context
Add any other context about the problem here.

Early 2022 Jcenter will become unavailable. This is currently the only source to obtain this package. Migration to Jitpack or MavenCentral could solve the problem.

Thank you for this project. I have a hex signature string, what do I need to convert it to in order to use the eCryptAsymmetric.verify() function? Thank you

I am trying to run a method once the encryption is done with the help of the ECResultListener like below:

String fileKey = "123456";
                        ECSymmetric ecSymmetric = new ECSymmetric();
                        ecSymmetric.encrypt(orginaFile, fileKey, new ECResultListener() {
                            @Override
                            public void onProgress(int newBytes, long processedBytes, long totalBytes) {

                            }

                            @Override
                            public <T> void onSuccess(T t) {
                                    Toasty.success(singleChatActivity.this, "ENCRYPTED").show(); // DOESN'T display although there is an encrypted file as an result
                            }

                            @Override
                            public void onFailure(String s, Exception e) {

                            }
                        }, encryptedFile);

Any help?

Cannot access library classes after importing from jcenter

I am trying to decrypt an image after the downloading from Firebase storage directly (in OnSuccessListener) and the log of the progress of decryption works till it reaches 99% and gives the following error:
Cannot write to file.java.io.IOException: Error while finalizing cipher
Please note:

• The premissions are granted.
• The decryption works in other locations.

Any recommendations for this?

EDIT: to clarify the problem - encryption and decryption on the same platform works! The problem is when you encrypt information on some platforms and then afterwards, decryption of this data is attempted on others. I've seem compatibility problems between these ranges of API versions:

• 22 or before,
• 23 through 25,
• 26 and after,

meaning, encryption-decryption between devices in each range works, but between devices in different ranges doesn't.

It seems that this library is experiencing the same issue found in this other library below (in an older version, they fixed it by enforcing usage of Bouncy Castle instead of the new default provider on Android 6.0 onwards).

AArnott/PCLCrypto#61

Please also make this library enforce usage of Bouncy Castle as well as a workaround at least until a fix is found using the new provider on API 23 onwards.
EDIT: As I mention below, apparently just doing this workaround won't be enough :(

I tested on an emulator with API 26.

Thank you!

I am trying to send encrypted files through Firebase storage, when the same encryption/decryption works pretty fine on the same device where I encrypt the data, it gives the following error after 99% of the decryption on another device:

E/Cannot write to file.: java.io.IOException: Error while finalizing cipher

Please note that the encryption string key is the same and also the same function to decrypt the file in both devices. Is there something I am missing here?
