gurpartap / aescrypt-objc Goto Github PK

Hi,

I have a string that I want to decode: U2FsdGVkX1+MEhsbofUNj58m+8tu9ifAKRiY/Zf8YIw= and I have this key: 3841b8485cd155d932a2d601b8cee2ec .
I can't decrypt the string using AESCrypt-ObjC
Are there any more details that I should be aware about the encryption?

Thank you,
George

The code work well for me. But would you like to support cocoa pods?

it will be crash if i run my app on ios6 ,it seemed that nsdata+base64 not support , when i moidfied nsdata+base64.m ,it will be ok~

I got this error message

/Users/MNurdin/Documents/iOS/RevivalxSwiftAESCrypt/RevivalxSwiftAESCrypt/AESCrypt/NSString+Base64.m:28:14: Definition of 'NSData' must be imported from module 'Foundation.NSData' before it is required

Code

lentext = [data length]; 

Please advice. Thank you.

Hi guys, the project works perfectly but I noticed one bit issue.
When someone encrypts one and the same plaintext will get one and the same cyphertext. This means that if someone listens in the middle - the bad Eve she will be able to guess what has been sent.

Normally the password will never change for an application and I assume that this could be used to encrypt url requests for example - small length of strings. In such use I do not think that is secure enough.

What should be done is to introduce salt - random length. Something which is done in C# here: http://www.obviex.com/samples/encryptionwithsalt.aspx

I need that for a personal project and need to encrypt and decrypt this random cyphertext in iOS app and on web server with C#. Will try to implement that in objective-c and contribute if possible to your project.

Hello there,

I saw a closed issue about IV support and I can see from this code that IV is supported... But with a fixed IV, isn't it?

I mean, what usually happens is:

• encrypt with a random generated IV and add the IV at the beginning of the encrypted data (for instance 16 random characters)
• decrypt by extracting the IV at the beginning (first 16 characters) of the encrypted string and then decrypt...

Is this doable?

Thanks a lot...

It crashes the app if you keep the default optimization level of Release build as the 'Fastest'. So changing from the defaults to 'None' helped solve crashes!

Your code have problem, kindly solve it.

I got problem with this library where I can't found any encrypt and decrypt functions using bridging header.

My code

let instanceAESCrypt = AESCrypt()

Hi Gurpratap,
My app crashing for below line
NSData *encryptedData = [[message dataUsingEncoding:NSUTF8StringEncoding] AES256EncryptedDataUsingKey:[[password dataUsingEncoding:NSUTF8StringEncoding] SHA256Hash] error:nil];

with exception
-[NSConcreteMutableData SHA256Hash]: unrecognized selector sent to instance

I am testing this code.
The result is different from the site http://aes.online-domain-tools.com/

I appreciate if anybody can tell an advice to test the result.

Thank you in advance

re:

https://github.com/Gurpartap/AESCrypt-ObjC/blob/master/NSData%2BCommonCrypto.m#L177

The method name says AES256, but the algorithm identifier uses AES-128. The key being passed in is also the output from SHA-256, so it's a 256-bit key.

Mismatches?

Hi,

Thanks for the code. It really helps and we are getting same result in iOS and Android with your code. Now we need to decrypt this code through PHP code.

Is there any code available which directly decrypting it by providing key?
