Encrypt in Objective-C / Decrypt in Ruby using anything

Question

We are using this code to encrypt in Objective-C on the iPhone:

- (NSMutableData*) EncryptAES: (NSString *) key
{
    char keyPtr[kCCKeySizeAES128+1];
    bz         


        

Answer 1

You could as well use the following libs providing in-built AES-256-CBC cipher and Base64 encoding that you can use across both platforms quickly:

Ruby

https://github.com/Gurpartap/aescrypt

Here's how you would use the AESCrypt Ruby gem:

message = "top secret message"
password = "p4ssw0rd"

# Encrypting
encrypted_data = AESCrypt.encrypt(message, password)

# Decrypting
message = AESCrypt.decrypt(encrypted_data, password)

---

Objective-C

https://github.com/Gurpartap/AESCrypt-ObjC

Here's how you would use the AESCrypt Objective-C class:

NSString *message = @"top secret message";
NSString *password = @"p4ssw0rd";

// Encrypting
NSString *encryptedData = [AESCrypt encrypt:message password:password];

// Decrypting
NSString *message = [AESCrypt decrypt:encryptedData password:password];

Hope it helps!
