Encrypted NSData to NSString in obj-c?

http://stackoverflow.com/questions/1417893/encrypted-nsdata-to-nsstring-in-obj-c

key are given to the encryption method which returns an NSData object. Requesting data description where 'data' is the encrypted string data gives an NSString like 0b368353 a707e7de 3eee5992 ee69827e e3603dc2 b0dbbc0b 861ca87d f39ce72a but when I try.. apologize if my previous answer misled you I was merely printing the description to demonstrate that the NSData can be encrypted and decrypted. Instead use NSString's dataUsingEncoding and initWithData encoding methods to convert between NSData and.. and initWithData encoding methods to convert between NSData and NSString. Even with these note that AES encrypted data will probably not translate well into strings as is some byte sequences just won't play nicely so it's a good idea..
