Encryption library for Objective-C

开发者_Python百科

Other than OpenPGP, are there any other libraries to encrypt text?

You could use OpenSSL, which is built into both Mac OS X and iOS. You just need to add Security.framework, then you can #include <ssl.h>.

For simple encryption using AES, TripleDES, you can just use built-in CommonCrypto library,
