CommonCrypto is no longer part of the iPhone SDK - Where else can I easily get an MD5 function?

just to get MD5 A few clarifications This isn't for security This is going to be used with an API that requires an MD5 digest of a string. I have no control over this API. If I could use SHA256 I would. I'm all for moving forward but I can't change.. device for 3.0 using the following code that works #import CommonCrypto CommonDigest.h #define CC_MD5_DIGEST_LENGTH 16 digest length in bytes NSString md5 NSString str const char cStr str UTF8String unsigned char result CC_MD5_DIGEST_LENGTH CC_MD5..
