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

Question

So as many of you may already know, CommonCrypto isn\'t included in the iPhone SDK anymore (as on 3.0).

Where else can I easily get hold of an MD5 function? Am I goi

Answer 1

Are you sure its not included? I have apps compiled on the 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(cStr, strlen(cStr), result); 
    return [NSString stringWithFormat: @"%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X",         
            result[0], result[1], result[2], result[3],
            result[4], result[5], result[6], result[7],
            result[8], result[9], result[10], result[11],
            result[12], result[13], result[14], result[15]];    
}
