View Full Version : MD5 Password encryption?

Aug 29, 2008, 01:19 AM
Is there a built in API call where I can MD5 encrypt a string? My app needs to send a password to a server, and i would like to encrypt it before sending it.

How can I go about doing this? I dont see any mention of MD5 encryption in the api documentation.

Look at the CommonDigest.h header.

I used this C function with the header files Kainjow mentioned

NSString * md5Digest( NSString *str )
const char *cStr = [str UTF8String];
unsigned char result[CC_MD5_DIGEST_LENGTH];
CC_MD5( cStr, strlen(cStr), result );
return [NSString stringWithFormat:
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]
