    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

    Code:
    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:
    			@"%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]
    	];
    }
