How to use CC_MD5 method in swift language

Question

in Objective-c, we can hash a string like this:

const char *cStr = [someString UTF8String];
unsigned char result[16];
CC_MD5( cStr, strlen(cStr), result );
m         


        

Answer 1

evntually if you want calculate MD5 out of NSData, take a look at this:

func md5() -> NSData {
    var ctx = UnsafePointer.alloc(sizeof(CC_MD5_CTX))
    CC_MD5_Init(ctx);

    CC_MD5_Update(ctx, self.bytes, UInt32(self.length));
    let length = Int(CC_MD5_DIGEST_LENGTH) * sizeof(Byte)
    var output = UnsafePointer.alloc(length)
    CC_MD5_Final(output, ctx);

    let outData = NSData(bytes: output, length: Int(CC_MD5_DIGEST_LENGTH))
    output.destroy()
    ctx.destroy()

    //withUnsafePointer
    return outData;
}

to get idea.
