Hi, I had to spend some time looking into this recently myself. You have two options:
1 - K. Miyako has a plugin - CommonCrypto. Easy to use. $signature:=HMACSHA256 ($keyData;$stringData;Crypto BASE64) 2 - Use PHP execute, but then encode the result (assuming you need to) php way if we ever need it - do not delete $phpOK:=PHP Execute("";"hash_hmac";$sigBlob;"sha256";$stringToSign;$key;True) BASE64 ENCODE($sigBlob) $signature:=Convert to text($sigBlob;"utf-8") -- Sent from: http://4d.1045681.n5.nabble.com/4D-Tech-f1376241.html ********************************************************************** 4D Internet Users Group (4D iNUG) Archive: http://lists.4d.com/archives.html Options: https://lists.4d.com/mailman/options/4d_tech Unsub: mailto:4d_tech-unsubscr...@lists.4d.com **********************************************************************
