Betreff: Re: HMAC SHA256 in native 4D code?
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")
