Base64url Encoding

See more Encryption Examples

Base64url encoding is identical to base64 encoding except it uses non-reserved URL characters (e.g. '–' is used instead of '+', and '_' is used instead of '/') and it omits the padding characters. Perl

use chilkat();

$success = 0;

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

$pkey = chilkat::CkPrivateKey->new();
$rsa = chilkat::CkRsa->new();
$rsa->GenKey(1024,$pkey);
$rsa->UsePrivateKey($pkey);

$strData = "This is the string to be signed.";

# Get the signature in base64url
$rsa->put_EncodingMode("base64url");
$strSig = $rsa->signStringENC($strData,"sha256");

print $strSig . "\r\n";
