(Perl) RSA Sign with PKCS8 Encrypted Key

Demonstrates how to load a private key from an encrypted PKCS8 file and create an RSA digital signature.

use chilkat();

$pkey = chilkat::CkPrivateKey->new();

#  Load the private key from an RSA PEM file:
$success = $pkey->LoadPkcs8EncryptedFile("privateKey.key","myPassword");

#  Get the private key in XML format:
$pkeyXml = $pkey->getXml();

$rsa = chilkat::CkRsa->new();

#  Any string argument automatically begins the 30-day trial.
$success = $rsa->UnlockComponent("30-day trial");
if ($success != 1) {
    print "RSA component unlock failed" . "\r\n";
    exit;
}

#  Import the private key into the RSA component:
$success = $rsa->ImportPrivateKey($pkeyXml);
if ($success != 1) {
    print $rsa->lastErrorText() . "\r\n";
    exit;
}

#  This example will sign a string, and receive the signature
#  in a hex-encoded string.  Therefore, set the encoding mode
#  to "hex":
$rsa->put_EncodingMode("hex");

#  If some other non-Chilkat application or web service is going to be verifying
#  the signature, it is important to match the byte-ordering.
#  The LittleEndian property may be set to 1
#  for little-endian byte ordering,
#  or 0  for big-endian byte ordering.
#  Microsoft apps typically use little-endian, while
#  OpenSSL and other services (such as Amazon CloudFront)
#  use big-endian.
$rsa->put_LittleEndian(0);

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

#  Sign the string using the sha-1 hash algorithm.
#  Other valid choices are "md2", "sha256", "sha384", "sha512",  and "md5".
$hexSig = $rsa->signStringENC($strData,"sha-1");

print $hexSig . "\r\n";
