Perl example code showing how to generate an RSA public/private key pair and export to PEM files.

Note: This example requires Chilkat v11.0.0 or greater.

use chilkat();

$success = 0;

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

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

# Generate a 2048-bit key.  Chilkat RSA supports
# key sizes ranging from 512 bits to 8192 bits.
$privKey = chilkat::CkPrivateKey->new();
$success = $rsa->GenKey(2048,$privKey);
if ($success == 0) {
    print $rsa->lastErrorText() . "\r\n";
    exit;
}

$pubKey = chilkat::CkPublicKey->new();
$privKey->ToPublicKey($pubKey);

# Save the private key in PEM format:
$success = $privKey->SavePemFile("privateKey.pem");
if ($success == 0) {
    print $privKey->lastErrorText() . "\r\n";
    exit;
}

# Save the public key in PEM format:
$success = $pubKey->SavePemFile(0,"publicKey.pem");
if ($success == 0) {
    print $pubKey->lastErrorText() . "\r\n";
    exit;
}

print "Success." . "\r\n";
