Generate RSA Key and return Base64 PKCS8 Private Key

See more RSA Examples

Demonstrates how to generate a new 2048-bit RSA private key and returns the Base64 encoded PKCS8 representation of the private key. Perl

use chilkat();

$success = 0;

$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;
}

# Get the private key in PKCS8 Base64 format
$privKeyPkcs8Base64 = $privKey->getPkcs8ENC("base64");

# The key in base64 format will start similar to this:
# MIIEvAIBADANBgkqhkiG9w0BA...
print $privKeyPkcs8Base64 . "\r\n";
