(Perl) RSA Encrypt and Decrypt StringsSee more RSA ExamplesPerl sample code to RSA public-key encrypt and decrypt strings using public and private keys.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(); # This example also generates the public and private # keys to be used in the RSA encryption. # Normally, you would generate a key pair once, # and distribute the public key to your partner. # Anything encrypted with the public key can be # decrypted with the private key. The reverse is # also true: anything encrypted using the private # key can be decrypted using the public key. # Generate a 2048-bit key. Chilkat RSA supports # key sizes ranging from 512 bits to 4096 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); $plainText = "Encrypting and decrypting should be easy!"; # Start with a new RSA object to demonstrate that all we # need are the keys previously exported: $rsaEncryptor = chilkat::CkRsa->new(); # Encrypted output is always binary. In this case, we want # to encode the encrypted bytes in a printable string. # Our choices are "hex", "base64", "url", "quoted-printable". $rsaEncryptor->put_EncodingMode("hex"); # We'll encrypt with the public key and decrypt with the private # key. $success = $rsaEncryptor->UsePublicKey($pubKey); $usePrivateKey = 0; $encryptedStr = $rsaEncryptor->encryptStringENC($plainText,$usePrivateKey); print $encryptedStr . "\r\n"; # Now decrypt: $rsaDecryptor = chilkat::CkRsa->new(); $rsaDecryptor->put_EncodingMode("hex"); $success = $rsaDecryptor->UsePrivateKey($privKey); $usePrivateKey = 1; $decryptedStr = $rsaDecryptor->decryptStringENC($encryptedStr,$usePrivateKey); print $decryptedStr .
