Crypt::OpenPGP 1.03

Crypt::OpenPGP is a Pure-Perl OpenPGP implementation.

SYNOPSIS

my $pgp = Crypt::OpenPGP->new;
my $result = $pgp->handle( Data => $message_body );

my $signature = $pgp->sign(
Filename => $file,
KeyID => $key_id,
Passphrase => $pass,
Detach => 1,
Armour => 1,
);

my $valid = $pgp->verify(
Signature => $signature,
Files => [ $file ],
);

my $ciphertext = $pgp->encrypt(
Filename => $file,
Recipients => $key_id,
Armour => 1,
);

my $plaintext = $pgp->decrypt(
Data => $ciphertext,
Passphrase => $pass,
);

Crypt::OpenPGP is a pure-Perl implementation of the OpenPGP standard[1]. In addition to support for the standard itself, Crypt::OpenPGP claims compatibility with many other PGP implementations, both those that support the standard and those that preceded it.

Crypt::OpenPGP provides signing/verification, encryption/decryption, keyring management, and key-pair generation; in short it should provide you with everything you need to PGP-enable yourself. Alternatively it can be used as part of a larger system; for example, perhaps you have a web-form-to-email generator written in Perl, and youd like to encrypt outgoing messages, because they contain sensitive information. Crypt::OpenPGP can be plugged into such a scenario, given your public key, and told to encrypt all messages; they will then be readable only by you.

This module currently supports RSA and DSA for digital signatures, and RSA and ElGamal for encryption/decryption. It supports the symmetric ciphers 3DES, Blowfish, IDEA, Twofish, CAST5, and Rijndael (AES). Rijndael is supported for key sizes of 128, 192, and 256 bits. Crypt::OpenPGP supports the digest algorithms MD5, SHA-1, and RIPE-MD/160. And it supports ZIP and Zlib compression.
