NAME

Crypt::PBE::PBES2 - Perl extension for PKCS #5 Password-Based Encryption Schema 2 (PBES2)

SYNOPSIS

use Crypt::PBE::PBES2;

my $pbes2 = Crypt::PBE::PBES2->new(
    'hmac'       => 'hmac-sha256',
    'encryption' => 'aes-128',
    'password'   => 'mypassword'
);

my $encrypted = $pbes2->encrypt('secret');
say $pbes2->decrypt($encrypted); # secret

DESCRIPTION

PBES2 combines a password-based key derivation function, which shall be PBKDF2 with an underlying encryption scheme. The key length and any other parameters for the underlying encryption scheme depend on the scheme.

PBES2 is recommended for new applications.

CONSTRUCTOR

Crypt::PBE::PBES2->new ( %params )

Params:

  • password : The password to use for the derivation

  • hmac : HMAC digest algorithm ("hmac-sha1", "hmac-sha224", "hmac-sha256", "hmac-sha384" or "hmac-512")

  • encryption : Encryption method ("aes-128", "aes-192" or "aes-256")

  • count : The number of internal iteractions to perform for the derivation key (default "1_000")

METHODS

$pbes2->encrypt( $message )

Perform the encryption and return the encrypted message in binary format.

You can encode the encrypted message in Base64 using MIME::Base64:

$b64_encrypted = encode_base64 $pbes2->encrypt('secret');

$pbes2->decrypt( $data )

Perform the decryption and return the original message.

$decrypted = $pbes2->decrypt($encrypted);

You can decode the Base64 encrypted message using MIME::Base64:

$decrypted = $pbes2->decrypt(decode_base64 $b64_encrypted);
