NAME

Crypt::PBE::PBES1 - Perl extension for PKCS #5 Password-Based Encryption Schema 1 (PBES1)

SYNOPSIS

use Crypt::PBE::PBES1;

my $pbes1 = Crypt::PBE::PBES1->new(
    'hash'       => 'md5',
    'encryption' => 'des',
    'password'   => 'mypassword'
);

my $encrypted = $pbes1->encrypt('secret');
say $pbes1->decrypt($encrypted); # secret

DESCRIPTION

PBES1 combines the PBKDF1 function with an underlying block cipher, which shall be either DES or RC2 in cipher block chaining (CBC) mode.

PBES1 is recommended only for compatibility with existing applications, since it supports only two underlying encryption schemes, each of which has a key size (56 or 64 bits) that may not be large enough for some applications.

CONSTRUCTOR

Crypt::PBE::PBES1->new ( %params )

Params:

  • password : The password to use for the derivation

  • hash : Hash algorithm ("md2", "md5 or "sha1")

  • encryption : Encryption method ("des")

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

METHODS

$pbes1->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 $pbes1->encrypt('secret');

$pbes1->decrypt( $data )

Perform the decryption and return the original message.

$decrypted = $pbes1->decrypt($encrypted);

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

$decrypted = $pbes1->decrypt(decode_base64 $b64_encrypted);
