NAME

My::Crypt - Perl extension for blah blah blah

SYNOPSIS

use My::Crypt;

$crypt = My::Crypt->new( debug => 0 );

[or]

$crypt = My::Crypt->new( debug => 0, encoding => 'hex8' );

Encryption

$encrypted = $crypt->encrypt('plain text to encrypt', 'your_secret_string');

Decryption

$decrypted = $crypt->decrypt($encrypted, 'your_secret_string');

Returns an empty string if the encrypted hash has been broken

DESCRIPTION

Sometimes it's necessary to protect some certain data against plain reading or you intend to send information through the Internet. Another reason might be to assure users cannot modify their previously entered data in a follow-up step of a long Web transaction where you don't want to deal with server-side session data. The goal of My::Crypt was to have a pretty simple way to encrypt and decrypt data without the need to install and compile huge packages with lots of dependencies.

My::Crypt generates every time a different encrypted hash when you re-encrypt the same data with the same secret string. Nevertheless you are able to make double or tripple-encryption with any data to increase the security. Decryption works also on hashes that have been encrypted on a foreign host (try this with an unpatched IDEA installation ;-).

EXPORT

None by default.
