NAME

Crypt::Fernet - Perl extension for Fernet (symmetric encryption)

SYNOPSIS

use Crypt::Fernet;

my $key = Crypt::Fernet::generate_key();
my $plaintext = 'This is a test';
my $token = Crypt::Fernet::encrypt($key, $plaintext);
my $verify = Crypt::Fernet::verify($key, $token);
my $decrypttext = Crypt::Fernet::decrypt($key, $token);

my $old_key = 'cJ3Fw3ehXqef-Vqi-U8YDcJtz8Gv-ZHyxultoAGHi4c=';
my $old_token = 'gAAAAABT8bVcdaked9SPOkuQ77KsfkcoG9GvuU4SVWuMa3ewrxpQdreLdCT6cc7rdqkavhyLgqZC41dW2vwZJAHLYllwBmjgdQ==';

my $ttl = 10;
my $old_verify = Crypt::Fernet::verify($old_key, $old_token, $ttl);
my $old_decrypttext = Crypt::Fernet::decrypt($old_key, $old_token, $ttl);

my $ttl_verify = Crypt::Fernet::verify($key, $token, $ttl);
my $ttl_decrypttext = Crypt::Fernet::decrypt($key, $token, $ttl);

DESCRIPTION

Fernet provides guarantees that a message encrypted using it cannot be manipulated or read without the key. Fernet is an implementation of symmetric (also known as “secret key”) authenticated cryptography. This is the Perl Implementation
