Crypt::OpenSSL3::Cipher - an abstraction around ciphers

VERSION

version 0.002

SYNOPSIS

my $cipher = Crypt::OpenSSL3::Cipher->fetch('AES-128-GCM');
my $context = Crypt::OpenSSL3::Cipher::Context->new;
$context->init($cipher, $key, $iv, 1);
my $ciphertext = $context->update($plaintext);
$ciphertext .= $context->final;
my $tag = $context->get_aead_tag(16);

my $context2 = Crypt::OpenSSL3::Cipher::Context->new;
$context2->init($cipher, $key, $iv, 0);
my $decoded = $context2->update($ciphertext);
$context2->set_aead_tag($tag);
$decoded .= $context2->final // die "Invalid tag";
