NAME

DTOne::Crypt - Cryptographic Toolkit

SYNOPSIS

  use DTOne::Crypt qw(encrypt_aes256gcm decrypt_aes256gcm);

  my $encrypted = encrypt_aes256gcm($plaintext, $master_key);
  my $decrypted = decrypt_aes256gcm($encrypted, $master_key);

DESCRIPTION

DTOne::Crypt provides a cryptographic toolkit intended to abstract complexities in data interchange.

FUNCTIONS

DTone::Crypt implements the following functions, which can be imported individually:

encrypt_aes256gcm

  my $encrypted = encrypt_aes256gcm($plaintext, $master_key);

Encrypt plaintext value using AES-256 GCM to a base64 encoded string containing the salt, initialization vector (IV), ciphertext, and tag.

decrypt_aes256gcm

  my $decrypted = decrypt_aes256gcm($encrypted, $master_key);

Decrypt a composite base64 encoded string containing the salt, IV, ciphertext, and tag back to its original plaintext value.
