Subroutines/Functions
decrypt_from_config
$plain_text = decrypt_from_config( $params, $password );Strips the {Twofish2} prefix and then decrypts the password
encrypt_for_config
$encrypted_value = encrypt_for_config( $params, $plain_text );Returns the encrypted value of the plain value prefixed with {Twofish2} for storage in a configuration file
get_cipher
$cipher = get_cipher( $encrypted_value );Returns the name of the cipher used to encrypt the value
is_encrypted
$bool = is_encrypted( $password_or_encrypted_value );Return true if the passed argument matches the pattern for an encrypted value
__extract_crypt_params
($cipher, $password) = __extract_crypt_params( $encrypted_value );Extracts the cipher name and the encrypted password from the value stored in the configuration file.
