Specs

decrypt(binary(), binary()) :: binary()

Decrypts ciphertext using key. Ciphertext is init. vector, ciphertag (MAC) and the actual ciphertext concatenated.

Specs

deserialize(binary()) :: {:ok, pid()} | {:error, :not_base64 | :invalid_term}

Convert a serialized string back into a pid.

Specs

deserialize!(binary()) :: pid()

Convert a serialized string back into a pid.

Specs

encrypt(binary(), binary()) :: binary()

Encrypts value using key and returns init. vector, ciphertag (MAC) and ciphertext concatenated. Additional authenticated data (AAD) adds parameters like protocol version num. to MAC

Specs

hash(binary()) :: binary()

The function processes any string or number and returns exactly 16 byte binary. The hash produced by this function can be used as key by both encrypt and decrypt functions.

Specs

serialize(pid()) :: binary()

Turn a pid into an url-encoded string.
