example

 Example 

iex> encryption_key = "very-secretive"
iex> {:ok, encrypted} = Secrex.AES.encrypt("Hello, World!", encryption_key)
iex> Secrex.AES.decrypt(encrypted, encryption_key)
{:ok, "Hello, World!"}

Functions

decrypt(ciphertext, key)

Decrypts data using AES-256-GCM.

decrypt(ciphertext, key, aad)

Same as decrypt/2 but also accepts additional authenticated data (AAD).

encrypt(plaintext, key)

Encrypts data using AES-256-GCM.

encrypt(plaintext, key, aad)

Same as encrypt/2 but also accepts additional authenticated data (AAD).
