Functions

Decrypt message with RSA private key

iex(8)> {:ok, decrypted_clear_text} = Fulib.RSA.decrypt(cipher_text, rsa_private_key)
{:ok, "Important message"}

Encrypt message with RSA public key in base64

iex> clear_text = "Important message"
"Important message"
iex> {:ok, cipher_text} = Fulib.RSA.encrypt(clear_text, rsa_public_key)
{:ok, "Lmbv...HQ=="}

Generates RSA private/public keypair of {bits} size. Default is 4096.

iex> {:ok, {priv, pub}} = Fulib.RSA.generate_keypair("4096")

Generates RSA private key of {bits} size. Default is 4096.

iex> {:ok, priv} = Fulib.RSA.generate_private_key("4096")

Generates RSA public key

iex> {:ok, priv} = Fulib.RSA.generate_private_key
iex> {:ok, pub} = Fulib.RSA.generate_public_key(priv)

Sign message with RSA private key

iex> {:ok, signature} = Fulib.RSA.sign(message, rsa_private_key)
{:ok, <<...>>}

Verify signature with RSA public key

iex> {:ok, valid} = Fulib.RSA.verify(message, signature, rsa_public_key
{:ok, true}
