RSA Ex

Library for working with RSA keys using Elixir and OpenSSL ports.

Installation

If available in Hex, the package can be installed as:

Add rsa_ex to your list of dependencies in mix.exs:

def deps do
  [{:rsa_ex, "~> 0.4"}]
end

Ensure rsa_ex is started before your application:

def application do
  [applications: [:rsa_ex]]
end

Usage

Generate RSA 2048 Private Key

iex> {:ok, priv} = RsaEx.generate_private_key

Generate RSA 2048 Public Key

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

Generate RSA 4096 Public Key

iex> {:ok, priv} = RsaEx.generate_private_key("4096")
iex> {:ok, pub} = RsaEx.generate_public_key(priv)

Generate RSA 2048 Private/Public Keypair

iex> {:ok, {priv, pub}} = RsaEx.generate_keypair

Generate RSA 4096 Private/Public Keypair

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

Sign message with RSA private key

iex> {:ok, rsa_private_key} = RsaEx.generate_private_key
iex> {:ok, signature} = RsaEx.sign("message", rsa_private_key)

Sign message with RSA private key specifying a custom dygest type

iex> {:ok, rsa_private_key} = RsaEx.generate_private_key
iex> {:ok, signature} = RsaEx.sign("message", rsa_private_key, :sha512)

Verify signature with RSA public key

iex> {:ok, valid} = RsaEx.verify(message, signature, rsa_public_key)

Verify signature with RSA public key specifying a custom dygest type

iex> {:ok, valid} = RsaEx.verify(message, signature, rsa_public_key, :sha512)

Encrypt message with RSA public key in base64

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

Encrypt message with RSA private key in base64

iex> clear_text = "Important message"
"Important message"
iex> {:ok, cipher_text} = RsaEx.encrypt(clear_text, {:private_key, rsa_private_key})
{:ok, "Lmbv...HQ=="}

Decrypt message with RSA private key

iex> {:ok, decrypted_clear_text} = RsaEx.decrypt(cipher_text, {:private_key, rsa_private_key})
{:ok, "Important message"}

Decrypt message with RSA public key

iex> {:ok, decrypted_clear_text} = RsaEx.decrypt(cipher_text, {:public_key, rsa_public_key})
{:ok, "Important message"}
