Holds private key data.

Parameters:

• :secret [binary/0]: private key secret number as bytes
• :curve [Tezex.Crypto.Curve.t/0]: private key curve information

@spec from_encoded_key(String.t(), String.t() | nil) :: {:ok, t()} | {:error, atom()}

Creates a private key from a Tezos encoded key string.

Supports both encrypted and unencrypted private keys in the formats:

• edsk... (Ed25519 seed or secret key)
• edesk... (Ed25519 encrypted seed)
• spsk... (Secp256k1 secret key)
• spesk... (Secp256k1 encrypted secret key)
• p2sk... (P256 secret key)
• p2esk... (P256 encrypted secret key)
• BLsk... (BLS12-381 secret key)
• BLesk... (BLS12-381 encrypted secret key)

Parameters

• encoded_key - Base58-encoded private key string
• passphrase - Passphrase for encrypted keys (optional)

Returns

• {:ok, private_key} - Successfully parsed private key
• {:error, reason} - Parsing failed

@spec from_encoded_key!(String.t(), String.t() | nil) :: t()

Creates a private key from a Tezos encoded key string (raises on error).

Parameters

• encoded_key - Base58-encoded private key string
• passphrase - Passphrase for encrypted keys (optional)

Returns

• private_key - Successfully parsed private key

Raises

• RuntimeError - When key parsing fails

@spec generate(nil | binary(), atom()) :: t()

Creates a new private key

Parameters:

• secret [binary/0]: private key secret. Default: nil -> random key will be generated
• curve_name [atom/0]: curve name. Default: :secp256k1

Returns:

• private_key [Tezex.Crypto.PrivateKey.t/0]: private key struct

Example:

iex> Tezex.Crypto.PrivateKey.generate()
%Tezex.Crypto.PrivateKey{...}

@spec get_public_key(t()) :: Tezex.Crypto.PublicKey.t()

Gets the public key associated with a private key

Parameters:

• private_key [Tezex.Crypto.PrivateKey.t/0]: private key struct

Returns:

• public_key [Tezex.Crypto.PublicKey.t/0]: public key struct

Example:

iex> Tezex.Crypto.PrivateKey.get_public_key(private_key)
%Tezex.Crypto.PublicKey{...}
