RSA Asymmetric Cipher

Interface to RSA cipher and signature algorithm

pyflocker.ciphers.interfaces.RSA.generate(bits: int, e: int = 65537, *, backend: Backends | None = None) → BaseRSAPrivateKey[source]

Generate a private key with given key modulus bits and public exponent e (default 65537). Recommended size of bits > 1024.

Parameters:

  • bits – The bit length of the RSA key.

  • e – The public exponent value. Default is 65537.

Keyword Arguments:

backend – The backend to use. It must be a value from Backends.

Returns:

The RSA private key.

pyflocker.ciphers.interfaces.RSA.load_public_key(data: bytes, *, backend: Backends | None = None) → BaseRSAPublicKey[source]

Loads the public key and returns a Key interface.

Parameters:

data – The public key (a bytes-like object) to deserialize.

Keyword Arguments:

backend – The backend to use. It must be a value from Backends.

Returns:

The RSA public key.

pyflocker.ciphers.interfaces.RSA.load_private_key(data: bytes, passphrase: bytes | None = None, *, backend: Backends | None = None) → BaseRSAPrivateKey[source]

Loads the private key and returns a Key interface.

If the private key was not encrypted duting the serialization, passphrase must be None, otherwise it must be a bytes object.

Parameters:

  • data – The private key (a bytes-like object) to deserialize.

  • passphrase – The passphrase that was used to encrypt the private key. None if the private key was not encrypted.

Keyword Arguments:

backend – The backend to use. It must be a value from Backends.

Returns:

The RSA private key.
