Utilities

class nacl.utils.EncryptedMessage[source]

A bytes subclass that holds a message that has been encrypted by a SecretBox or Box. The full content of the bytes object is the combined nonce and ciphertext.

nonce: The nonce used during the encryption of the EncryptedMessage.

ciphertext: The ciphertext contained within the EncryptedMessage.

nacl.utils.random(size=32)[source]

Returns a random bytestring with the given size.

Parameters:: size (bytes) – The size of the random bytestring.
Return bytes:: The random bytestring.

nacl.utils.randombytes_deterministic(size, seed, encoder=encoding.RawEncoder)[source]

Returns size number of deterministically generated pseudorandom bytes from a 32 byte seed.

Parameters:

size (bytes) – The size of the random bytestring.
seed (bytes) – The seed for the bytestring. This should be 32 bytes or a TypeError will be thrown.
encoder – The encoder class used to encode the produced bytes.

Return bytes:

The random bytestring.
