DeriveArgonKey generates a 32-bit cryptographic key using the Argon2id algorithm.

DeriveLoginKey derives a login key from the given key encryption key.

EncryptChaCha20poly1305 encrypts the given data using the ChaCha20-Poly1305 algorithm.

TagFinal indicates that the message marks the end of the stream, and erases the secret key used to encrypt the previous sequence.

TagMessage the most common tag, that doesn't add any information about the nature of the message.

TagPush indicates that the message marks the end of a set of messages, but not the end of the stream.

TagRekey "forget" the key used to encrypt this message and the previous ones, and derive a new secret key.
