class Sodium::Cipher::SecretStream::XChaCha20Poly1305
Overview
This class mimicks the OpenSSL::Cipher interface with minor differences.
- every .update is it's own authenticated message. Unlike OpenSSL this class doesn't buffer data. You must handle the framing yourself.
- .header must be called for encryption before calling .update
- .header= must be called for decryption with the data returned from .header before calling .update
- A tag may be set before encrypting and is set after calling .update when decrypting.
- .additional may be set before encrypting and must be set before decrypting.
See spec/sodium/cipher/secret_stream_spec.cr for examples on how to use this class.
