NaCl::AEAD::XChaCha20Poly1305

Inherits NaCl::AEAD::Base / Reference / Object

The XChaCha20-Poly1305 construction can safely encrypt a practically unlimited number of messages with the same key, without any practical limit to the size of a message (up to ~ 2^64 bytes).

As an alternative to counters, its large nonce size (192-bit) allows random nonces to be safely used.

For this reason, and if interoperability with other libraries is not a concern, this is the recommended AEAD construction.

For documentation on all AEAD methods, see AEAD::Base.
