chacha_box_ietf

Sealed boxes are designed to anonymously send messages to a recipient given their public key. A message is encrypted using an ephemeral key pair, with the secret key being erased right after the encryption process.

This crate provides sealed boxes using ChaCha20-Poly1305 as AEAD cipher, as described in RFC-8439.
