Module ring::aead::chacha20_poly1305_openssh [−][src]
The chacha20-poly1305@openssh.com AEAD-ish construct.
This should only be used by SSH implementations. It has a similar, but
different API from ring::aead because the construct cannot use the same
API as ring::aead due to the way the construct handles the encrypted
packet length.
The concatenation of a and b is denoted a||b. K_1 and K_2 are defined
in the chacha20-poly1305@openssh.com specification. packet_length,
padding_length, payload, and random padding are defined in
RFC 4253. The term plaintext is used as a shorthand for
padding_length||payload||random padding.
