Because of this, we use the public domain + reference implementation instead of the crypto backends, just like + OpenSSH does. + + We've been holding this one for a few years. We were about to upstream + it around the same time as aes128gcm landed upstream, and the two + changes were completely incompatible. Honestly, it took me weeks to + reconcile these two implementations, and it could be much better. + + Our original implementation changed every crypt method to decrypt the + entire message at once. the AESGCM implementation instead went with this + firstlast design, where a firstlast paramater indicates whether this is + the first or last call to the crypt method for each message. That added + a lot of bookkeeping overhead, and wasn't compatible with the chacha + public domain implementation. + + As far as I could tell, OpenSSH uses the technique of decrypting the + entire message in one go, and doesn't have anything like firstlast. + However, I could not get out aes128gcm implementation to work that way, + nor could I get the chacha implementation to work with firstlast, so I + split it down the middle and let each implementation work differently. + It's kind of a mess, and probably should be cleaned up, but I don't have + the time to spend on it anymore, and it's probably better to have + everything upstream. + + Fixes #584 + Closes #1426 + +- tidy-up: do/while formatting + + Also fix an indentation and delete empty lines. + + Closes #1440 + +- wolfssl: drop header path hack + + The wolfSSL OpenSSL headers reside in `wolfssl/openssl/*.h`. + + Before this patch the wolfSSL OpenSSL compatibilty header includes were + shared with the native OpenSSL codepath, and used `openssl/*h`.

These are implemented for recent versions of OpenSSL only. + + The ciphers work differently than most previous ones in two big areas: + the cipher includes its own integrated MAC, and the packet length field + in the SSH frame is left unencrypted. The code changes necessary are + gated by flags in the LIBSSH2_CRYPT_METHOD configuration structure. + + These differences mean that both the first and last parts of a block + require special handling during encryption. The first part is where the + packet length field is, which must be kept out of the encryption path + but in the authenticated part (as AAD). The last part is where the + Authentication Tag is found, which is calculated and appended during + encryption or removed and validated on decryption. As encryption/ + decryption is performed on each packet in a loop, one block at a time, + flags indicating when the first and last blocks are being processed are + passed down to the encryption layers. + + The strict block-by-block encryption that occurs with other protocols is + inappropriate for AES-GCM, since the packet length shifts the first + encrypted byte 4 bytes into the block. Additionally, the final part of + the block must contain the AES-GCM's Authentication Tag, so it must be + presented to the lower encryption layer whole. These requirements mean + added code to consolidate blocks as they are passed down. + + When AES-GCM is negotiated as the cipher, its built-in MAC is + automatically used as the SSH MAC so further MAC negotiation is not + necessary. The SSH negotiation is skipped when _libssh2_mac_override() + indicates that such a cipher is in use.
