Implement server-side support for sk-ecdsa U2F-backed keys (#142)
* Implement server-side support for sk-ecdsa U2F-backed keys
* Fix out-of-bounds read on normal ecdsa-sha2-[identifier] keys
* Fix one more potential out-of-bounds read
* Check if nistp256 curve is used in sk-ecdsa-sha2- key
It's the only allowed curve per PROTOCOL.u2f specification
* Implement server-side support for sk-ed25519 FIDO2-backed keys
* Keys with type sk-* make no sense as host keys, so they should be
disabled
* fix typo
* Make sk-ecdsa call buf_ecdsa_verify
This reduces code duplication, the SK code just handles the
different message format.
* Reduce sk specific code
The application id can be stored in signkey, then we don't need
to call sk-specific functions from svr-authpubkey
* Remove debugging output, which causes compilation errors with DEBUG_TRACE disabled
* Proper cleanup of sk_app

This file is out of date - it remains here in case it is still of use. The basic naming convention is svr- and cli- for seperate parts, then common- for common parts. Some files have no prefix. A brief rundown on which files do what, and their corresponding sections in the IETF drafts. The .c files usually have corresponding .h files. Transport layer draft-ietf-secsh-transport-16.txt =============== session.c Contains the main select() loop, and handles setting up/closing down ssh connections algo.c Framework for handling various ciphers/hashes/algos, and choosing between the lists of client/server preferred ones kex.c Key exchange routines, used at startup to negotiate which algorithms to use, and also to obtain session keys. This also runs when rekeying during the connection. packet.c Handles the basic packet encryption/decryption, and switching to the appropriate packet handlers. Called from session.c's main select loop. service.c Handles service requests (userauth or connection) Authentication draft-ietf-secsh-userauth-17.txt ============== auth.c General auth handling, including user checking etc, passes different auth types to auth{passwd,pubkey} authpasswd.c Handles /etc/passwd or /etc/shadow auth authpubkey.c Handles ~/.ssh/authorized_keys auth Connection draft-ietf-secsh-connect-17.txt ========== channel.c Channel handling routines - each shell/tcp conn/agent etc is a channel. chansession.c Handles shell/exec requests sshpty.c From OpenSSH, allocates PTYs etc termcodes.c Mapping of POSIX terminal codes to SSH terminal codes loginrec.c From OpenSSH, handles utmp/wtmp logging x11fwd.c Handles X11 forwarding agentfwd.c Handles auth-agent forwarding requests localtcpfwd.c Handles -L style tcp forwarding requests, setting up the listening port and also handling connections to that port (and subsequent channels) Program-related =============== dbmulti.c Combination binary chooser main() function dbutil.c Various utility functions, incl logging, memory etc dropbearconvert.c Conversion from dropbear<->openssh keys, uses keyimport.c to do most of the work dropbearkey.c Generates keys, calling gen{dss,rsa} keyimport.c Modified from PuTTY, converts between key types main.c dropbear's main(), handles listening, forking for new connections, child-process limits runopts.c Parses commandline options options.h Compile-time feature selection config.h Features selected from configure debug.h Compile-time selection of debug features includes.h Included system headers etc Generic Routines ================ signkey.c A generic handler for pubkeys, switches to dss or rsa depending on the key type rsa.c RSA asymmetric crypto routines dss.c DSS asymmetric crypto routines ed25519.c Ed25519 asymmetric crypto routines gened25519.c Ed25519 key generation gendss.c DSS key generation genrsa.c RSA key generation bignum.c Some bignum helper functions queue.c A queue, used to enqueue encrypted packets to send random.c PRNG, based on /dev/urandom or prngd atomicio.c From OpenSSH, does `blocking' IO on non-blocking fds buffer.c Buffer-usage routines, with size checking etc vim:set ts=8:
