Add Ed25519 support (#91)
* Add support for Ed25519 as a public key type
Ed25519 is a elliptic curve signature scheme that offers
better security than ECDSA and DSA and good performance. It may be
used for both user and host keys.
OpenSSH key import and fuzzer are not supported yet.
Initially inspired by Peter Szabo.
* Add curve25519 and ed25519 fuzzers
* Add import and export of Ed25519 keys

This file is out of date - it remains here in case it is still of use.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:
