move client/server SSH-* banners to buffers under ssh->kex and factor out the banner exchange. This eliminates some common code from the client and server. Also be more strict about handling \r characters - these should only be accepted immediately before \n (pointed out by Jann Horn). Inspired by a patch from Markus Schmidt. (lots of) feedback and ok markus@

Introduce digest API and use it to perform all hashing operations rather than calling OpenSSL EVP_Digest* directly. Will make it easier to build a reduced-feature OpenSSH without OpenSSL in future; feedback, ok markus@

ECDH/ECDSA compliance fix: these methods vary the hash function they use (SHA256/384/512) depending on the length of the curve in use. The previous code incorrectly used SHA256 in all cases. This fix will cause authentication failure when using 384 or 521-bit curve keys if one peer hasn't been upgraded and the other has. (256-bit curve keys work ok). In particular you may need to specify HostkeyAlgorithms when connecting to a server that has not been upgraded from an upgraded client. ok naddy@
Revision 1.1 / (download) - annotate - [select for diffs], Tue Aug 31 11:54:45 2010 UTC (13 years, 8 months ago) by djm
Branch: MAIN
Implement Elliptic Curve Cryptography modes for key exchange (ECDH) and host/user keys (ECDSA) as specified by RFC5656. ECDH and ECDSA offer better performance than plain DH and DSA at the same equivalent symmetric key length, as well as much shorter keys. Only the mandatory sections of RFC5656 are implemented, specifically the three REQUIRED curves nistp256, nistp384 and nistp521 and only ECDH and ECDSA. Point compression (optional in RFC5656 is NOT implemented). Certificate host and user keys using the new ECDSA key types are supported. Note that this code has not been tested for interoperability and may be subject to change. feedback and ok markus@
