remove experimental, never-enabled JPAKE code; ok markus@

In the experimental, never-enabled JPAKE code: clear returned digest and
length in hash_buffer() for error cases; could lead to memory corruption
later if EVP_Digest* fails.  Pointed out by Mark Dowd

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@

Revision 1.1 / (download) - annotate - [select for diffs], Tue Nov 4 08:22:13 2008 UTC (15 years, 6 months ago) by djm
Branch: MAIN

Add support for an experimental zero-knowledge password authentication
method using the J-PAKE protocol described in F. Hao, P. Ryan,
"Password Authenticated Key Exchange by Juggling", 16th Workshop on
Security Protocols, Cambridge, April 2008.

This method allows password-based authentication without exposing
the password to the server. Instead, the client and server exchange
cryptographic proofs to demonstrate of knowledge of the password while
revealing nothing useful to an attacker or compromised endpoint.

This is experimental, work-in-progress code and is presently
compiled-time disabled (turn on -DJPAKE in Makefile.inc).
