| | | | | | | | Disables and removes dependency on OpenSSL. Many features don't work and the set of crypto options is greatly restricted. This will only work on system with native arc4random or /dev/urandom. Considered highly experimental for now.

| | | | | | | | | | [cipher.c cipher.h kex.c kex.h kexgexc.c] Add a special case for the DH group size for 3des-cbc, which has an effective strength much lower than the key size. This causes problems with some cryptlib implementations, which don't support group sizes larger than 4k but also don't use the largest group size it does support as specified in the RFC. Based on a patch from Petr Lautrbach at Redhat, reduced by me with input from Markus. ok djm@ markus@

| | | | | | | | | | | | | | | [kex.c kex.h kexecdh.c key.c key.h monitor.c ssh-ecdsa.c] 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@

Only the mandatory sections of RFC5656 are implemented, specifically the three REQUIRED curves nistp256, nistp384 and nistp521 and only ECDH and ECDSA.

| | | | | | | [openbsd-compat/sha2.h openbsd-compat/openbsd-compat.h] [openbsd-compat/sha2.c] First stab at portability glue for SHA256 KEX support, should work with libc SHA256 support or OpenSSL EVP_sha256 if present

| | | | | | | | [kex.c kex.h monitor.c myproposal.h ssh-keyscan.c sshconnect2.c sshd.c] Implement the diffie-hellman-group-exchange-sha256 key exchange method using the SHA256 code in libc (and wrapper to make it into an OpenSSL EVP), interop tested against CVS PuTTY NB. no portability bits committed yet

| | | | | | | | | | | [kex.c kex.h myproposal.h packet.c packet.h servconf.c session.c] [sshconnect2.c sshd.c sshd_config sshd_config.5] add a new compression method that delays compression until the user has been authenticated successfully and set compression to 'delayed' for sshd. this breaks older openssh clients (< 3.5) if they insist on compression, so you have to re-enable compression in sshd_config. ok djm@
