pass negotiated signing algorithm though to sshkey_verify() and check that the negotiated algorithm matches the type in the signature (only matters for RSA SHA1/SHA2 sigs). ok markus@ OpenBSD-Commit-ID: 735fb15bf4adc060d3bee9d047a4bcaaa81b1af9

Switch to recallocarray() for a few operations. Both growth and shrinkage are handled safely, and there also is no need for preallocation dances. Future changes in this area will be less error prone. Review and one bug found by markus Upstream-ID: 822d664d6a5a1d10eccb23acdd53578a679d5065

fix three bugs in KRL code related to (unused) signature support: verification length was being incorrectly calculated, multiple signatures were being incorrectly processed and a NULL dereference that occurred when signatures were verified.

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.

deprecate key_load_private_pem() and sshkey_load_private_pem() interfaces. Refactor the generic key loading API to not require pathnames to be specified (they weren't really used). Fixes a few other things en passant: Makes ed25519 keys work for hostbased authentication (ssh-keysign previously used the PEM-only routines). Fixes key comment regression bz#2306: key pathnames were being lost as comment fields. ok markus@

fix KRL generation when multiple CAs are in use We would generate an invalid KRL when revoking certs by serial number for multiple CA keys due to a section being written out twice. Also extend the regress test to catch this case by having it produce a multi-CA KRL. Reported by peter AT pean.org

[krl.c] fix bug in KRL generation: multiple consecutive revoked certificate serial number ranges could be serialised to an invalid format. Readers of a broken KRL caused by this bug will fail closed, so no should-have-been-revoked key will be accepted.

[auth.c key.c key.h ssh-keygen.1 ssh-keygen.c sshd_config.5] [krl.c krl.h PROTOCOL.krl] add support for Key Revocation Lists (KRLs). These are a compact way to represent lists of revoked keys and certificates, taking as little as a single bit of incremental cost to revoke a certificate by serial number. KRLs are loaded via the existing RevokedKeys sshd_config option. feedback and ok markus@
