After years of forewarning, disable the RSA/SHA-1 signature algorithm by default. It is feasible to create colliding SHA1 hashes, so we need to deprecate its use. RSA/SHA-256/512 remains available and will be transparently selected instead of RSA/SHA1 for most SSH servers released in the last five+ years. There is no need to regenerate RSA keys. The use of RSA/SHA1 can be re-enabled by adding "ssh-rsa" to the PubkeyAcceptedAlgorithms directives on the client and server. ok dtucker deraadt

openssh-7.9 accidentally reused the server's algorithm lists in the client for KEX, ciphers and MACs. The ciphers and MACs were identical between the client and server, but the error accidentially disabled the diffie-hellman-group-exchange-sha1 KEX method. This fixes the client code to use the correct method list, but because nobody complained, it also disables the diffie-hellman-group-exchange-sha1 KEX method.

Improve strictness and control over RSA-SHA2 signature types: In ssh, when an agent fails to return a RSA-SHA2 signature when requested and falls back to RSA-SHA1 instead, retry the signature to ensure that the public key algorithm sent in the SSH_MSG_USERAUTH matches the one in the signature itself. In sshd, strictly enforce that the public key algorithm sent in the SSH_MSG_USERAUTH message matches what appears in the signature. Make the sshd_config PubkeyAcceptedKeyTypes and HostbasedAcceptedKeyTypes options control accepted signature algorithms (previously they selected supported key types). This allows these options to ban RSA-SHA1 in favour of RSA-SHA2. Add new signature algorithms "rsa-sha2-256-cert-v01@openssh.com" and "rsa-sha2-512-cert-v01@openssh.com" to force use of RSA-SHA2 signatures with certificate keys. feedback and ok markus@

Remove support for pre-authentication compression. Doing compression early in the protocol probably seemed reasonable in the 1990s, but today it's clearly a bad idea in terms of both cryptography (cf. multiple compression oracle attacks in TLS) and attack surface. Moreover, to support it across privilege-separation zlib needed the assistance of a complex shared-memory manager that made the required attack surface considerably larger. Prompted by Guido Vranken pointing out a compiler-elided security check in the shared memory manager found by Stack (http://css.csail.mit.edu/stack/); ok deraadt@ markus@ NB. pre-auth authentication has been disabled by default in sshd for >10 years.

remove 3des-cbc from the client's default proposal; 64-bit block ciphers are not safe in 2016 and we don't want to wait until attacks like sweet32 are extended to SSH. As 3des-cbc was the only mandatory cipher in the SSH RFCs, this may cause problems connecting to older devices using the defaults, but it's highly likely that such devices already need explicit configuration for KEX and hostkeys anyway. ok deraadt, markus, dtucker

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.

Add support for certificate key types for users and hosts. OpenSSH certificate key types are not X.509 certificates, but a much simpler format that encodes a public key, identity information and some validity constraints and signs it with a CA key. CA keys are regular SSH keys. This certificate style avoids the attack surface of X.509 certificates and is very easy to deploy. Certified host keys allow automatic acceptance of new host keys when a CA certificate is marked as trusted in ~/.ssh/known_hosts. see VERIFYING HOST KEYS in ssh(1) for details. Certified user keys allow authentication of users when the signing CA key is marked as trusted in authorized_keys. See "AUTHORIZED_KEYS FILE FORMAT" in sshd(8) for details. Certificates are minted using ssh-keygen(1), documentation is in the "CERTIFICATES" section of that manpage. Documentation on the format of certificates is in the file PROTOCOL.certkeys feedback and ok markus@

Add a new MAC algorithm for data integrity, UMAC-64 (not default yet, must specify umac-64@openssh.com). Provides about 20% end-to-end speedup compared to hmac-md5. Represents a different approach to message authentication to that of HMAC that may be beneficial if HMAC based on one of its underlying hash algorithms is found to be vulnerable to a new attack. http://www.ietf.org/rfc/rfc4418.txt in conjunction with and OK djm@

add support for RSA to SSH2. please test. there are now 3 types of keys: RSA1 is used by ssh-1 only, RSA and DSA are used by SSH2. you can use 'ssh-keygen -t rsa -f ssh2_rsa_file' to generate RSA keys for SSH2 and use the RSA keys for hostkeys or for user keys. SSH2 RSA or DSA keys are added to .ssh/authorised_keys2 as before. IdentityFile2, HostDsaKey and DSAAuthentication are obsolete. you can use multiple IdentityFile and HostKey for all types of keys. the option DSAAuthentication is replaced by PubkeyAuthetication.
