2022-03-14ssh: deprecate and replace SigAlgo constantsFilippo Valsorda
RFC 8332, Section 2 sets up two overlapping namespaces: public key formats and public key algorithms. * The formats are what we currently have KeyAlgo constants for, and they appear in PublicKey.Type. * The algorithms are the set of both KeyAlgo and SigAlgo constants, and they appear in Signature.Format (amongst other places). This is incoherent, because that means Signature.Format can be both a KeyAlgo (like KeyAlgoECDSA256) or a SigAlgo (like SigAlgoRSASHA2256). One solution would be to duplicate all the KeyAlgo constants into the SigAlgo namespace, but that would be confusing because applications are currently using KeyAlgos where they'd be supposed to use the new SigAlgos (while we can't deprecate the KeyAlgos because they are still necessary for the PublicKey.Type namespace). Instead, drop the separate namespaces, and use KeyAlgos throughout. There are simply some KeyAlgos that can't be a PublicKey.Type. Take the opportunity to fix the stuttering SHA22565/SHA2512 names. It's totally ok to call those hashes SHA-256 and SHA-512 without the family infix.

2019-11-28ssh/agent: fix TestServerResponseTooLarge on Plan 9Fazlul Shahriar
First, modify the test to report a better error by waiting for the Marshal+Write goroutine to finish before returning from the test. If we return too early, a failure inside that goroutine can generate a panic. Second, we workaround plan9 not returning the actual number of bytes written on the connection in case of a hangup (due to closed connection). I've verified that syscall.Pwrite returns -1 on hangup in this particular case even when some data did get written.

2018-10-29ssh: support SSH agent signature flags and custom extensionsIan Haken
This commit implements two new features. To preserve backwards compatibility the new methods are added to an `ExtendedAgent` interface which extends `Agent`. The client code implements `ExtendedAgent` (which extends Agent) so you can call these additional methods against SSH agents such as the OpenSSH agent. The ServeAgent method still accepts Agent but will attempt to upcast the agent to `ExtendedAgent` as needed, so if you supply an ExtendedAgent implementation you can implement these additional methods (which keyring does). The first feature is supporting the standard flags that can be passed to SSH Sign requests, requesting that RSA signatures use SHA-256 or SHA-512. See section 4.5.1 of the SSH agent protocol draft: https://tools.ietf.org/html/draft-miller-ssh-agent-02 The second feature is supporting calling custom extensions from clients and implementing custom extensions from servers. See section 4.7 of the SSH agent protocol draft: https://tools.ietf.org/html/draft-miller-ssh-agent-02 Change-Id: I0f74feb893762c27e921ec37604d3a46434ee6ef GitHub-Last-Rev: 2e23fd01c0e95b664e8507682f0bd5bd61d4c146 GitHub-Pull-Request: golang/crypto#53 Reviewed-on: https://go-review.googlesource.com/c/123955 Reviewed-by: Han-Wen Nienhuys <hanwen@google.com> Run-TryBot: Han-Wen Nienhuys <hanwen@google.com> TryBot-Result: Gobot Gobot <gobot@golang.org>

Dialing the 0.0.0.0 address (as returned by net.Addr().String() for a net.Listen("tcp", ":1") address) is not yet guaranteed to work. It's currently OS-dependent. For some reason it works on Go 1.8+, but it hasn't yet been defined to work reliably. Fix the tests for now (since we need to support older Go releases), even if this might work in the future.

2017-03-30ssh: require host key checking in the ClientConfigHan-Wen Nienhuys
This change breaks existing behavior. Before, a missing ClientConfig.HostKeyCallback would cause host key checking to be disabled. In this configuration, establishing a connection to any host just works, so today, most SSH client code in the wild does not perform any host key checks. This makes it easy to perform a MITM attack: * SSH installations that use keyboard-interactive or password authentication can be attacked with MITM, thereby stealing passwords. * Clients that use public-key authentication with agent forwarding are also vulnerable: the MITM server could allow the login to succeed, and then immediately ask the agent to authenticate the login to the real server. * Clients that use public-key authentication without agent forwarding are harder to attack unnoticedly: an attacker cannot authenticate the login to the real server, so it cannot in general present a convincing server to the victim. Now, a missing HostKeyCallback will cause the handshake to fail. This change also provides InsecureIgnoreHostKey() and FixedHostKey(key) as ready made host checkers. A simplistic parser for OpenSSH's known_hosts file is given as an example. This change does not provide a full-fledged parser, as it has complexity (wildcards, revocation, hashed addresses) that will need further consideration. When introduced, the host checking feature maintained backward compatibility at the expense of security. We have decided this is not the right tradeoff for the SSH library.
