crypto/ssh: return error from NewClientConn with "%w"

2023-08-28T16:27:12Z

By returning error with %w, the caller can check and convert the error using errors.As, for example to knownhosts.KeyError. Change-Id: I0529e2e935cd8075f87aa6f6049cee3323f82c06

ssh: ignore invalid MACs and KEXs just like we do for ciphers

2023-07-31T15:35:32Z

Tighter validation could cause backwards incompatibility issues, eg configurations with valid and invalid MACs, KEXs, ciphers currently work if a supported algorithm is negotiated and that's also the scenario of removing support for an existing algorithm.

internal/wycheproof: skip all tests in short test mode

2023-07-18T15:17:25Z

The testdata for this package is around 8 MB and downloaded dynamically via 'go mod download' from its canonical source rather than being copied to this repository. We're moving towards disallowing all network use in short test mode, including proxy.golang.org, so add a corresponding test skip. Needing to lookup a go test flag is unfortunate, but I don't know of a less bad available option while the test does the download in TestMain. On balance, it becomes viable to no longer disable the checksum database since the test will only run on builders that permit internet use and so sum.golang.org should just work.

ssh: prefer sha256 based RSA key algorithms

2023-07-14T16:27:34Z

sha256 is more optimized than sha512 in Go and is secure enough so prefer sha256 over sha512.
