on RHEL 9 OpenSSH does not support DSA keys and RSA keys with size less than 2048 bits, furthermore signing with ssh-rsa (SHA-1 signatures) and ssh-dss is not allowed, therefore: 1) replaced the 1024-bit RSA key used in the test with a new 2048-bit one 2) removed DSA key from itegration tests 3) allowed signature errors using ssh-rsa in agent integration tests, we also check SHA-2 variants that are not skipped Fixes golang/go#65581 Change-Id: I54bf997b61ef4d91d38eb624275737ba7291bb20 Reviewed-on: https://go-review.googlesource.com/c/crypto/+/562755 Reviewed-by: Roland Shoemaker <roland@golang.org> Reviewed-by: David Chase <drchase@google.com> Reviewed-by: Filippo Valsorda <filippo@golang.org> Auto-Submit: Nicola Murino <nicola.murino@gmail.com> LUCI-TryBot-Result: Go LUCI <golang-scoped@luci-project-accounts.iam.gserviceaccount.com>
