OpenSSL::PKey::PKeyError: EVP_DigestVerifyInit: invalid digest

[HoneyryderChuck]

In the httpx test suite, I've been monitoring this truffleruby issue for a while, which still manifests after the upgrade to 23.1.0. FWIW I was able to reduce it to plain net-ssh-gateway example (ssh parameters relate to the ssh server used in the tests):

require "uri"
require "net/ssh/gateway"

ssh_uri = URI("ssh://sshproxy:22")

ssh_options = {
  auth_methods: %w[publickey],
  host_key: "ssh-rsa",
  keys: %w[test/support/ssh/ssh_host_ed25519_key]
}

gateway = Net::SSH::Gateway.new(ssh_uri.host, "root", ssh_options)

puts "done"
# works in ruby 3.2, breaks with truffleruby 23.1.0

Thank you for the report, we'll try to take a look.
I might wait after #3118 as that might possibly solve it.
