[higebu]

RSA KEX cipher suites has been marked insecure in go1.22. See https://github.com/golang/go/commit/dc5a0d276bbcd6120325c9e0f9c8fd099fa2b8d6

i just came across this issue too, @higebu I think you also have to add tls.CipherSuites otherwise it will only use the older suites and not the newer ones

@MoltenCan I added tls.CipherSuites. Thanks!
