Hello folks, I am new here, so please be gentle :), and any help will be appreciated. Essentially what I am trying to do is, to use Jsch ( the java implementation of SSH client). it has support for Public key based authentication. Since there is a requirement for FIPS enablement, we are trying to use the Algorithm SHA256withRSA, instead of SHA1withRSA. When the code tries to verify the

Hello, I have some users that connect to a server with their DSA key that is of type ssh-dss. I'm migrating (installing as new) the server where they connect to CentOS 8 + updates. I was not able to connect with the keys to this new server even after having added, as found in several internet pages, this directive at the end of /etc/ssh/sshd_config of the CentOS 8 server: # Accept also DSA

Hello. I am running OpenSSH 7.9p1 on my client and server. ssh-keyscan shows the server has ssh-rsa, ssh-ed25519, and ecdsa-sha2-nistp256 host keys. My /etc/ssh/ssh_known_hosts file contains the server's ssh-ed25519 host key. When I try to SSH to the server I get this error: @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!

Hi, Following the fix [1] being released on 7.5, now SHA2 RSA signature methods work properly. On the other hand it is still not possible to disable SHA1 RSA alone (as an example, as SHA2-256 or SHA2-512 could also potentially be not desirable), where it is considered insecure or undesirable. I am proposing to add a mechanism, and happy to submit a patch, to enable selection of the Hashes

I am trying to understand the details of the deprecation notice. Because I am getting people asking me questions. And I don't know the answer. Therefore I am pushing the boulder uphill and asking here. :-) Damien Miller wrote: > Future deprecation notice > ========================= > > It is now possible[1] to perform chosen-prefix attacks against the > SHA-1 algorithm for

So I add the line PubkeyAcceptedKeyTypes +ssh-dss to my opensshd_config file. When I restart sshd, I am told that May 11 09:33:14 pickles systemd: Started OpenSSH Server Key Generation.

With the upcoming deprecation of ssh-rsa I was trying to see what keys my version of OpenSSH ( 7.8p1 ) supports. I noticed that "ssh -Q key" does not actually list the suggested algorithms to transition to ( rsa-sha2-256 and rsa-sha2-512 ) even though they are supported. Looking through the code, it looks like an issue with the arguments passed to sshkey_alg_list in ssh.c where it should
