The subpages of https://wikitech.wikimedia.org/wiki/Help:SSH_Fingerprints list the server fingerprints using md5 hash. The sha256 hashes (used by default in recent openssh versions) should be also included.
For instance, the fingerprints for bastion.wmflabs.org are:
```
ssh_host_dsa_key.pub
1024 MD5:25:aa:15:a6:9b:17:b7:b5:08:87:27:10:f7:b8:dd:52 root@bastion-01 (DSA)
1024 SHA256:GDabrrv0tiP0GDeijmU/wV+/ctIPMeFboSgQwySpQ9w root@bastion-01 (DSA)
ssh_host_ecdsa_key.pub
256 MD5:22:3e:0a:08:8a:30:30:3e:d1:45:94:d9:17:bb:19:70 root@bastion-01 (ECDSA)
256 SHA256:s+xuLo91PcVIFcFdxPQC7IXgJ2nYxaXcqa7bKE7/ufA root@bastion-01 (ECDSA)
ssh_host_ed25519_key.pub
256 MD5:5c:4d:7d:d0:85:7b:28:2d:95:a7:8a:33:e8:c4:a7:19 root@bastion-01 (ED25519)
256 SHA256:IpbbkMII0QK+vUiai6dvQWh5U2+IwH0+xXq2VS9b41E root@bastion-01 (ED25519)
ssh_host_rsa_key.pub
2048 MD5:20:1d:1a:b5:49:4e:4e:d4:dd:b1:06:4e:de:f4:da:44 root@bastion-01 (RSA)
2048 SHA256:fz9h4yOn113giipgabMz6SXK4mD0kCAXGUAC8ibbhlg root@bastion-01 (RSA)
```
that should be saved in https://wikitech.wikimedia.org/wiki/Help:SSH_Fingerprints/bastion.wmflabs.org
A wikitech sysop needs to gather the sha256 hashes and fill those pages.
