ABSTRACT
list of my keys and short usage
I use SSH keys to sign stuff if I need to. The following keys are mine:
| Name | Note | Valid Since | Link | Full Text |
| tropf.pub | default key | 2025 | download | sk-ssh-ed25519@openssh.com AAAAGnNrLXNzaC1lZDI1NTE5QG9wZW5zc2guY29tAAAAIHL3Z0DzGWSReXu23pWZtyxthxT/7kvFok486aAqQXkGAAAABHNzaDo= |
| tropf_secondary.pub | backup key | 2025 | download | sk-ssh-ed25519@openssh.com AAAAGnNrLXNzaC1lZDI1NTE5QG9wZW5zc2guY29tAAAAIIw1Ay9FOHoRrdU2GGlkVxWl/6HkTGvVC0E3Qhw8axGCAAAABHNzaDo= |
By default, you will encounter tropf.pub; however in case I ever lose it the backup key is equally valid as a replacement.
This table lists signatures of keys on each other. Download the signatures using the links in the table, the referenced keys can be retrieved above. Additional keys may appear here to establish their authenticity.
| Signing Key | Signed Key | Signature |
| tropf.pub | tropf_secondary.pub | tropf_secondary.pub.sig |
| tropf_secondary.pub | tropf.pub | tropf.pub.sig |
To sign a file FILE with the SSH key KEY use the following command:
ssh-keygen -Y sign -f KEY -n file FILE
The result will be written into file.name.sig.
› The argument file is the so-called "namespace". It is hard-coded and does not refer to any specific file.
Use this command to validate that the public key KEY.pub created the signature FILE.sig for the file FILE:
ssh-keygen -Y check-novalidate -f KEY.pub -n file -s FILE.sig < FILE
There are two commands in ssh-keygen to check signatures. As verify requires a key database (an extra file with its own format) prefer check-novalidate which only validates a signature against exactly one key.
