Can ssh-keygen be seeded to generate the same key?

Is it possible to seed ssh-keygen with a fixed string so that it consistently generates the same keypair?

security ssh

  1. No. You can pick certain criteria which may reduce the randomness of the generated key, but the generation process is not a simple as picking a particular seed from which the keys are generated.

  2. You can, just not with the default ssh-keygen. I personally use ssh-key-generator

  3. Here is another cool tool for generating deterministic ssh keys: cornfeedhobo/ssh-keydgen, it's written on go
