An interesting mistake I made with a (Go) SSH client API

=> ↺ An interesting mistake I made with a (Go) SSH client API

You can criticize the API here for being stringly typed, but I think that it's actually natural to do something like that, especially if you're initially designing the API in the old world, before "rsa-sha2-256" and when "ssh-rsa" was the (only) key algorithm you used with 'ssh-rsa' keys. In that world, the official names of key types and key algorithms were the same; making them two separate programming types and forcing people to explicitly convert between them is likely to strike people as perverse. Do you want to write or even have to use a function that converts 'keytype.Ed25519' into 'keyalgo.Ed25519'? Most people are going to say no. Just call it 'Ed25519' and be done.
