Supported Key Types
Prompt currently supports keys of the following types for both host key verification and client key exchange:
in both PEM and OpenSSH formats where applicable.
If Prompt detects a public key (ex.,
id_rsa.pub) or anything that doesn’t exactly match the format of supported private keys, it won’t offer to let you import from the clipboard. If you already have a PuTTY key (in the PPK format), you can convert it by following these instructions under the Dealing with Private Keys in Other Formats section, then import the resulting OpenSSH private key into Prompt.
