To configure your GitHub account to use your new (or existing) GPG key, you'll also need to add it to your GitHub account.

Before adding a new GPG key to your GitHub account, you should have:

Supported GPG key algorithms

GitHub supports several GPG key algorithms. If you try to add a key generated with an unsupported algorithm, you may encounter an error.

  • RSA
  • ElGamal
  • DSA
  • ECDH
  • ECDSA
  • EdDSA, except Ed25519

When verifying a signature, we extract the signature and attempt to parse its key-id. We match the key-id with keys uploaded to GitHub. Until you upload your GPG key to GitHub, we cannot verify your signatures.
