About addition of GPG keys to your account
To sign commits associated with your account on GitHub, you can add a public GPG key to your personal account. Before you add a key, you should check for existing keys. If you don't find any existing keys, you can generate and copy a new key. For more information, see "Checking for existing GPG keys" and "Generating a new GPG key."
You can add multiple public keys to your account on GitHub. 由任何相应私钥签名的提交将显示为已验证。 如果删除公钥,则由相应私钥签名的任何提交将不再显示为已验证。
To verify as many of your commits as possible, you can add expired and revoked keys. If the key meets all other verification requirements, commits that were previously signed by any of the corresponding private keys will show as verified and indicate that their signing key is expired or revoked.
支持的 GPG 密钥算法
GitHub 支持多种 GPG 密钥算法。 如果您尝试添加使用不支持的算法生成的密钥,可能会发生错误。
- RSA
- ElGamal
- DSA数字签名算法
- ECDH
- ECDSA
- EdDSA
When verifying a signature, GitHub extracts the signature and attempts to parse its key ID. The key ID is then matched with keys added to GitHub. Until a matching GPG key is added to GitHub, it cannot verify your signatures.
