WebApr 4, 2024 · priv is the private key to sign the CSR with, and the corresponding public key will be included in the CSR. It must implement crypto.Signer and its Public() method must return a *rsa.PublicKey or a *ecdsa.PublicKey or a ed25519.PublicKey. (A *rsa.PrivateKey, *ecdsa.PrivateKey or ed25519.PrivateKey satisfies this.) ECDSA sometimes causes confusion when interop'ing with other libraries like OpenSSL and Java. The problem usually reduces to OpenSSL and Java use an ASN.1/DER signature format, and Crypto++ uses a IEEE P1363 format.
