Method Details

newPrivateKeySigner

public static Signer newPrivateKeySigner(PrivateKey privateKey)

Create a new signer that uses the supplied private key for signing. The Identities class provides static methods to create a PrivateKey object from PEM-format data.

Currently supported private key types are:

• ECDSA.
• Ed25519.

Note that the Sign implementations have different expectations on the input data supplied to them.

The ECDSA signers operate on a pre-computed message digest, and should be combined with an appropriate hash algorithm. P-256 is typically used with a SHA-256 hash, and P-384 is typically used with a SHA-384 hash.

The Ed25519 signer operates on the full message content, and should be combined with a NONE (or no-op) hash implementation to ensure the complete message is passed to the signer.

Parameters:

privateKey - A private key.

Returns:

A signer implementation.
