OpenJDK 27 · java.security.spec.EdECPrivateKeySpec · APIdia, the JavaDoc alternative

A class representing elliptic curve private keys as defined in RFC 8032: Edwards-Curve Digital Signature Algorithm (EdDSA), including the curve and other algorithm parameters. The private key is a bit string represented using a byte array. This class only supports bit string lengths that are a multiple of 8.
