                     throws java.security.SignatureException
        Specified by:
        engineSign in class java.security.SignatureSpi
        Throws:

                        throws java.security.SignatureException
        Specified by:

      • applyParams

        protected final void applyParams​(boolean prehash,
                                 byte[] context)
                          throws java.security.InvalidAlgorithmParameterException
        Apply the RFC 8032 instance selectors. Parameters must be set before initSign / initVerify (the signer that consumes them is built at init time), matching the SunEC EdDSA behaviour.
        Throws:
        java.security.InvalidAlgorithmParameterException

      • checkCurve

        protected final void checkCurve​(java.lang.String curveName)
                         throws java.security.InvalidAlgorithmParameterException
        When the spec names a curve, reject it if it cannot match a single-algorithm SPI (the per-curve Ed25519 / Ed448 SignatureSpi subclasses). The generic EdDSA SPI (algorithm == null) defers the curve to the key.
        Throws:
        java.security.InvalidAlgorithmParameterException
