    extends Signature
    Implements the JDK Signature interface needed for RAW RSA signature generation and verification using OpenSSL.
    • Method Detail

      • engineUpdate

        protected void engineUpdate(byte input)
        Description copied from class: SignatureSpi
        Updates the data to be verified or to be signed, using the specified byte.
        Specified by:
        engineUpdate in class SignatureSpi
        Parameters:
        input - the byte to update with.
      • engineUpdate

        protected void engineUpdate(byte[] input,
                        int offset,
                        int len)
        Description copied from class: SignatureSpi
        Updates the data to be verified or to be signed, using the given byte[], starting form the specified index for the specified length.
        Specified by:
        engineUpdate in class SignatureSpi
        Parameters:
        input - the byte array to update with.
        offset - the start index in b of the data.
        len - the number of bytes to use.
      • engineInitVerify

        protected void engineInitVerify(PublicKey publicKey)
                                 throws InvalidKeyException
        Description copied from class: SignatureSpi
        Initializes this SignatureSpi instance for signature verification, using the public key of the identity whose signature is going to be verified.
        Specified by:
        engineInitVerify in class SignatureSpi
        Parameters:
        publicKey - the public key.
        Throws:
        InvalidKeyException - if publicKey is not valid.
      • engineSign

        protected byte[] engineSign()
                             throws SignatureException
        Description copied from class: SignatureSpi
        Generates and returns the signature of all updated data.

        This SignatureSpi instance is reset to the state of its last initialization for signing and thus can be used for another signature from the same identity.

        Specified by:
        engineSign in class SignatureSpi
        Returns:
        the signature of all updated data.
        Throws:
        SignatureException - if this SignatureSpi instance is not initialized properly.
      • engineVerify

        protected boolean engineVerify(byte[] sigBytes)
                                throws SignatureException
        Description copied from class: SignatureSpi
        Indicates whether the given sigBytes can be verified using the public key or a certificate of the signer.

        This SignatureSpi instance is reset to the state of its last initialization for verifying and thus can be used to verify another signature of the same signer.

        Specified by:
        engineVerify in class SignatureSpi
        Parameters:
        sigBytes - the signature to verify.
        Returns:
        true if the signature was verified, false otherwise.
        Throws:
        SignatureException - if this SignatureSpi instance is not initialized properly.
