      • nativeGetAlgorithmDescription

        public static int nativeGetAlgorithmDescription​(byte[] algorithmBytes)
        On a device an algorithm id is a constant that the LLAPI returns, and Managed Code never closes it. The mock therefore encodes it as an index in ALGORITHM_NAMES, and rebuilds the key factory on each use, so that a lookup allocates nothing.
        Parameters:
        algorithmBytes - Null terminated string that describes the algorithm
        Returns:
        algorithm ID on success or -1 on error.

      • nativeGetPrivateKeyData

        public static int nativeGetPrivateKeyData​(int nativeAlgorithmId,
                                          byte[] formatBytes,
                                          byte[] encodedKey,
                                          int encodedKeyLength)
        Parameters:
        nativeAlgorithmId - the algorithm ID
        formatBytes - the format of the encoded key
        encodedKey - the encoded private key
        encodedKeyLength - the length of the encoded key
        Returns:
        the registered native resource id, or -1 on error.

      • nativeGetPublicKeyData

        public static int nativeGetPublicKeyData​(int nativeAlgId,
                                         byte[] formatBytes,
                                         byte[] encodedKey,
                                         int encodedKeyLength)

      • nativeGetPublicKeyCloseId

        public static int nativeGetPublicKeyCloseId​(int nativeAlgorithmId)
        Gets the id of the native close function.
        Parameters:
        nativeAlgorithmId - the algorithm ID
        Returns:
        the id of the static native close function
        Throws:
        ej.sni.NativeException - on error

      • nativeGetPrivateKeyCloseId
