      boolean sodiumPad​(com.sun.jna.ptr.IntByReference paddedBuffLen, com.sun.jna.Pointer buf, int unpaddedBufLen, int blockSize, int maxBufLen)
      Adds extra padding to a buffer buf whose original size is unpaddedBufLen in order to extend its total length to a multiple of blocksize.
      boolean sodiumUnpad​(com.sun.jna.ptr.IntByReference unpaddedBufLen, com.sun.jna.Pointer buf, int paddedBufLen, int blockSize)
      Computes the original, unpadded length of a message previously padded using sodiumPad(IntByReference, Pointer, int, int, int).

      • sodiumPad

        boolean sodiumPad​(com.sun.jna.ptr.IntByReference paddedBuffLen,
                  com.sun.jna.Pointer buf,
                  int unpaddedBufLen,
                  int blockSize,
                  int maxBufLen)
        Adds extra padding to a buffer buf whose original size is unpaddedBufLen in order to extend its total length to a multiple of blocksize.
        Parameters:
        paddedBuffLen - New length of buffer.
        buf - The buffer byte array.
        unpaddedBufLen - The length of buf with no padding.
        blockSize - Block size.
        maxBufLen - The absolute maximum you want this buffer length to be.
        Returns:
        False if the padded buffer length would exceed maxBufLen.

      • sodiumUnpad

        boolean sodiumUnpad​(com.sun.jna.ptr.IntByReference unpaddedBufLen,
                    com.sun.jna.Pointer buf,
                    int paddedBufLen,
                    int blockSize)
        Computes the original, unpadded length of a message previously padded using sodiumPad(IntByReference, Pointer, int, int, int). The original length is put into unpaddedBufLen.
        Parameters:
        unpaddedBufLen - This will be populated with the unpadded buffer length.
        buf - The buffer.
        paddedBufLen - The padded buffer size.
        blockSize - The block size.
        Returns:
        True if the buffer was unpadded.
