Display HASH Results



    When an input (file, typed-string) is processed with a HASH function, the rendered
    result can be displayed in several format.
    The most communly used is the Hexadecimal representation or Base16.
    96Crypt provides 3 different display format that can be changed on-the-fly.



    • 1. Base16
          Base16 (Hexadecimal) is the most used format to display HASH function results.
          As each 4 binary bits (nibble) are represented in 1 hexadecimal digit,
            0[decimal] -> 0000[binary] -> 0[hex]   up to
          15[decimal] -> 1111[binary] -> F[hex]
          the Base16 result will be much shorter (1/4) than the binary format.

          Once the HASH results are rendered and displayed on your screen, you might
          simply click on the "Display Mode" box placed on the upper right corner and select
          "Digest Base16".

    • 2. Base64
          Base64 is a method of encoding arbitrary binary data as ASCII text.
          This is necessary for sending files via Internet email, which can only
          handle 6-bit ASCII text.
          Since Base64 encoding divides every group of 3-byte (3 x 8 = 24bit) of the original
          data into 4 x 6-bit ASCII text (4 x 6 = 24bit), the encoded result is typically about one
          thrid bigger. 6-bit ASCII text represents a max of 64 bits hence the name Base64.

          Here's an example of encoding in Base64.
          Let us consider the following sequennce BCD and encode it in Base64.
          The ASCII character B is equal to 66[decimal] or 0100 0010[binary]
          The ASCII character C is equal to 67[decimal] or 0100 0011[binary]
          The ASCII character D is equal to 68[decimal] or 0100 0100[binary]
          The resultant bit-stream of the 3 bytes is 0100 0010    0100 0011    0100 0100
          This can be represented as   4 x 6-bit  -->   010000   10 0100   0011 01  000100
          Let's convert each block of 6-bit to decimal    16            36            13            4
          From the Base64 encoding table shown below we replace every decimal value
          by its ASCII code and we get the final result QkNE
          Therefore the sequence BCD is encoded to QkNE in Base64 (it is one third bigger).

      Value Char   Value Char   Value Char   Value Char
      0 A   16 Q   32 g   48 w
      1 B   17 R   33 h   49 x
      2 C   18 S   34 i   50 y
      3 D   19 T   35 j   51 z
      4 E   20 U   36 k   52 0
      5 F   21 V   37 l   53 1
      6 G   22 W   38 m   54 2
      7 H   23 X   39 n   55 3
      8 I   24 Y   40 o   56 4
      9 J   25 Z   41 p   57 5
      10 K   26 a   42 q   58 6
      11 L   27 b   43 r   59 7
      12 M   28 c   44 s   60 8
      13 N   29 d   45 t   61 9
      14 O   30 e   46 u   62 +
      15 P   31 f   47 v   63 /

          If the size of the original data in bytes is a multiple of three, everything works fine.
          But what if it isn't? like BCDE.
          As the Base64 encoding processes a group of 3-byte (3 x 8bit) at a time, the
          solution is to append enough bytes with a value of '0' to complete to 3-byte group.
          These trailing '0's are NOT encoded using the Base64 encoding table. They are rather
          padded as a "=" character appearing at the end of encoded data.


          To convert the HASH result to Base64 using 96Crypt, all you need is a simple click on
          the "Display Mode" box placed on the upper right corner and select "Digest Base64".

    Note:
    The Base64 format provided by 96Crypt is derived from the ASCII not from the Hexadecimal representation.




    • 3. ASCII
          American Standard Code for Information Interchange (ASCII) is the numerical
          representation of a characters. The first 32 codes are non-printing characters, this
          makes this choice a bit harder to manipulate. However, if printing the results
          cannot always be successful, saving them to a file can be easily done.

          Once the results are rendered and displayed on your screen, you might simply
          click on the "Display Mode" box placed on the upper right corner and select
          "Digest ASCII".

    Note:
    When opening 96Crypt, it will auto-position on the last display mode selection that
    was saved the last time 96Crypt was closed.
