Hex data compression

  • How do I compress a hex file?

    If the data has a predictable pattern then it's compressible.
    You could (should) compress the data first (using any suitable compression algorithm, not necessarily an algorithm that's hex-specific), and then (if you need hex-encoding) hex-encode the compressed data.Oct 7, 2016.

  • How does hex encoding work?

    Hex encoding is a transfer encoding in which each byte is converted to the 2-digit base-16 encoding of that byte (preserving leading zeroes), which is then usually encoded in ASCII.
    It is inefficient, but it is a simple, commonly-used way to represent binary data in plain text..

  • What is a hex encoding?

    Encodes the input using hexadecimal (also 'hex' or 'base16') encoding.
    The result is comprised of 16 different symbols: The numbers '0' to '9' as well as the letters 'A' to 'F' (or 'a' to 'f', see below)..

  • What is Data Compression? Data compression is the process of encoding, restructuring or otherwise modifying data in order to reduce its size.
    Fundamentally, it involves re-encoding information using fewer bits than the original representation.
Oct 7, 2016I'm working on a project that requires a TCP connection between a client and server. The current protocol encodes the data into hex and then 

Can 32 hex numbers be compressed into 30 hex numbers?

If your question is to compress 32 hex numbers into 30 hex numbers.
This is impossible to occur for all test cases, since, if it were possible, multiple 32-length hex strings would have to compress to the same 30-length hex string, thus you wouldn't know which one it was ( the pigeonhole principle ).

Does Hex increase the length of a payload?

However, hex increases the length of the payload which isn't really optimal from a networking point of view.
Hex follows a pretty predictable pattern with repeating characters etc.
I was looking for a fast and preferably simple compression algorithm that works very well with Hex encoded strings.

History and Development

The motivation for creating the PNG format was the realization that, on 28 December 1994, the Lempel–Ziv–Welch (LZW) data compression algorithm used in the Graphics Interchange Format (GIF) format was patented by Unisys.
The patent required that all software supporting GIF pay royalties, leading to a flurry of criticism from Usenet users.

BinHex, originally short for binary-to-hexadecimal, is a binary-to-text encoding system that was used on the classic Mac OS for sending binary files through e-mail.
Originally a hexadecimal encoding, subsequent versions of BinHex are more similar to uuencode, but combined both forks of the Mac file system together along with extended file information.
BinHexed files take up more space than the original files, but will not be corrupted by non-8-bit clean software.
