How to compress an integer to a smaller string of text?

Asked 2021-Jun-01 at 21:47

Given a random integer, for example, 19357982357627685397198. How can I compress these numbers into a string of text that has fewer characters?

The string of text must only contain numbers or alphabetical characters, both uppercase and lowercase.

I've tried Base64 and Huffman-coding that claim to compress, but none of them makes the string shorter when writing on a keyboard.

I also tried to make some kind of algorithm that tries to divide the integer by the numbers "2,3,...,10" and check if the last number in the result is the number it was divided by (looks for 0 in case of division by 10). So, when decrypting, you would just multiply the number by the last number in the integer. But that does not work because in some cases you can't divide by anything and the number would stay the same, and when it would be decrypted, it would just multiply it into a larger number than you started with.

I also tried to divide the integer into blocks of 2 numbers starting from left and giving a letter to them (a=1, b=2, o=15), and when it would get to z it would just roll back to a. This did not work because when it was decrypted, it would not know how many times the number rolled over z and therefore be a much smaller number than in the start.

I also tried some other common encryption strategies. For example Base32, Ascii85, Bifid Cipher, Baudot Code, and some others I can not remember.

It seems like an unsolvable problem. But because it starts with an integer, each number can contain 10 different combinations. While in the alphabet, letters can contain 26 different combinations. This makes it so that you can store more data in 5 alphabetical letters, than in a 5 digit integer. So it is possible to store more data in a string of characters than in an integer in mathematical means, but I just can't find anyone who has ever done it.

QUESTION

Python base32 decode result is different

Asked 2021-May-15 at 06:20

This question may sound stupid, but it had troubled me for days.

Basically, I used base64_b32decode() to decode a base32 (RFC 3548 / RFC4648) key in python.

The result is b'\x07\xe7\xabN\xe9\x15k\xb9\x1eC\x0eR\x1a\xd3\xcd\xb09` F'

However, when I used this website to decode the key.

The website's result is 07 e7 ab 4e e9 15 6b b9 1e 43 0e 52 1a d3 cd b0 39 60 20 46.

The problem is I don't know why does python returned 'abN' when the website showed 'ab'. Mind the additional N in the string.

I mean ... why does python returned extra characters and also it seems to me that there are still b0 39 60 20 46 byte missing.

Am I doing something wrong?

Those strings are identical. The value of the ASCII character N is 0x4E, and the last for (0x39 0x60 0x20 0x46) are "9" "space" "space" "F". When Python prints a byte string, it prints all normal characters as normal characters, and the non-printable characters show up as hex escapes. Use

PHP Convert Hext To Base32 And Vice Versa

Asked 2021-Apr-23 at 22:54

I am facing problem to convert a hex representation to base 32 and vice versa.

all online convert is JavaScript based, but i can't find any PHP based solution after quite search here and there :(

i have tried base32Encode the hex value, hexdec then base32 encode none of them work actually :(

hex: 686aa8fca1767a5c1cc23b0f982380d6ba6d07ff32fafe8e

base32: NBVKR7FBOZ5FYHGCHMHZQI4A225G2B77GL5P5DQ

what i need here, i need to get (convert) the base32 value from the hex value and vice versa like get the hex value from the base 32.

that's all

Update 1:

following site can encode from hex to base32 in a way what exactly i am looking for but. but i don't know how they do it.. :(

You can see that base32 is using A-Z and 2-7 as encoding. Zeros will not change anything.

To emulate casting to byte (byte)variable just try to do variable & 255 in JS. That way you leave lower 8 bits of a number just like casting to byte does in C#.

P.S. And I suppose you don't need to use Uint8Array

Install base32

You can download it from GitHub.
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
