cthulhucrypt

CthulhuCrypt

A Python package featuring multi-layered, non-linear encryption combining:

• Bitwise XOR with golden ratio constants
• Dynamic substitution tables
• Chaotic math (primes, Collatz conjecture, trig functions)
• Recursive encryption pipelines

Features

Brute-force resistant: 10+ transformation layers

Position-dependent ops: Identical chars → different outputs

Zero dependencies: Pure Python (math only)

CLI support: Encrypt/hash text or files from terminal

Quick Start

pip install cthulhucrypt

from cthulhucrypt import ultra_encrypt

encrypted = ultra_encrypt("hello", iterations=7)
print(encrypted)  # Output: Ý°FtÔÖr&¥[8ª...

CLI Usage

See all commands

cthulhucrypt --help

Encrypt or hash a string

cthulhucrypt encrypt "hello world"
cthulhucrypt medhash "hello world"
cthulhucrypt highhash "hello world" --iterations 10
cthulhucrypt hash2 "hello world" --iterations 10
cthulhucrypt hash2-high "hello world" --iterations 10

Encrypt or hash a file

cthulhucrypt encrypt --file input.txt --output encrypted.txt
cthulhucrypt medhash --file input.txt --output hash.txt
cthulhucrypt highhash --file input.txt --iterations 10 --output hash.txt
cthulhucrypt hash2 --file input.txt --iterations 10 --output hash.txt
cthulhucrypt hash2-high --file input.txt --iterations 10 --output hash.txt

Decrypt a file or string

# If you have the output in the form ENCRYPTED;TABLE_IDX
cthulhucrypt decrypt "a1b2c3d4;5" --output decrypted.txt
# Or, if you have the encrypted text and table index separately
cthulhucrypt decrypt "a1b2c3d4" 5 --output decrypted.txt
# Or, from a file
cthulhucrypt decrypt --file encrypted.txt 5 --output decrypted.txt

Algorithm Breakdown

Character Pairing:

('h','e') → 104*101 = 10504 → [1,0,5,0,4]

Dynamic Substitution:

9 rotating substitution tables selected via sqrt(ascii_sum)*π + log(len)

Bitwise Chaos:

((char ^ position ^ 1618) << (i%3)) & 0xFF

Math Destruction:

Collatz conjecture + prime-modulated trig functions

Warning

Not for passwords: No salting/key stretching
