SQRLL_Encryption is a cryptographic framework designed for symmetric encryption and decryption.

It's my learning project.

General info

• Project is written in C++ with a little bit of CMake

Pros

• It's very fast
• uses random IV - outputs are "random" you should not get same output twice
• Should be safe (I'm not cryptography analyst to guarantee)

Cons

• Never tested in production
• Takes too much space for production use (Could be tweaked using settings but it would be speed <==> safety choice)

What does this encryption support?

• XORCascade
• BitRotation
• BitFlipping
• Shuffle
• And a little bit more

Tests output

This is summary, for whole output go to Tests dir (there is another readme) or run yourself (use clion for one-click compile)

1. CORRECTNESS TEST

   • ✅ PASS - All decryptions correct

2. AVALANCHE EFFECT TEST

   • Bit change: 47.9%
   • ✅ PASS - Good diffusion

3. ENTROPY TEST

   • Entropy: 7.00 bits/byte
   • ✅ PASS - Good randomness

4. PATTERN DETECTION TEST

   • Unique outputs: 5/5
   • ✅ PASS - No repeating patterns

5. PERFORMANCE TEST

   • 1000 encrypt/decrypt: 190ms
   • ✅ FAST
