How JexCrypt Works
function JexCrypt(plaintext, key, rounds = 5):
1. SALT GENERATION
└─ Generate 16-byte random salt
└─ Combine: saltedKey = salt + key
2. KEY DERIVATION
└─ Derive keyBytes using S-Box transformation
└─ Length: plaintext.length + 64 bytes
3. ENCRYPTION ROUNDS (repeat N times)
├─ a) SUBSTITUTION
│ └─ Apply S-Box to each byte (AES-like)
├─ b) XOR OPERATION
│ └─ XOR data with key-derived bytes
├─ c) BLOCK TRANSPOSITION
│ └─ Swap positions in 4-byte blocks
└─ d) BIT ROTATION
└─ Rotate bits by (round + 1)
4. OUTPUT
└─ Encode to Base64
└─ Format: JXC:{rounds}:{salt64}:{cipher64}
SECURITY FEATURES:
✓ Salt prevents rainbow table attacks
✓ Multiple rounds resist cryptanalysis
✓ S-Box provides non-linearity
✓ Key stretching via derivation functionCreated by Jexen
