Bitwise Cryptographic Vault & Integrity Engine

A C utility applying bitwise XOR key rotation for symmetric payload transformation alongside byte-level checksum hashing for data integrity verification.

Features

• XOR Cipher Transformation: Encrypts and decrypts text streams using bitwise XOR logic gates.
• Integrity Hash Check: Computes dynamic byte checksums to detect file tampering or corruption.
• Low Memory Footprint: Zero external dependencies, built entirely using core C primitives.

Compilation & Run

gcc vault.c -o vault
./vault
