nullsec-cryptwrap is a formally verified cryptographic wrapper written in Ada/SPARK. Leverages Ada's strong typing and SPARK's formal verification for provably correct cryptographic operations.

• 🔐 Verified Crypto - SPARK-verified AES, ChaCha20, RSA
• 📝 Secure Memory - Guaranteed memory zeroing
• 🛡️ Type Safety - Strong typing prevents crypto misuse
• ⏱️ Constant Time - Timing-attack resistant operations
• 📋 Auditable - Human-readable verification proofs
• 🔑 Key Management - Secure key generation and storage

• GNAT 2023+
• SPARK 2014 (for verification)

git clone https://github.com/bad-antics/nullsec-cryptwrap.git
cd nullsec-cryptwrap
gprbuild -P cryptwrap.gpr

# Encrypt file
./cryptwrap encrypt -i secret.txt -o secret.enc -k keyfile.key

# Decrypt file
./cryptwrap decrypt -i secret.enc -o decrypted.txt -k keyfile.key

# Generate key
./cryptwrap keygen -a aes256 -o key.key

# Hash file
./cryptwrap hash -i file.txt -a sha256

# Verify signatures
./cryptwrap verify -i file.txt -s file.sig -k public.key

SPARK verification proves:

• No buffer overflows
• No integer overflows
• No uninitialized memory access
• Correct key material handling
• Constant-time comparisons
• Memory properly zeroed after use
