All editions of XColdPro share the same cryptographic core. These are not optional add-ons — they are the base layer of every wallet operation.
| Layer | Technology | Protection |
|---|---|---|
| Encryption | AES-256 | NIST FIPS 197 standard. 10^68 years to brute-force at 1 billion attempts/sec |
| Key Derivation | PBKDF2 (100K iterations; up to 500K with Nyxor) | ~500ms per password attempt. Rainbow table immune (random 128-bit salt per wallet) |
| Integrity | SHA-256 Checksums | Detects even single-bit file modifications. Prevents tampered backup execution |
| Signing | Deterministic ECDSA (RFC 6979) | Eliminates catastrophic nonce reuse vulnerability. Automatic protection |
| Memory | Release on exit | References to decrypted key material are dropped and the process is terminated. Memory returns to the operating system on exit |
