About This Audit Chain
🔒 Hash Algorithm
SHA-256
Web Crypto API (browser built-in). No external library. Each block hashes its content + previous block hash.
⚙ Kernel Signature
HMAC-SHA-256
Each SLDA result is signed with the algorithm ID key. Proves the exact kernel version produced the classification.
