entropy — Air-gapped 256-bit entropy generator for BIP39 cold wallets. Pure AT&T assembly, builds for Windows (MinGW-w64). Seven independent layers of hardware entropy: RDRAND quantum noise, RDTSC system chaos, cache-miss jitter, pipeline bomb, golden ratio mixer, cross-linked ARX avalanche, and ROL+ADD+XOR anti-backdoor merge. Compromise any one layer — the other six preserve unpredictability. Pipe the output directly into iancoleman/bip39 for mnemonic generation.
Your crypto keys depend on OpenSSL — 500,000 lines of C. Heartbleed. The Debian bug. Dual_EC_DRBG. The entire attack surface, replaced by 500 lines of auditable assembly. Not a CSPRNG. Not a key generator. A raw entropy seed. You bring the hash function.
# Generate entropy
./entropy.exe > seed.hex
# Paste into BIP39 (offline version of iancoleman/bip39)
# Open bip39-standalone.html in a browser
# Paste the contents of seed.hex into the "Entropy" field
# Receive 24 mnemonic wordsBinaries are signed with the author's signature. No libraries, no backdoors, pure assembler.
