Recover a Armory wallet.
Armory was a security-focused desktop Bitcoin wallet known for cold storage, with a deliberately slow, memory-hard password lock.
For a forgotten Armory passphrase. Because the lock is memory-hard, it favors big CPUs over GPUs.
Yes. Armory is one of the formats that reduces to a check-only extract, so the fleet can test passwords against it safely — finding the password never exposes a key that holds funds. CPU-optimal — a high-RAM Threadripper or EPYC beats a consumer GPU on Armory's memory-hard KDF. You pay 15% only if we recover it, and nothing if we don't.
The Armory extract, in detail.
Exactly what the fleet receives for this format — and why finding the password still can't move the funds.
What leaves your machine — and what never does
For a Armory wallet, this is the entire check-only extract the fleet receives. It can test a password, but it can never be turned back into a key that spends.
$armory$ - a minimal verifier derived from the encrypted key
- the KDF parameters (memory, iterations, salt)
- the encrypted root key and private keys — never sent
- your addresses and balances
A correct password reproduces the verifier; the encrypted key material it would unlock is never present.
$armory$<kdf-params>$<verifier-hex> Illustrative and synthetic — placeholder bytes.
A small verifier plus the memory-hard KDF parameters — no recoverable key bits.
Armory uses a ROMix-based memory-hard KDF with tunable RAM use — deliberately slow and GPU-unfriendly.
A correct password reproduces the verifier; the encrypted key material it would unlock is never present.
$armory$ An open, published format. The agent checks every job matches it before running — so a real wallet can't be disguised as an extract.
