Recover a mSIGNA wallet.
mSIGNA is a multi-signature-capable Bitcoin wallet with password-encrypted keys.
For a forgotten mSIGNA password on an existing wallet.
Yes. mSIGNA 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. GPU-friendly. You pay 15% only if we recover it, and nothing if we don't.
The mSIGNA 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 mSIGNA 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.
$msigna$ - the last half of the encrypted private key
- 16 bytes of encrypted padding
- the first half of the private key — never sent
- your addresses and balances
Predictable padding confirms a correct password; the half-key fragment cannot be turned into a spendable key.
predictable padding $msigna$<half-privkey-hex>$<padding-hex> Illustrative and synthetic — placeholder bytes.
Half an encrypted private key plus 16 bytes of padding.
mSIGNA derives its key from the password and a salt, then AES-encrypts the key material.
Predictable padding confirms a correct password; the half-key fragment cannot be turned into a spendable key.
$msigna$ An open, published format. The agent checks every job matches it before running — so a real wallet can't be disguised as an extract.
