🛡️ How MyColdKey Works
Encrypt — Password-hardened encryption using modern cryptography (Argon2id + AES-256-GCM + HMAC).
Store — Keep encrypted copies across locations without increasing plaintext exposure.
Recover — Restore using your encrypted backup + password (in-app or Self-Contained Recovery Kit).
Your hardware wallet secures spending. MyColdKey secures recovery.
Bonus: Generate fresh BTC/ETH wallets and store them like any other secret.
QR / File / Text / SSS
Discovery doesn't reveal your secret.
Self-Contained Recovery Kit (exported from the app)
Same encrypted backup, any method — offline, with your password only.
Recovery stays offline and vendor-independent.
Recommended: verify downloads (checksums.txt) and test recovery with non-critical data first.
