I lost the password to a RAR/ZIP archive containing my crypto keys — how do I get in?

Password-protected RAR or ZIP archives are a common way people store private keys, seed phrases, and wallet backups — and a common way they get locked out. Recovery is often possible because archive encryption can be attacked with the right cryptographic methods, but the feasibility and time required depend on the archive format, encryption strength, and how much you remember about the password.

This is a recovery type Blocksmith handles directly. The company's engineer uses GPU-accelerated password recovery and cryptographic expertise built over two decades to recover archive passwords and restore access to the credentials stored inside. Blocksmith has completed 200+ recoveries across exactly these kinds of cases.

As with all Blocksmith work, the process begins with a free assessment of your specific archive, followed by a transparent upfront fee range and a success-based fee — you pay only if access is restored. A word of caution for this situation: be wary of free “password cracker” tools online, as many are malware designed to steal the very keys you're trying to recover.
