The .bb2 format is a proprietary, encrypted container. It utilizes robust cryptographic algorithms to secure the backup data, typically including a password or a seed phrase for decryption. The internal structure is designed to ensure data integrity and can include metadata alongside the wallet data itself. It is not designed to be human-readable or directly editable without the BitBox Backup 2 software and the correct credentials.

Security Information

.bb2 files contain highly sensitive financial data. Always store them on secure, offline media if possible, and protect the associated password or seed phrase with extreme care. Never share your password or seed phrase, and be wary of any software claiming to decrypt .bb2 files without official credentials.
