    PassageWay uses AES-CBC 256-bit encryption for your Vault data, and PBKDF2 SHA-256 to derive your encryption key.

    PassageWay always encrypts and/or hashes your data on your local device before anything is sent to cloud servers for storage. PassageWay servers are only used for storing encrypted data. For more information, see Storage.

    Vault data can only be decrypted using the key derived from your master password. PassageWay is a zero knowledge solution, meaning you are the only party with access to your key and the ability to decrypt your Vault data.

    Tip

    We encourage you to visit our Interactive Cryptography Page to see for yourself how PassageWay encrypts your data.

    If you’d like to learn more about how these encryption keys are used to protect your Vault, you can also check out our Security Whitepaper.

    AES-CBC

    AES-CBC (Cipher Block Chaining), used to encrypt Vault data, is a standard in cryptography and used by the US government and other government agencies around the world for protecting top-secret data. With proper implementation and a strong encryption key (your master password), AES is considered unbreakable.

    PBKDF2

    PBKDF2 SHA-256 is used to derive the encryption key from your master password. PassageWay salts and hashes your master password with your email address locally, before transmission to our servers. Once a PassageWay server receives the hashed password, it is salted again with a cryptographically secure random value, hashed again, and stored in our database.

    The default iteration count used with PBKDF2 is 100,001 iterations on the client (client-side iteration count is configurable from your account settings), and then an additional 100,000 iterations when stored on our servers (for a total of 200,001 iterations by default). The Organization key is shared via RSA-2048.

    The utilized hash functions are one-way hashes, meaning they cannot be reverse engineered by anyone at PassageWay to reveal your master password. Even if PassageWay were to be hacked, there would be no method by which your master password could be obtained.

    Invoked Crypto Libraries

    PassageWay does not write any cryptographic code. PassageWay only invokes crypto from popular and reputable crypto libraries that are written and maintained by cryptography experts. The following crypto libraries are used:
