How it Works?

Passky uses a combination of advanced encryption methods to ensure the security of your data.

Passky is based on a zero trust architecture and uses advanced encryption methods such as XChaCha20 and Argon2id to ensure the security of your sensitive data.

For sensitive data encryption, Passky uses XChaCha20, a state-of-the-art encryption algorithm that provides a high level of security and performance. This encryption method is designed to be resistant to known-plaintext attacks and other forms of cryptanalysis.

For master password hashing, Passky uses Argon2id, a password-hashing algorithm that has been recognized as the winner of multiple password-hashing competitions, such as the Password Hashing Competition (PHC) held by the community. It is designed to be resistant to brute-force attacks. This algorithm uses a combination of memory-hard and data-dependent techniques to make it difficult for attackers to guess your master password.

When you save your account information to Passky, all sensitive data is fully encrypted using XChaCha20. The encrypted data is then stored on Passky's servers.

When you try to access your account, Passky will prompt you to input your master password. The master password is then hashed using Argon2id algorithm to ensure its security. The hashed master password is then used to decrypt the sensitive data, allowing you to access your account.

In summary, Passky uses advanced encryption methods such as XChaCha20 and Argon2id to ensure the security of your sensitive data and master password, making it difficult for anyone to access your information without your permission.

Development

bun install
bun run test
bun run typecheck
bun run dev

bun run dev starts the server with file watching. Settings are read from .env. The tests never load it and always run against an in-memory SQLite database.

Pull requests to main run the type check and test suite. Pushes to main publish rabbitcompany/passky-server:latest, and GitHub releases publish the versioned image tags.
