Penetration test and code review of the 1Password system

Data is encrypted with AES-GCM-256. The vault key is derived from your account password using PBKDF2-HMAC-SHA256 at 650,000 iterations, then combined with a 128-bit Secret Key that never leaves your devices — so an attacker who guesses the password alone still cannot decrypt anything. Authentication uses SRP, so password-equivalent data is never sent to the server.

The vault is encrypted client-side with AES-256 in CBC mode. The key is derived from the master password with PBKDF2-SHA256 at a default 600,000 iterations for new accounts (older accounts kept far lower counts for years); one extra PBKDF2 round produces the login hash, and further rounds are applied server-side. Passwords, usernames and notes are encrypted, but item URLs and account metadata are stored unencrypted.
