Which encryption algorithm is used by Blackberry devices for Password Keeper?

• A. 3DES
• B. AES
• C. Blowfish
• D. RC5

Answer: (B)

Protecting data at rest in a password vault relies on a strong symmetric cipher. BlackBerry’s Password Keeper uses AES to encrypt the vault’s contents, meaning every stored password and note is unreadable without the master password-derived key. AES is favored because it provides robust security with keys of 128, 192, or 256 bits and is efficient on modern devices, making it the standard choice for protecting sensitive data in apps and operating systems. Older ciphers like 3DES, Blowfish, and RC5 exist, but they have known drawbacks or less optimal performance today. 3DES, for instance, uses shorter block sizes and is slower and less future-proof than AES. Blowfish and RC5 are older designs that have largely been supplanted by AES in contemporary password managers. So AES offers the best balance of strong security and practical performance for protecting a user’s Password Keeper data.
