- Browser Helper Objects (BHOs) -- this is what powers 1Password inside Internet Explorer.
- Bonjour -- this is what powers Wi-Fi Sync. (here is an unrelated Delphi implementation)
- ChilkatCrypt -- this is what powers some of our crypto
- MS Crypto -- this is the Pseudo Random Number Generator (PRNG)
- DISQLite -- Some of 1Password's features - such as Watchtower, for example - are utilizing SQLite. Because 1Password 4 is in Delphi 2007, we use DISQLite for that (today, it would be using FireDAC for that)
- dxgettext -- this is used to localize 1Password. It works nicely with Crowdin, a localization project management platform
- GraphicEx and Graphics32 -- this gives (alpha channel) transparency
- HyperString -- super fast string handling routines. (no longer available)
- OpenSSL -- this is what powers PBKDF2 (among other crypto routines)
- sgcWebSockets -- The WebSockets are used with the Chrome and Firefox browser extensions
- StreamSec -- another crypto library, mostly for SSL/TLS
- zlib and LibTar -- For OS X-compatible compression routines
I also found an implementation of the Time based One Time Password in Delphi that is compatible with Google Authenticator. While it wasn't used in 1Password, it should provide some similar functionality.
For more information on the cryptography used in 1Password, you can check out their security whitepaper.
Stefan goes by the handle of Dutch Delphi Dude, and 1Password is not his first cool app. He's done Delphi development for other popular apps:
- Macromedia Authorware
- Macromedia Dreamweaver
- Adobe Captivate
