More on 1Password’s Components

Stefan van As of 1Password fame sent me a more exhaustive list of the libraries and tools used in 1Password. I thought I would share it with everyone. He also recently started blogging about security, software development and Delphi.

Here is an overview of the 3rd party components used in 1Password:

• 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

Also uses the following tools:

• EurekaLog -- For diagnostics reporting
• FinalBuilder -- For build management
• Inno Setup -- The installation wizard

A lot of great tools and libraries there.
