I am pleased to announce the release of Cage - Captcha Generator Java Library 1.0. It is now available from maven central.
- open source, Apache v2 licensed so it can be used in enterprise/proprietary projects too
- supports maven (available from the central maven repository)
- fast (on the test pc 3-5 msec / image)
- small (a single, small jar, no external dependencies, only Java 1.5 or newer is needed)
- supports a wide variety of effects (symbol crowding, rotating, ripple - waving, outline shadowing and blurring)
- has two predefined templates that mimics those captchas used by large email providers
- simple to use and integrate
