NAME

raptcha

SYNOPSIS

low drain bamage, storage-less, session-less, plugin-less, zero
admin,
single-source-file secure captcha system for ruby and/or rails

DESCRIPTION

raptcha manages image generation via a streaming controller. the
result is
that no disk storage is ever needed for captcha images. it also
manages
authentication via blowfish encoded hidden fields, obviating the
need for
session/database interaction for captcha validation. the library
is useful
outside of rails, even from the command line.
