This manual covers Roxen Challenger versions 1.3. It uses Pike 0.6 and is available for several different Unix flavors as well as Windows. The slight differences between the Unix and Windows versions are documented in the Portability chapter.

Roxen Challenger 1.3 is available with support for encryption with the HTTP protocol. Because of export control restrictions of cryptography Challenger is available with support for weak, 40-bit, encryption and with support for strong, 128/168-bit, encryption. Apart from the encryption support the different versions are identical. You can find out which version you have by reading the first page of the configuration interface.
