Digest authentication

HTTP Digest authentication is an improvement over the regular unencrypted HTTP Basic authentication mechanism, allowing user identity to be established securely without having to send a password over the network. HTTP Digest authentication is an application of MD5 cryptographic hashing with the use of the nonce value (for more information on the nonce value, refer to http://en.wikipedia.org/wiki/Cryptographic_nonce) to prevent cryptanalysis.

The following auth_param parameters are available for configuring HTTP Digest authentication helpers:

auth_param digest program COMMAND
auth_param digest utf8 on|off
auth_param digest children NUMBER [startup=N] [idle=N] [concurrency=N]
auth_param digest realm STRING
auth_param digest nonce_garbage_interval TIME
auth_param digest nonce_max_duration TIME
auth_param digest nonce_max_count NUMBER
auth_param digest nonce_strictness on|off
auth_param digest check_nonce_count on|off
auth_param digest post_workaround on|off
