Manual Reference Pages - BASIC_NCSA_AUTH (8)
basic_ncsa_auth - NCSA httpd-style password file authentication helper for Squid
basic_ncsa_auth allows Squid to read and authenticate user and password information from an NCSA/Apache
httpd-style password file when using basic HTTP authentication.
This password file can be manipulated using
This authenticator accepts:
* Blowfish - for passwords 72 characters or less in length
* SHA256 - with salting and magic strings
* SHA512 - with salting and magic strings
* MD5 - with optional salt and magic strings
* DES - for passwords 8 characters or less in length
NOTE: Blowfish and SHA algorithms require system-specific support.
The only parameter is the password file.
It must have permissions to be read by the user that Squid is running as.
basic_ncsa_auth must have access to the password file to be executed.
DES functionality (used by htpasswd by default) silently truncates passwords to 8 characters.
Allowing login with password values shorter than the one desired.
This authenticator will reject login with long passwords when using DES.
