| 6 | File based digest authentication helper for Squid. | |

| 10 | .SH SYNOPSIS | |
| 11 | .if !'po4a'hide' .B digest_file_auth | |

| 15 | .SH DESCRIPTION | |
| 16 | .B digest_file_auth | |
| 17 | is an installed binary authentication program for Squid. It handles digest | |
| 18 | authentication protocol and authenticates against a text file backend. | |
| 19 | . | |
| 20 | .SH OPTIONS | |
| 21 | .if !'po4a'hide' .TP 12 | |
| 22 | .if !'po4a'hide' .B \-c | |
| 23 | Accept digest hashed passwords rather than plaintext in the password file | |
| 24 | . | |
| 25 | .SH CONFIGURATION | |
| 26 | .PP | |
| 27 | Username database file format: | |
| 28 | .TP 6 | |
| 29 | - comment lines are possible and should start with a '#'; | |
| 30 | . | |
| 31 | .TP | |
| 32 | - empty or blank lines are possible; | |
| 33 | . | |
| 34 | .TP | |
| 35 | - plaintext entry format is username:password | |
| 36 | . | |
| 37 | .TP | |
| 38 | - HA1 entry format is username:realm:HA1 | |
| 39 | . | |
| 40 | .PP | |
| 41 | To build a directory integrated backend, you need to be able to | |
| 42 | calculate the HA1 returned to squid. To avoid storing a plaintext | |
| 43 | password you can calculate | |
| 44 | .B MD5(username:realm:password) | |
| 45 | when the user changes their password, and store the tuple | |
| 46 | .B username:realm:HA1. | |
| 47 | then find the matching | |
| 48 | .B username:realm | |
| 49 | when squid asks for the HA1. | |
| 50 | .PP | |
| 51 | This implementation could be improved by using such a triple for | |
| 52 | the file format. However storing such a triple does little to | |
| 53 | improve security: If compromised the | |
| 54 | .B username:realm:HA1 | |
| 55 | combination is "plaintext equivalent" - for the purposes of digest authentication | |
| 56 | they allow the user access. Password syncronisation is not tackled | |
| 57 | by digest - just preventing on the wire compromise. | |
