fetch-crl - the Certificate Revocation List retrieval tool |

============================================================================== |

|

|
|
The fetch-crl utility will retrieve certificate revocation lists (CRLs) for |
6 |
|
|
a set of installed trust anchors, based on crl_url files or IGTF-style info |
7 |
|
|
files. It will install these for use with OpenSSL, NSS or third-party tools. |

CONFIGURATION |
53 |
|
|
------------- |
54 |
|
|
The fetch-crl3 tool has built-in defaults that are suitable for 'grid' setups, |
55 |
|
|
where trust anchors are installed in /etc/grid-security/certificates. It will |
56 |
|
|
usually do what you want, if you use OpenSSL-like applications. |
57 |
|
|
|
58 |
|
|
If you want, you can tune fetch-crl in a myriad of ways, by setting any of the |
59 |
|
|
flags or options in the configuration file. This configuration file is looked |
60 |
davidg |
1878 |
for in "/etc/fetch-crl.conf" by default, but an alternative location can be |
61 |
davidg |
1758 |
specified with the "-c" command-line option. |
62 |
|
|
|
63 |
|
|
Please look at the web site or in the example configuration file for more |
64 |
|
|
explanation of the various configuration settings. |

CONTRIBUTIONS AND ACKNOWLEDGEMENTS |
69 |
|
|
---------------------------------- |
70 |
|
|
Fetch-crl3 is a complete re-write of the utility, but of course owes to the |
71 |
|
|
extensive experience and contributions made over time by the contributors to |
72 |
|
|
fetch-crl 1.x and 2.x, and to the people that reported bugs and feature |
73 |
|
|
requests. |
74 |
|
|
The original fetch-crl was developed for the acclaimed EU DataGrid project by |
75 |
|
|
Fabio Hernandez and many significant contributions were made by Steve Traylen. |
76 |
|
|
|
77 |
|
|
Fetch-crl3 was developed by David Groep, mainly for enjoyment, with the help |
78 |
|
|
of large quantities of coffee and Spa Rood, and minimal quantities of sleep. |
