International Grid Trust Federation (IGTF) Distribution of Authority Root Certificates.
The distribution contains root certificates and related meta-information: Certificate Revocation List (CRL) locations, contact information, and signing policies. This distribution is subject to the IGTF Federation Document and the appropriate charters and authentication profiles. Please refer to your local PMA ( EUGridPMA, APGridPMA or TAGPMA ) for more information.
The IGTF itself does not provide identity assertions but instead asserts that - within the scope of its charter - the certificates issued by the Accredited Authorities meet or exceed the relevant guidelines.
The orignal collection of CA packages was formerly distributed under the name "EUGridPMA".
