Important Host Certificates Update Information
PSC's current host certs will be replaced shortly as they expire on March 5, 2014. This annual procedure is normally a transparent transition, but as required by IGTF, we will begin signing our new host certificates using sha256.
Testing with GSI-OpenSSH and Globus GridFTP has shown no problems so far with sha256-signed certificates, as long as the OpenSSL version used with these services is at least OpenSSL 0.9.8o [01 Jun 2010] - newer releases after OpenSSL 0.9.8o, including OpenSSL 1.x.x are OK too.
Old Globus 4.x-based web services, however, including the TeraGrid/XSEDE MDS information service, balk on sha2* signatures due to reliance on an old library, so we will issue a new (host) container certificate for PSC's TeraGrid/XSEDE MDS service signed using SHA1. All other PSC Host CA-issued certificates will be signed using SHA256.
Per IGTF guidelines (see http://www.eugridpma.org/documentation/hashrat/sha2-timeline), all existing SHA1-signed certificates must expire or be revoked no later than February 1, 2015.
Certificate revocation lists (CRLs) for PSC CAs will remain signed using SHA1 until September 30, 2014 or until our last outstanding SHA1-signed certificate has expired or is revoked, whichever occurs first. CRLs for PSC CAs will be signed using SHA256 thereafter.
Notice will be sent and posted at http://www.psc.edu/ca/ if changes to this schedule are made.

XSEDE serves as the Registration Authority for the PSC MyProxy CA. To obtain user certificates from the PSC MyProxy CA, you must use MyProxy client software together with your XSEDE username and password. For more information, please see the Getting Started Guide on the XSEDE website.
