Please use the CERN Grid Certification Authority
to get a new certificate for Grid usage.
The CERN Trusted Certification Authority is no longer the official CERN Certification Authority. The
CERN Grid Certification Authority should be
used instead to get a new Grid certificate.
The CERN Trusted Certification Authority will keep issuing certificates until 1 June 2014, but should be used
only by users that explicitly need a SHA-1 certificate for compatibility reasons with some Grid software that is
not yet compatible with SHA-2 certificates.
Please note that the validity of new certificates issued by this Certification authority is limited to
6 months (instead of one year).
