Effective immediately, this new key is available and will be valid until Monday, November 1, 2004. To obtain further information or to download the new CERT/CC public PGP key, please visit
The passphrase used to protect the previous CERT/CC PGP key was accidentally exposed to a small number of non-CERT/CC personnel with whom we have a close working relationship.

The revocation certificate for PGP key id 0x3D2BFD15 has also been included here and sent to the public PGP key servers.
