Exporting from Keychain

...

Warning

When you export/download a digital certificate, you will receive both public and private keys. The public keys are the ones that you will use to sign and encrypt emails. The private keys are the ones that will be stored on your computer. You should never share the private key(s).

WARNING: If someone else has access to your private keys, they can impersonate you or read your encrypted emails.

Creating a backup copy

Your personal digital certificate will be stored in Stache.  You can however elect to store it elsewhere. There are several options:

  • Burn the contents to a CDROM

  • Copy the files to portable media such as a Flash drive

  • Copy the files to UTBox, which is approved for the storage of sensitive information.

Warning

Regardless of which medium you wish to store your certificate and private key, remember to secure the medium. 

Do not ask anyone else (such as desktop staff) to store or keep copies of your certificates.  This is a security risk and not approved by ISO.

If you are creating a backup copy

There are several options for storing your backup copy of your certificates. You can:

  • Use portable media, such as a flash drive. Save the files to the drive and then store the flash drive in a secure location, such as a locked file cabinet or a safe.

  • Use a CD. Write the files to the CD and then store the CD in a secure location, such as a locked file cabinet or a safe.

Remember that you MUST have the password you created in step 7, above, in order to use the backups.

Please do not ask anyone else, such as desktop support staff, to store the backup copies of your certificates for you. It is a security risk to allow someone else to have access to the private keys that are included in the backup files.

If you are moving the files to another device or computer

There are several options for moving your certificate files from one machine to another. You can:

  • Use portable media, such as a flash drive. Save the files to the drive in the first computer and then move the flash drive to the other computer.
