Encryption Settings

By default, CrashPlan PRO encrypts your backup data with an encryption key before sending it to your destinations. Your security setting determines how the encryption key itself is secured. No matter what security setting you use, your data is encrypted.

Note: The default setting uses your EID and password.

Secure with Private Password

You can choose to use a private password, which is different from your account password, to secure your encryption key. If you do this, your encryption key will be protected with your private password and stored on the servers and in the archive. Securing your encryption key with another password offers another level of security and prevents the administrators of the CrashPlan service from being able to decrypt your data. However, you will be required to provide this password to recover any data from the archive.

To set a private password:

  1. Click the Settings page.
  2. Click the Security tab.
  3. In the Archive Encryption Key area, click Secure with private password.
  4. In the Private Password box, enter your private password.
  5. Retype the password, exactly as you typed it above.
  6. Click OK.
  7. On the Settings page, click Save.

Secure with Private Encryption Key

With this option, you replace the default encryption key with a private key that is then used to encrypt your archive. This private encryption key is never sent to the servers and is stored only on the source machine and never leaves the source, so it is not even secured there. This is in fact the most secure option, but it requires the most user management because you must provide your private key when doing any restore. You can create your private key in several ways:

  • Enter a passphrase that will return a private encryption key that you paste into the encryption key box
  • Allow CrashPlan PRO to generate a private encryption key for you without entering any text (just click the Generate option)
  • Import an encryption key that you had previously saved to a text file

Once you've selected the method for generating your private key, you can export the key to a text file. Exporting the private key to a file makes it easier to locate the key in case you forget it. When you need to supply the private key on another computer to which you want to recover files, you can use the Import option to import the encryption key from the text file.

Warning: Any previously backed up data associated with the old encryption key will be deleted. Your backups will begin again using the new private encryption key.

Option 1: Create a private key with a passphrase

  1. Click the Settings page.
  2. Click the Security tab.

  5. Enter the text for the passphrase.
  6. In the Repeat box, enter the passphrase again.
  7. Click OK. CrashPlan PRO generates a private key

  1. Click the Settings page.
  2. Click the Security tab.
  3. In the Archive Encryption Key area, click Replace with your own private key.
  4. Click the Generate option. CrashPlan PRO generates the text for your new private key.
