You can use a combination of alphabets, numbers, and special characters in your passphrase.
After enabling GDPR, you cannot leave this field blank. However, if GDPR is already enabled and a passphrase exists, you can leave this field blank to use the existing passphrase or enter a new passphrase.
Note:
After entering a new passphrase, the files that are already encrypted with the older passphrase cannot be decrypted using the new one. You must use the older passphrase to decrypt them.
Note:
When you upgrade from an earlier release that had GDPR enabled to Release 10.2 and later, Avaya SBC sets the Passphrase field to default-passphrase by default.
