Upgrading Encryption
To do one of the following, you must run an upgrade script that modifies the encryption for the field:
Use the RSA or AES encryptor service on a field that Siebel CRM previously did not encrypt or that the Standard Encryptor encrypted. Siebel CRM no longer supports Standard Encryptor.
Use a stronger version of RC2 encryption than Siebel CRM previously used on the field.
For more information, see the upgrade guide for the operating system you are using.
