If you want to encrypt the BLOB and properties, either in a new or an existing application; the attached implementation guide will help you step by step. The document also includes a deployment plan to make sure the encryption is applied correctly in other environments.

@mowam - Good post on encryption of BLOB data. But I am unable to visualize the usecase in this context. Also, why don't we use the password option for all the properties inside the BLOB and this is also a kind of encryption? Pls help me to understand on password Vs this encrypting option.
1) Instances need to be deleted as class level BLOB encryption check box only gets enabled if there are no instances in the class.
Above is what is recommended OOTB and supported for BLOB from what we are aware of
2) Again Access control policy is the recommended way forward. If you follow approach 1 then when you save a new record then any exposed property will be governed by access control policy. Alternatively for already created work objects you can try creating an access control policy for the exposed property and try and save the BLOB again and see if the exposed property gets encrypted or not.

deleted all instances, created the access control policy for the exposed column. But the varchar column still can be viewed in plain text; i.e. it is not encrypted. I checked the systemout.log file, seems the CustomCipher class is called; saw the "encrypting" and "decrypting" output. Any advise on what could be wrong? How can i check super.encrypt is called?
