Does anyone know of a way to reverse encryption on attachments?

[John VanBruggen]

I am looking for a way to remove encryption context from a large number of attachments in relation to a specific table.

Is there a way to do this?   I see scripts in the WIKI that show how to encrypt en mass but nothing for removing encryption.

Thanks in advance.

I'm not sure what the parameters are, but these are all accessible methods of GlideSysAttachment.

Maybe something in here can help?

This is great.   Where did you find this list?   I find very little info about glidesysattachment as far as usage goes.

Hi John,

There is some info here:

Useful Attachment Scripts - ServiceNow Wiki

..

Note: This API call changed in the Calgary release:

• GlideSysAttachment replaces Packages.com.glide.ui.SysAttachment

etc

Best Regards

Tony

Thanks, I seen this out there too but it really doesn't give much on it.

The only use case it describes is GlideSysAttachment.copy.

I am really interested in how to utilize GlideSysAttachment.changeEncryptionContext

I've successfully applied an encryption context previously, however I'm not certain if it can be removed completely. Perhaps a null value?

var ga = new GlideSysAttachment();
ga.changeEncryptionContext(tableName, recordSysID, attachmentSysID, encryptionContextID);
