Today's release of Securit:ee 1.2 brings additional checks to the Security Scanner, Help Tab documentation support, and the new Encryption Fieldtype.

The Encryption Fieldtype allows Channel Entries and Safecracker form to save data in an encrypted state so sensitive data won't be easily viewable. It's pretty configurable, allowing you to set who can and can not view the raw, unencrypted, value along with the "stand in" text if a user can't view the value.
