    227227== How to implement ==
    228 To implement the changes in hashing and encryption, you need to perform conversions while users are offline from the system. The number of conversions you have to perform depends on the number of packages that use these features. In the world outside of the VA, these most likely will be the TIU and Radiology/Nuclear Medicine packages, results in two conversions in addition to that of hashing the electronic signature.

    230230As hashing is a lossy operation, it can only be done once from the plain text. To hash electronic signatures, you need to perform a loop on the new person file like this:
