v10 v11 226 226 227 227 == 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.228 To implement the changes in hashing and encryption, you need to perform conversions while users are offline from the system.

To hash electronic signatures, you need to perform a loop on the new person file like this: … … 390 390 391 391 = Appendix 1: How does TIU encrypt the signature blocks = 392 TIU encrypts these fields in file TIU DOCUMENT ( #8925)392 TIU encrypts these fields in file TIU DOCUMENT (!#8925) 393 393 {{{ 394 394 1503 SIGNATURE BLOCK NAME
