# Encrypting Data Using the Sentinel LDK Data Protection Utility

The Sentinel LDK Data Protection utility (also known as DataHASP) is used to encrypt existing data files that will be delivered together with and accessed by binaries protected by Sentinel LDK Envelope. After data files are encrypted, only binaries that have been protected using Sentinel LDK Envelope can decrypt and access them.
