SecureDELTA APP creates industrial-strength secure software updates. It gives users the ability to sign SecureUPDATE Files (SecureDELTA and XtremeDELTA binary diff files), encrypt SecureUPDATE Files (BlowFish 448bit Encryption), create different signing keys for different software product updates and review SecureUPDATE files before deploying. Users may also deploy secure updates using Secure Self-Extracting files (SecureSFX). SecureDELTA comes with new SecureSFX types: SecureCMDLine Self-Extracting Installer and SecureWIZARD Self-Extracting Installer.
