Two Decade Old Encryption Software

I wrote the original version of Krypto Zone back in 1999 – debugging C++ code on a shiny VC6 IDE through many sleepless nights. Good old days!

Here is the official and final resting page of an antique, yet still working, piece of encryption software.

Description:

Written entirely in C++, Krypto Zone is a lightweight, fast and user-friendly encryption software. Krypto Zone uses AES-128 and RSA-1024 encryption for privacy. It can be used to sign, encrypt, decrypt and securely erase any files. It also implements secure memory management and sanitization (DOD 5220.22-M) with non-trivial memory allocation mechanism using the Kernel’s page cache.

Features:

  • AES 128-bit symmetric encryption.
  • RSA 1024-bit asymmetric encryption.
  • Secure File Eraser (Clearing and Sanitization Methods DOD 5220.22-M).
  • Self-extracting encrypted files (similar to self-extracting Zip file).
  • The receiver does not need Krypto Zone to open SFX archives.
  • MD5 128-bit.
  • Password manager.
  • Multi file encryption, drag & drop and contextual menu.
  • Text file editor using Memory Mapped Files with Kernel’s page cache and sanitization methods after use.
  • 556 KB size (without documentation).
  • Support from Windows 95 to Windows 10.
