Hybrid Cryptography Algorithm v1.0.0

First public release of Hybrid Cryptography Algorithm: encrypt text files with AES and DES, alternating per block.

• Encrypt any .txt file with a fresh random AES and DES key, shown as one hybrid key
• Decrypt it back exactly, for text in any language
• About window with project links, and an update check that only asks GitHub for the latest release

Install: download the zip, unzip it, and run HybridCryptographyAlgorithm.exe. Needs Windows 10 or 11, 64-bit; nothing to install.

For learning only: DES is broken and the keys aren't generated securely, so don't use it for real data. See SECURITY.md.

The exe isn't code-signed, so SmartScreen may warn you the first time: choose More info, then Run anyway.
