abylon BASIC 7.0
The security of sensitive data is often neglected. But the encryption of diaries, pictures or other secret documents with the AES or Blowfish algorithm is so simply. abylon BASIC is a collection for encryption, signing, compressing, searching, copying or moving of files and folders. For the encryption the software supports the blowfish- and AES encryption algorithm and passwords, smart cards, certificates and USB sticks as secret.

Cryptosystem ME6 8.21
Cryptosystem ME6 is a Windows program which uses a symmetric key encryption system to encrypt information in either a single file or in multiple files (at once) so that it cannot be read by those not knowing the key. Data is encrypted using a key which is from 16 to 64 characters long, and which can be either a phrase or a sequence of 64 random bytes (the software provides a way for you to generate such random keys).

AxCrypt 1.6.4.4
Easy to use strong file encryption, integrated with Windows Explorer. Encrypt, compress, decrypt, wipe, view and edit with a few mouse clicks. Cryptographic primitives are AES-128 and SHA-1. A combination of strong symmetric encryption with compression and double-click editing/viewing. Encrypted files have a '.AXX' extension added to their names, and are shown with a new icon.

LTFCrypt 1.1
Would you like to use C++ to build your own file encryption program? This real-world example source code package contains a fully functional program that encrypts and decrypts text or binary files. This is an easy way for you to learn how to use Visual C++ with LibTomCrypt, a public domain and an ISO C cryptography library, to build your own file encryption program.
