Radmin is fast and secure remote control and remote access software that enables you to work on a remote computer as if you were sitting right in front of it and access it from multiple places. Radmin includes Windows Vista support, file transfer, multi-user text and voice chat, Windows security, Kerberos authentication, 256-bit AES encryption, telnet access, multiple monitors support and unique DirectScreenTransfer technology.

With BCArchive software you may encrypt and compress a group of files/folders
to an encrypted archive (i.e. single file). You may store all you confidential files in such archive accessing it whenever you need it. All your files are encrypted, protected from unauthorized access. You may create self-extracted program containing encrypted archive and e-mail it to your friend. BCArchive uses strong encryption symmetric and asymmetric algorithms.

Puffer is a general purpose 256-bit AES encryption utility for protecting your most sensitive data. Use Puffer to securely exchange email with other Puffer users via the 2048-bit Diffie-Hellman key exchange function. Compress and encrypt your data files into zip-style PUF archives. Use steganography to hide data among the pixels of image files. Distribute self-decrypting archives to non-Puffer users. Permanently erase data with wipe functions.

A security toolkit letting even less experienced programmers add encryption and authentication services to their apps, features that are becoming indispensable. The library hides low-level details of security from developers. It supports a variety of algorithms for symmetric/asymmetric encryption, authentication, and hashing. The library is free for non-commercial/shareware projects. It is written in C. ActiveX and C++ wrappers are available.

With the Open SSL 0.9.7c library, developers can write applications that take advantage of Secure Sockets Layer (SSL v2/v3), Transport Layer Security (TLS v1), and a full-strength general-purpose cryptography library. Security features such as data integrity, authenticity, and privacy can be implemented. To compile for Win32, Perl or compiling under Cygwin is required. Some of the encryption routines/algorithms are covered by patents.
