Palcrypt

PalCrypt is an open source, bare-bones single file encryption and decryption program. The source code and the installer of the software were released by Pal Microsystems in April 24, 2008 on their site. Unlike other software of the kind, PalCrypt (along with AxCrypt) managed to appeal to both computer programmers/software developers and new users to file encryption by combining strong encryption methods and algorithms such as AES, the less common IDEA, MD5, SHA-1 and Blowfish with a clean graphical user interface and a simple design, fully integrated in Windows Explorer. In addition, developers offered a forum providing information to novice users and on-line support as well. As of August 2009, PalCrypt's publishers stopped developing, supporting and hosting their encryption software. However, since there's a lot of people using some version of PalCrypt (the latest and most popular version is 2.1.1.9), it is still hosted in the major software download websites like Download.com or Softpedia.com etc.
