blowcrypt

Blowcrypt is a powerful and reliable file encryption software that is built around the advanced blowfish algorithm. This utility offers a convenient Tk frontend that facilitates user-friendly navigation and easy use, but can also be operated from the command line for more advanced users. The software offers robust security with a key length of up to 448 bits, which is the maximum permitted by blowfish algorithm.

The software is designed to be modular, featuring the blowcrypt and RSA Data Security base modules, which offer robust encryption, key hashing, and authentication features using C++ and C languages. Additionally, there are the encrypt and decrypt Perl scripts that interact with the base programs. These can be easily called from any script or cronjob, making it easy to administer the encryption of large file systems.

Finally, the software also comes with a GUI frontend called tkblow, which enables users to perform multiple file selection for encryption and decryption. The software has been successfully tested on Linux (2.2-20-12 Redhat 6.1), and requires the following; Linux OS perl 5 and Tk 8, as well as a C and C++ compiler, which users can get from the standard RedHat distro (GNU GCC and G++).

Overall, Blowcrypt is a reliable and robust software that offers advanced security features and easy administration of encryption of large file systems. The software is released under GNU GPL, and users can rest assured of comprehensive support and updates from the community.
