The Ultimate Safety of Blowfish Cipher for Backup Software

Blowfish encryption is implemented a keyed, symmetric cryptographic block ciphering algorithm designed by amazing talent Bruce Schneier in 1993 and placed in the public domain.

Today, blowfish is included in a large number of cipher suites and encryption products. Blowfish’s security has been extensively tested and proven. The best encryption software is based on blowfish cipher. Let’s consider the reasons.

• As an accessible to public cipher, Blowfish has been subject to a significant amount of cryptanalysis, and full Blowfish encryption has never been broken.
• Blowfish is also one of the fastest block ciphers in public use, which functions on a wide variety of processors found in mobile phones as well as in notebook and desktop computers.

The last fact makes it ideal ciphering tool for a products like Handy Backup.

The Awesomeness of Blowfish Code

Schneier designed Blowfish as a general-purpose algorithm, intended as a replacement for the aging DES and free of the problems associated with other algorithms. Notable features of the design include key-dependent S-boxes and a highly complex key schedule.

Blowfish is one of the fastest block ciphers in widespread use, except when changing keys. Each new key requires pre-processing equivalent to encrypting about 4 kilobytes of text, which is rather slow. This prevents its use in some kind of applications, but is not a problem in Handy Backup.

Mostly all versions of Handy Backup maintain ciphering with Blowfish. It’s too simple to use it: you just have to enter the password, and it will be used as a key to all your files and folders encryption in a certain backup session. Just don’t forget the password – decryption may take the centuries.
