BilboCrypt - encryption program
Program description
Bilbocrypt is freeware file encryption program available under GPL license. By downloading or using the program you agree with license.
BilboCrypt is using Blowfish, Twofish, Rijndael (AES) and Cast128 ciphers (user choosable, multiple encryption passes can be used) in CBC mode.
Dos, Win32 and Linux version is available. Command line syntax is somewhat similar to rar, ace, uharc, 7zip, arj etc..
Without password nobody can discover number, size or names of files in archive, neither their content.
Program uses 576 bit key generated by hash functions SHA-1, RIPEMD-160 and Haval 256, however safety of your data depends on password selection.
If you pick short guessable password like "beer", you can count on you secret files to be public next day if someone gets such encrypted archive.
However 15 character password should be enough for some security (but the longer, the better).
Used ciphers
| Cipher | Twofish | Blowfish | Rijndael (AES) | Cast128 |
| Speed (Win32 version) | 11.7 Mb/sec | 6.6 Mb/sec | 5.2 Mb/sec | 9.4 Mb/sec |
| Maximum key length | 256 bits | 448 bits | 256 bits | 128 bits |
| Block length | 128 bits | 64 bits | 128 bits | 64 bits |
| patented? | no | no | no | no |
Speed is measured on AMD Duron 750 Mhz.
The speed is just a reference point, real speed will also depend on speed of disk and other components.
Program will need about 300 Kb of memory and at least 386 processor (although this will negatively impact on its speed).
Win32 version work on Windows 95, 98, ME, NT, 2000 and XP, but not on Windows 3.11
Linux version work on Linux, it is posible that it might run also on other unixes
(like FreeBSD), however I have not tried it.
Because none ot the used ciphers in the program are patented, you can encrypt anything with BilboCrypt
entirely legally and freely without limits.
Download
Note: if you don't know what "console version" is, download the GUI version.
DLL library is BilboCrypt version for programmers - you can use Bilbocrypt in other programs...
Language (english, czech) is switchable in configuration.
Version 0.97
Version 0.96
Note: For older versions there is only source code available, no binaries, however BilboCrypt is backward compatible, so you shouldn't need them.
