This is the command bcrypt that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator

NAME
bcrypt - blowfish file encryption
SYNOPSIS
bcrypt [-orc][-sN] file ...
DESCRIPTION
bcrypt encrypts and decrypts files using the blowfish algorithm.
Encrypted files will be saved with an extension of .bfe. Any files ending in .bfe will be
assumed to be encrypted with bcrypt and will attempt to decrypt them. Any other input
files will be encrypted. If more than one type of file is given, bcrypt will process all
files which are the same as the first filetype given.
By default, bcrypt will compress input files before encryption, remove input files after
they are processed (assuming they are processed successfully) and overwrite input files
with random data to prevent data recovery.
Passphrases may be between 8 and 56 characters. Regardless of the passphrase size, the key
is hashed internally to 448 bits - the largest keysize supported by the blowfish
algorithm. However, it is still wise to use a strong passphrase.
OPTIONS
-o print output to standard out. Implies -r.
-c DO NOT compress files before encryption.
-r DO NOT remove input files after processing
-sN How many times to overwrite input files with random data before deleting. The
default number of overwrites is 3. Use -s0 to disable this feature. No effect if -r
is supplied.
NOTES
The -o ,-r ,and -c options each have the opposite effects if the appropriate settings are
altered from the defaults in config.h. To determine what effect each of these have on your
system, run bcrypt without any options.
Encrypted files should be compatible between most systems. Binary compatibility has been
tested on all supported systems. There is a list of supported systems in the README file
that was included with this software.
