bcrypt
Encrypt and decrypt files using Blowfish
TLDR
Encrypt file
$ bcrypt [file.txt]
Decrypt file$ bcrypt [file.txt.bfe]
Remove original after encryption$ bcrypt -r [file.txt]
SYNOPSIS
bcrypt [options] file...
DESCRIPTION
bcrypt is a file encryption utility using the Blowfish cipher. It encrypts files in place with a password, creating .bfe (Blowfish Encrypted) files.
The tool provides simple command-line encryption for individual files.
PARAMETERS
-r
Remove original file after encryption-c
Compress before encryption
WORKFLOW
$ # Encrypt (creates file.txt.bfe)
bcrypt file.txt
# Decrypt (restores file.txt)
bcrypt file.txt.bfe
# Encrypt and remove original
bcrypt -r file.txt
bcrypt file.txt
# Decrypt (restores file.txt)
bcrypt file.txt.bfe
# Encrypt and remove original
bcrypt -r file.txt
CAVEATS
Older tool with limited maintenance. Password stored in memory during operation. Consider using gpg or age for modern encryption needs. Blowfish superseded by AES in many applications. Files encrypted in place.
HISTORY
bcrypt was created as a simple file encryption tool using the Blowfish cipher, developed by Bruce Schneier in 1993.
