FILECRYPT

⚠ Help Wanted on porting filecrypt to other programing languages
NOTE: if you are planning to use filecrypt for your go-lang project please clone this repo and build your software from there

What's the difference

  • Speed
  • Simple
  • Works on all operating systems

How to use

Windows

  1. Download the latest release from here
  2. Create a folder named "filecrypt" in any drive
  3. Move the downloaded executable(.exe) to the folder created in step 2
  4. Add the path of the created folder created in step 2 into windows path variable
  5. Open the command prompt and enter filecrypt --help for detailed info about using flags

flags

  • --force - Force write even if a file exists with that name (overwrite) DESTRUCTIVE
  • --location - The location of the file to encrypt/decrypt(determined by the mode flag)
  • --mode - FileCrypt mode (encrypt/decrypt These can be replaced with their first letters) Example: filecrypt --mode=e --location="super secret file.txt" --password="test"
  • --password - (removed in release v2 & later) Password to be used while encrypting/decrypting
    Note: due to security issues with commandline flags the password will be prompted at runtime.

Q&A

How can I help?

  • Staring this project on github
  • Creating issues
  • Contributing with code or documentation
  • Sharing this project with your friends

What is a .fcef file

fcef (File. Crypt. Encrypted. File) is an encrypted file that is generated by FileCrypt, If you know the password that it was encrypted with it can be decrypted with FileCrypt using the --mode=dor --mode=decrypt flag.

How is FileCrypt so small

Because Filecrypt

  • Only uses the standard library
  • Has no unwanted code
  • Is built with -ldflags "-s -w" flag
  • Executable is compressed with upx (Only extra small binaries)

    Refactor and simplify codebase

    Hi,

    I saw this repo and thought it was quite interesting. After looking at the code I thought there were a few potential improvements.

    This isn't an attempt to slam you or this project, rather I'm trying to promote best practices and help simplify the code as much as possible.

    This PR:

    • Moves some code around so as it follows a more generic "go-like" structure.
    • Removes some go-routines. You were doing things one at a time and waiting for the routine to finish - the go routines were unnecessary.
    • Uses error + result propagation so as main.go is the only thing that generates output.

    If you've got any questions, please ask!

  • Update main.go

    Update main.go

    to
