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)
