Encrypted File Container

EFC is a simple system designed for encrypting individual files. Files are encrypted and wrapped in a header that stores the cipher details and original filename.

Features:

• Supports both password-based keys (hashes the password string) and keyfiles
• Supports optional compression using zlib

Currently supported encryption schemes:

• AES 256-bit CFB Mode

Usage:

Three binaries are included:

• efcencode - encrypts files
• efcdecode - decrypts files
• efcinfo - displays header information about an encrypted file

Build dependencies

Building from source requires the following libraries:

• Crypto++
• libsimple-base (from the assorted-utils repo)
• Zlib
