Encryption and Decryption cli

Overview

This repository contains two Go programs for file encryption and decryption:

• encrypt.go: Encrypts files using AES256 encryption.
• decrypt.go: Decrypts files encrypted by encrypt.go.

Both programs support the use of a user-specified password for encryption/decryption and the generation of a random AES256 key.

Features

encrypt.go

• Generates an AES256 key and saves it to a file.
• Encrypts files using AES256 encryption.
• Supports encryption of individual files or entire directories.
• Cleans up original files after encryption if specified.

decrypt.go

• Decrypts files encrypted by encrypt.go.
• Supports decryption of individual files or entire directories.
• Cleans up encrypted files after decryption if specified.

Installation

Prerequisites

• Go (version 1.16 or later)

Build

To build the programs, navigate to the directory containing the .go files and run:

go build encrypt.go
go build decrypt.go

This will create two executables: encrypt and decrypt.

Usage

encrypt

Encrypt a single file:

encrypt -f <input_file>  [-kf <key_file>] [-clean]

Encrypt all files in a directory:

encrypt -dir <directory> [-kf <key_file>] [-clean]

Flags

• -f <input_file>: Input file to encrypt.
• -kf <key_file>: File to read/write the encryption key. Defaults to keyfile.key.
• -dir <directory>: Directory containing files to encrypt.
• -clean: Clean up (delete) the original files after encryption.

decrypt

Decrypt a single file:

decrypt -f <input_file> [-kf <key_file>] [-clean]

Decrypt all files in a directory:

decrypt -dir <directory> [-kf <key_file>] [-clean]

Flags

• -f <input_file>: Input file to decrypt.
• -kf <key_file>: File to read the decryption key from. Defaults to keyfile.key.
• -dir <directory>: Directory containing files to decrypt.
• -clean: Clean up (delete) the encrypted files after decryption.

Deployment

To make the executables globally available, move them to a directory that is included in your system's PATH.

Linux/macOS

sudo mv encrypt /usr/local/bin/
sudo mv decrypt /usr/local/bin/

Windows

Move the encrypt.exe and decrypt.exe files to a directory included in your PATH. For example, C:\Windows\System32.

move encrypt.exe C:\Windows\System32
move decrypt.exe C:\Windows\System32
