Installation

Pre-built Binaries

For quick installation, you can download the pre-built binaries for your operating system:

Ubuntu

wget https://amulyaparitosh.github.io/GoCrypt/build/ubuntu/gocrypt
chmod +x gocrypt
sudo mv gocrypt /usr/local/bin/

Windows

1. Download the executable from this link.
2. Add the directory containing gocrypt.exe to your system's PATH environment variable.

Building from Source

If you prefer to build the tool from source or want to contribute to its development, follow these steps:

1. Ensure you have Go installed on your system. If not, download and install it from the official Go website.

2. Clone the repository:

   git clone https://github.com/AmulyaParitosh/GoCrypt.git

3. Navigate to the project directory:

   cd GoCrypt

4. Build the project:

   go build -o gocrypt .

   This will create an executable named gocrypt in your current directory.

5. (Optional) Move the executable to a directory in your PATH for easy access:

   sudo mv gocrypt /usr/local/bin/

Usage

GoCrypt is designed to be simple and straightforward to use. Here's the general syntax:

gocrypt <command> [arguments]

Commands

• encrypt: Encrypts a file given a password
• decrypt: Tries to decrypt a file using a password
• help: Displays help text

Basic Usage

To encrypt a file:

gocrypt encrypt /path/to/your/file

To decrypt a file:

gocrypt decrypt /path/to/your/encrypted/file

To display help:

gocrypt help

Examples

1. Encrypting a file:

   gocrypt encrypt /home/user/documents/secret.txt

   You will be prompted to enter a password for encryption.

2. Decrypting a file:

   gocrypt decrypt /home/user/documents/secret.txt.encrypted

   You will be prompted to enter the password used for encryption.

3. Displaying help information:

   gocrypt help

Security Considerations

• GoCrypt uses the SHA-1 algorithm for encryption. While SHA-1 is considered cryptographically broken for digital signatures, it can still provide a reasonable level of security for file encryption in many scenarios.
• Always use strong, unique passwords for each file you encrypt.
• Remember that the security of your encrypted files depends on the strength of your password and how well you protect it.
• For highly sensitive data, consider using more advanced encryption tools or consult with a security expert.
