## Encrypting a Folder

<h2>✉️ Encrypting a Message for Yourself: [Different Method]</h2>
|
||||
<!-- Your content here -->
|
||||
|
||||
1. **Create a tarball from the folder you want to encrypt:**
|
||||
<h3>Encrypting a message for yourself:</h3>
|
||||
|
||||
Replace **`/path/to/folder_to_encrypt`** with the path to your folder and **`archive.tar.gz`** with the desired name for your tarball.
|
||||
<ol>
|
||||
<li><strong>Generate a Key Pair:</strong></li>
|
||||
<code>gpg --gen-key</code>
|
||||
|
||||
\`\`\`bash
|
||||
tar -czvf archive.tar.gz /path/to/folder_to_encrypt
|
||||
\`\`\`
|
||||
<li><strong>Encrypt the Message:</strong></li>
|
||||
<code>gpg -e -u "Your Name" -r "Your Name" message.txt</code>
|
||||
|
||||
2. **Encrypt the tarball using GPG:**
|
||||
<li><strong>Decrypt the Message:</strong></li>
|
||||
<code>gpg -d message.txt.gpg</code>
|
||||
</ol>
|
||||
|
||||
Replace **`your-email@example.com`** with your email and **`archive.tar.gz`** with your tarball's name. This will create an encrypted file named **`archive.tar.gz.gpg`**.
|
||||
<h2>👥 Encrypting a Message for Someone Else:</h2>
|
||||
|
||||
\`\`\`bash
|
||||
gpg -e -r your-email@example.com archive.tar.gz
|
||||
\`\`\`
|
||||
<ol>
|
||||
<li><strong>Import Their Public Key:</strong></li>
|
||||
<code>gpg --import theirkey.gpg</code>
|
||||
|
||||
## Decrypting a Folder
|
||||
<li><strong>Encrypt the Message:</strong></li>
|
||||
<code>gpg -e -u "Your Name" -r "Their Name" message.txt</code>
|
||||
</ol>
|
||||
|
||||
1. **Decrypt the GPG file to a tarball:**
|
||||
<h2>🔄 Exporting & Importing Keys</h2>
|
||||
|
||||
This will decrypt the **`archive.tar.gz.gpg`** file back to **`archive.tar.gz`**.
|
||||
<p><strong>Exporting Your Public Key:</strong></p>
|
||||
|
||||
\`\`\`bash
|
||||
gpg -o archive.tar.gz -d archive.tar.gz.gpg
|
||||
\`\`\`
|
||||
<ol>
|
||||
<li><strong>List your keys to find the one you want to export:</strong></li>
|
||||
<code>gpg --list-keys</code>
|
||||
|
||||
2. **Extract the tarball to the original folder:**
|
||||
<li><strong>Export it to a file:</strong></li>
|
||||
<code>gpg --export -a "Your Name" > public.key</code>
|
||||
</ol>
|
||||
|
||||
This will extract the contents of the tarball to the current directory.
|
||||
|
||||
\`\`\`bash
|
||||
tar -xzvf archive.tar.gz
|
||||
\`\`\`
|
||||
|
||||
Please note that the person performing the decryption and extraction will need the GPG private key that corresponds to the public key used to encrypt the file.
|
||||
|
||||
# Encrypting a message for yourself: [Different Method]
|
||||
|
||||
1. **Generate a Key Pair**: If you haven't already, you'll need to generate a GPG key pair. You can do this with the **`-gen-key`** option:
|
||||
|
||||
\`\`\`bash
|
||||
gpg --gen-key
|
||||
\`\`\`
|
||||
|
||||
Follow the prompts to set your name, email address, and passphrase.
|
||||
|
||||
2. **Encrypt the Message**: You can now encrypt a message with your public key. For example, to encrypt a message in a file named **`message.txt`**, you can use the following command:
|
||||
|
||||
\`\`\`bash
|
||||
gpg -e -u "Your Name" -r "Your Name" message.txt
|
||||
\`\`\`
|
||||
|
||||
Replace "Your Name" with the name you used when generating your key pair. This will create an encrypted file named **`message.txt.gpg`**.
|
||||
|
||||
3. **Decrypt the Message**: To decrypt the message, you can use the **`gpg`** command with the **`d`** option:
|
||||
|
||||
\`\`\`bash
|
||||
gpg -d message.txt.gpg
|
||||
\`\`\`
|
||||
|
||||
You'll be asked for the passphrase you used when generating your key pair.
|
||||
|
||||
# Encrypting a message for someone else:
|
||||
|
||||
1. **Import Their Public Key**: Before you can encrypt a message for someone else, you'll need their GPG public key. Once you have it, you can import it with the **`-import`** option:
|
||||
|
||||
\`\`\`bash
|
||||
gpg --import theirkey.gpg
|
||||
\`\`\`
|
||||
|
||||
Replace "theirkey.gpg" with the filename of their public key.
|
||||
|
||||
2. **Encrypt the Message**: You can now encrypt a message with their public key. For example, to encrypt a message in a file named **`message.txt`**, you can use the following command:
|
||||
|
||||
\`\`\`bash
|
||||
gpg -e -u "Your Name" -r "Their Name" message.txt
|
||||
\`\`\`
|
||||
|
||||
Replace "Your Name" with your name and "Their Name" with the name associated with their public key. This will create an encrypted file named **`message.txt.gpg`**.
|
||||
|
||||
The recipient will then be able to decrypt the message using their private key.
|
||||
|
||||
# Exporting & Importing Keys
|
||||
|
||||
**Exporting Your Public Key:**
|
||||
|
||||
1. List your keys to find the one you want to export:
|
||||
|
||||
\`\`\`bash
|
||||
gpg --list-keys
|
||||
\`\`\`
|
||||
|
||||
2. Once you've identified the key you want to export (it's usually your email address or name), use the **`-export`** option with the **`a`** (armor) flag to export it to a file:
|
||||
|
||||
\`\`\`bash
|
||||
gpg --export -a "Your Name" > public.key
|
||||
\`\`\`
|
||||
|
||||
Replace "Your Name" with the name or email associated with the key you want to export. This will create a file named **`public.key`** containing your public key.
