2. Open a Command Prompt or Terminal
   Open either:
   • Windows: Command Prompt or PowerShell
   • Linux/macOS: Terminal
   Change to the directory containing both:
   • public_key.asc
   • The file(s) you wish to encrypt
   Example:
   cd /path/to/your/files

   ---

3. Import the Public Key
   Import the public key into your local GPG keyring:
   gpg --import public_key.asc
   
   You should receive a message indicating that the key was successfully imported. Verify the Key

   ---

4. Verify the Key
   Confirm that the key has been imported correctly:
   gpg --list-keys
   
   Look for the recipient:
   productsecurity@ott.com

   ---

5. Encrypt and Sign the File
   To encrypt a file named filename.txt, run:
   gpg --encrypt --recipient productsecurity@ott.com filename.txt
   
   This command will:
   • Encrypt the file using the Ott Product Security public key.
   • Create an encrypted output file named:
   filename.txt.gpg

   ---

6. Send the Encrypted File
   Attach the generated .gpg file to your email and send it to the Ott Product Security team along with other information requested to email: productsecurity@ott.com
   
   Example:
   filename.txt.gpg
   
   Only the holder of the corresponding private key can decrypt the file.
