This script automates the process of signing a binary with GPG, generating a timestamp for both the binary and signature, and uploading the files to GitHub. Additionally, it provides a message containing the SHA256 hash of the binary and instructions for verifying the timestamp files.

• Signs a binary using GPG.
• Generates a timestamp for both the binary and the signature.
• Uploads the signed binary, signature, and timestamp files to GitHub.
• Outputs a message with the SHA256 hash and verification instructions.

1. Ensure you have GPG and keys available.
2. Run the script with your binary as input.
3. The script will generate the following files:
   • The original binary
   • The GPG signature (.sig)
   • The timestamp files (.ts1, .ts2)
4. These files are uploaded to a GitHub repository.
5. A message containing the SHA256 hash and verification details will be provided.

• To verify the GPG signature:

  gpg --verify binary-file.sig binary-file
