Create Timestamp Response From Request

Create a timestamp response from a request using OpenSSL for secure time validation.

Terminal

openssl ts -reply -queryfile <path/to/file.tsq> -inkey <path/to/tsakey.pem> -signer tsacert.pem -out <path/to/file.tsr>

openssl ts -reply -queryfile <path/to/file.tsq> -inkey <path/to/tsakey.pem> -signer tsacert.pem -out <path/to/file.tsr>

#!/bin/bash

# Create Timestamp Response From Request
openssl ts -reply -queryfile {{path/to/file.tsq}} -inkey {{path/to/tsakey.pem}} -signer tsacert.pem -out {{path/to/file.tsr}}

import subprocess

# Create Timestamp Response From Request
# Make sure to replace <placeholders> with actual values
def run_command():
    cmd = [
        "openssl",
        "ts",
        "-reply",
        "-queryfile",
        "<path/to/file.tsq>",
        "-inkey",
        "<path/to/tsakey.pem>",
        "-signer",
        "tsacert.pem",
        "-out",
        "<path/to/file.tsr>"
    ]
    
    try:
        print(f"Executing: {' '.join(cmd)}")
        subprocess.run(cmd, check=True)
    except subprocess.CalledProcessError as e:
        print(f"Error: {e}")
    except FileNotFoundError:
        print("Error: openssl not found. Please install it first.")

Command Breakdown

What each part is doing

openssl: Base Command; The executable that performs this operation. Here it runs Openssl before the shell applies any redirect operators.
<path/to/file.tsq>: Input Files; The file path or paths supplied to this command.
<path/to/tsakey.pem>: path to tsakey.pem; The value supplied for path to tsakey.pem.
<path/to/file.tsr>: Input Files; The file path or paths supplied to this command.
-reply: Command Option; Tool-specific option used by this command invocation.
-queryfile: Command Option; Tool-specific option used by this command invocation.
-inkey: Command Option; Tool-specific option used by this command invocation.
-signer: Command Option; Tool-specific option used by this command invocation.
-out: Command Option; Tool-specific option used by this command invocation.

How To Run

Execution path

Step 1
Prepare your timestamp request file (.tsq).
Step 2
Run the OpenSSL command with the appropriate paths.
Step 3
Check the output file for the generated timestamp response (.tsr).
