Openssl / Generate Sha512 Timestamp Request
Generate Sha512 Timestamp Request
Generates a SHA-512 timestamp request from a specified file.
openssl ts -query -data <path/to/file> -sha512 -out <path/to/file.tsq> openssl ts -query -data <path/to/file> -sha512 -out <path/to/file.tsq> #!/bin/bash
# Generate Sha512 Timestamp Request
openssl ts -query -data {{path/to/file}} -sha512 -out {{path/to/file.tsq}} import subprocess
# Generate Sha512 Timestamp Request
# Make sure to replace <placeholders> with actual values

run_command() When To Use
When creating timestamping requests for integrity verification of file uploads
Pro Tip
Ensure the timestamp authority is reachable for valid responses during the process.
Command Builder
Tune the command before you copy it
openssl ts -query -data <path/to/file> -sha512 -out <path/to/file.tsq> Anatomy of Output
Understanding the result
Requested timestamp: /path/to/your/file.txt Request Confirmation Confirms generation of the timestamp request for specified file.
Troubleshooting
Common pitfalls
failed to open file
Solution: Verify the specified file path is correct and accessible.
unable to write to output
Solution: Ensure write permissions for the specified output path.
error generating request
Solution: Check OpenSSL configuration and availability of necessary libraries.
