openssl ts
OpenSSL command to generate and verify timestamps. More information: https://www.openssl.org/docs/manmaster/man1/openssl-ts.html.
- Generate a SHA-512 timestamp request of a specific file and output to
file.tsq:
openssl ts -query -data {{path/to/file}} -sha512 -out {{path/to/file.tsq}}
- Check the date and metadata of a specific timestamp response file:
openssl ts -reply -in {{path/to/file.tsr}} -text
- Verify a timestamp request file and a timestamp response file from the server with an SSL certificate file:
openssl ts -verify -in {{path/to/file.tsr}} -queryfile {{path/to/file.tsq}} -partial_chain -CAfile {{path/to/cert.pem}}
- Create a timestamp response for request using key and signing certificate and output it to
file.tsr:
openssl ts -reply -queryfile {{path/to/file.tsq}} -inkey {{path/to/tsakey.pem}} -signer tsacert.pem -out {{path/to/file.tsr}}
