openssl ts

OpenSSL command to generate and verify timestamps.

• 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}
