Please only use POST. Example usage on Linux/macOS: 

openssl rand 512 | openssl ts -query -data - -cert -sha512 | curl --data-binary @- https://rfc3161.ai.moda -o - -v | openssl ts -reply -text -in /dev/stdin

To get the certificates used in an existing timestamp response file, you can use the following commands:

openssl rand 512 | openssl ts -query -data - -cert -sha512 | curl --data-binary @- https://rfc3161.ai.moda -o rand_response.tsr -v
openssl ts -reply -in rand_response.tsr -token_out -out rand_response.tsr.pkcs7
openssl pkcs7 -inform DER -in rand_response.tsr.pkcs7 -print_certs -text

You can see the list of servers used at:
https://rfc3161.ai.moda/servers.json

We recommend using https://rfc3161.ai.moda (instead of any specific server URL), as this load balancer will automatically pick the fastest and most suitable timestamping server for your application.
