Full script for getting LEGO SSL certificate for rpxy

[id4vip]

Thanks for making rust-rpxy. I am using rust-rpxy & it is working blazing fast with my self signed certificate. Now I want to use actual ssl certificate through letenscrypt with the help of LEGO. As rpxy use rust format key(PK8) & letenscrypt give key in PK1. It should be very good if some expert person make a bash file which combined the LEGO commands for ssl certificate & convert key file into rust key format. Basically i want to merge creation of key & converting into rust format in one script.

https://go-acme.github.io/lego/usage/cli/obtain-a-certificate/

if some expert make this type of bash script file then we can run that file periodically by Linux Cron job.
thanks

I am not stick with LEGO, i just need any working way to use SSL certificate & rust-rpxy in any script may be use any mechanism as mentioned in another post,

I made one bash file, it should be working, PK1 key creation default way & this bash file generate pk8 file if any change in pk1 & pk8 last modification date. Both pk1 creation & this script runs weekly with linux cron in serial order

#!/bin/bash
if [ "/mnt/userdata/rpxy/certificates/_.XXX.ZZZ.key" -nt "/mnt/userdata/rpxy/certificates/_.XXX.ZZZ.key.pem" ]
then
  echo "Different certificate, updating..."
  cd /mnt/userdata/rpxy/certificates
  openssl pkcs8 -topk8 -nocrypt \
      -in _.XXX.ZZZ.key \
      -inform PEM \
      -out _.XXX.ZZZ.key.pem \
      -outform PEM
   sudo systemctl restart rpxy.service
else
  echo "Same certificate, No change needed"
fi
