MQTT Server

MQTT server:

• mqtts://mqtt-dev-server.westus2-1.ts.eventgrid.azure.net
• port: 8883

Getting server certificate:

openssl s_client -showcerts -connect mqtt-dev-server.westus2-1.ts.eventgrid.azure.net:8883 </dev/null 2>/dev/null|openssl x509 -outform PEM >eventgrid.azure.pem

This produces eventgrid.azure.pem certificate file.

need root certificates

openssl s_client -showcerts -connect www.bigfoot-inc.com:443

openssl s_client -showcerts -connect mqtt-dev-server.westus2-1.ts.eventgrid.azure.net:8883

to get full certificate and save it to pem file: openssl s_client -showcerts -connect mqtt-dev-server.westus2-1.ts.eventgrid.azure.net:8883 </dev/null 2>/dev/null|openssl x509 -outform PEM >mycertfile.pem

openssl s_client -showcerts -verify 5 -connect mqtt-dev-server.westus2-1.ts.eventgrid.azure.net:8883 < /dev/null

openssl s_client -showcerts -verify 5 -connect mqtt-dev-server.westus2-1.ts.eventgrid.azure.net:8883 < /dev/null | awk '/BEGIN CERTIFICATE/,/END CERTIFICATE/{ if(/BEGIN CERTIFICATE/){a++}; out="cert"a".pem"; print >out}' for cert in .pem; do newname=$(openssl x509 -noout -subject -in $cert | sed -nE 's/.CN ?= ?(.)/\1/; s/[ ,.]//g; s/__//g; s/-/-/; s/^_//g;p' | tr '[:upper:]' '[:lower:]').pem echo "${newname}"; mv "${cert}" "${newname}" done

convert crl to pem openssl crl -in "Microsoft Azure ECC TLS Issuing CA 08 - xsign.crt" -inform PEM -out "Microsoft Azure ECC TLS Issuing CA 08 - xsign.pem"
