+Export all certificates into one file
+
+```bash
+$ base64 -d <P7B_FILE>.p7b | openssl pkcs7 -inform DER -print_certs -out <PEM_FILE>.pem
+```
+
+We'll get three certificates inside `<PEM_FILE>.pem` file, from top to bottom:
+1. Certificate for the route in PEM format
+2. CA certificate chain for the route validation in PEM format
+3. Root CA certificate in PEM format
+
+Validate key - certificate pair with following commands
+
+```bash
+$ openssl pkey -in <PRIVATE>.key -pubout -outform pem | sha256sum
+```
+Example output: **bb912b1c6614a0462556b2826b7dce6083a9b58049008a656706234d45abd4c6**
