Extract all certificate chain from .p7b file
Raw
HOWTO.md

Export all certificates into one file

$ 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

$ openssl pkey -in <PRIVATE>.key -pubout -outform pem | sha256sum

Example output: bb912b1c6614a0462556b2826b7dce6083a9b58049008a656706234d45abd4c6

$ openssl x509 -in <ROOT_CA>.cer -pubkey -noout -outform pem | sha256sum

Example output: bb912b1c6614a0462556b2826b7dce6083a9b58049008a656706234d45abd4c6
