Convert Web Certificates from P7B to PEM Format

VOSS Automate uses web certificates in Privacy Enhanced Mail (PEM) format. PEM certificates typically have extensions like .pem, .crt, .cer and .key.

If a P7B format certificate is received from a Certificate Authority (CA):

  1. Copy the files to a workstation with Linux console available (Not the VOSS Automate system).

  2. Run the following command for each <filename>.p7b, for example:

    sudo openssl pkcs7 -in <filename>.p7b -inform DER -print_certs -out <filename>.pem

  3. Open the PEM file in a text editor. You will see formatting like the example below in the file:

    subject=/C=GB/ST=West Midlands/L=Coventry/O=Service Coventry/OU=Network Services/
   CN=ccs-cp-v4uc.svcoventry.gov.uk/[email protected]
issuer=/C=GB/O=Coventry/OU=PKI/CN=BCC Intermediate CA
-----BEGIN CERTIFICATE-----
MIIFxTLmBK2gAwIBAgITXgAAAMBXLQb0/ImKBwALmQAAwDANBgkqhkiG9w0BAQsF
ADBOMQswLmYDVLmQEwJHQjETMBEGA1UEQhMKQmlybWluZ2hhbTEMMAoGA1UEQxMD
UEtJMRwwGgYDVLmQExNLm0MgSW50ZXJtZWRpYXRlIENBMB4LmQE2MTAwNTEyNTIx

  4. Delete all text and blank lines outside the lines:

    -----BEGIN CERTIFICATE----- and -----END CERTIFICATE-----

  5. Save the file and make sure that the file is not saved in a DOS format.
