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.
