Не мучайтесь с PKCS12, сделайте проще
Цитата:
PKCS #7 certificate files: These are text certificate files that have .p7b or .p7c filename extensions. These files contain the text: -----BEGIN CERTIFICATE----- and -----END CERTIFICATE----- or -----BEGIN PKCS7----- and -----END PKCS7-----. A certificate authority might include a chain of certificates file that also needs to be installed along with the actual binary certificate file.

По-моему, можно просто слепить всё в текстовом виде в один файл.
