      When will wolfSSL support DER format of CA certificate? Thanks.

      Individual certificates and private keys can be used in either format, DER or PEM. CA certificates on the other hand must be in PEM format, the SSL_CTX_load_verify_locations() function doesn't allow the option to specify which format and assumes PEM. Is there a reason you need CA certificates in DER format?

      I am new to SSL and X.509. I don't know which of DER and PEM format of CA certificate prevails commercially? If it is PEM, i'm all set; otherwise I will need DER support.

      Please advise. Thanks.

      I can show you how to convert DER to PEM if that's all you can find, it's trivial.

      Thank you.

      Is it by openssl command line?

      Is there any windows executable for the purpose?

      The openssl command line utility is the quickest, easiest way to do it. You should be able to use openssl on Windows, either native or through cygwin. I could build an executable to do it if you really need it, I'd just reverse PemToDer.
