How to convert certificate from .pem to .der format
I want to know the openssl APIs to convert a certificate from .pem to .der format. I know about the openssl command which does the same. But Can you tell me how to do it in a Cprogram using openssl or any other method -- View this message in context: http://www.nabble.com/How-to-convert-certificate-from-.pem-to-.der-format-tp19722997p19722997.html Sent from the OpenSSL - User mailing list archive at Nabble.com. __ OpenSSL Project http://www.openssl.org User Support Mailing Listopenssl-users@openssl.org Automated List Manager [EMAIL PROTECTED]

(joke)You can also use syscall (/joke) __ OpenSSL Project http://www.openssl.org User Support Mailing Listopenssl-users@openssl.org Automated List Manager [EMAIL PROTECTED]

There is an apps directory in the openssl source tarball. That is a gud starting point to dig for the api's ur looking for. -ugen praveens wrote: I want to know the openssl APIs to convert a certificate from .pem to .der format.
