It appears that they are now oudated.When I add the expected header file, I get a #error message to update my software.
What I have tried:
I have and am still searching with google for a solution. ASN1_INTEGER and ASN1_INTEGER_set() are still present.
M_ASN1_INTEGER_new() has been removed. It was a macro and has been replaced by the function ASN1_INTEGER_new() .
It seems that this is an internal function and not intended to be used by applications.
But there should be no need to create certificates programmatically. Just use the OpenSSL command line tools instead.

Read the question carefully.

Understand that English isn't everyone's first language so be lenient of bad spelling and grammar.

If a question is poorly phrased then either ask for clarification, ignore it, or edit the question and fix the problem. Insults are not welcome.

Don't tell someone to read the manual. Chances are they have and don't get it. Provide an answer or move on to the next question. Let's work to help developers, not make them feel stupid.
