Hi, I'm writing a C++ wrapper library around the OpenSSL API with the intent to not just support SSL for sockets, but as much of the other parts as possible, things like the message digests, encryption/decryption, certificates, etc. So far I have wrapped the core message digests, encryption algos, BIO support, BIGNUM structures and done the basics for RSA key generation and public/private key persistence plus signing and verifying data with them. I am now torn between tackling the ASN API's or simply moving on to the X509 API's. My question is: are the ASN functions worth wrapping? Are they generally useful in and of themselves? I have looked around and found (so far) very little documentation about them. I have found a couple of uses, for example, setting the serial number on an X509 cert structure :
ASN1_INTEGER_set( X509_get_serialNumber(x),serial ); Outside of the internal usage of the API's I haven't seen any other examples of how to use them. As I understand it, ASN is used to describe data structure and also how to encode it. This sounds like it would be a nice thing to have a C++ wrapper for, but I'm kind of clueless on where to begin. The other API's were relatively easy to wrap, as it seemed pretty obvious from either documents or examples what they were supposed to do. If the ASN stuff is worth wrapping would anyone have any suggestions on were else to look to understnad better what needs to be wrapped and how to approach it? I noticed that there was a book from O'Reilly about OpenSSL programming maybe that might have enough info in it.
