Is this RSA algorithm?

"rsa_eay.c" is part of the OpenSSL package. If OpenSSL is linked to your code, it naturally contains RSA, but also dozens of other crypto algorithms. It doesn't mean the algorithms are actually used for anything.

The calling convention looks strange, it seems to be some exotic compiler (maybe Cygwin?). So you might have to recompile OpenSSL yourself to create IDA signature files.

Yes, I confirm the code call "rsa_eay.c", but I don't know how to deal with it, would you please give a little more details on how to complile OpenSSL and create IDA signature? Is there any post can be referenced? Thanks.
