Hello again, well im reading the documentation, and now i can get the md5 and the base64 convertion, but now I need to sign the md5 with a rsa .key private file, I trying to understand who to do this, viewing on the openssl.org API documentation, but I some confuse, let me explain:
First I initilize a RSA struture like this:
RSA *FirmaDigital;
Then i use the FileIn Stream:
FileIn StreamArchivoFirma;
Get a new Struct of RSA
FirmaDigital=RSA_new();
My cuestion is, who to put the file stream on the memory structure of RSA.
