Dear OpenSSL users, we want to want to operate on the Contents of a memory BIO - eg digest - and tried out following implementation:
------------- BIO *mb = BIO_new(BIO_s_mem()); // filling it with some data char* message="This is some data to digest"; BIO_write(mb, message, sizeof(message)); // after the memory bio has been filled BIO *dg = BIO_new(BIO_f_md()), *nul=BIO_new(BIO_s_null()); EVP_MD *md = EVP_md5(); BIO_set_md(dg,md); // get all out of the mb and diget it BIO_push(mb,dg); // append digesting to mem-BIO BIO_push(dg,nul); // get all out of digest-BIO // BIO chain should be: mem-dgst-nul // get the digest now char mdbuf[EVP_MAX_MD_SIZE]; BIO_gets(dg, mdbuf, EVP_MAX_MD_SIZE); ------------- but the memory BIO stays filled, even after performing BIO_flush(mb) and the digest we get out of dg is the digesting start value. So what am I missing? How can the propagation of the memory data through the filter BIO be triggered?
