using applink.c
So I've spent all week trying to find the answer to no success. I've downloaded and installed the precompiled openssl binaries for windows. My app includes the line: #include openssl/applink.c and compiles correctly. The app runs until openssl code is accessed. Then I get: OPENSSL_Uplink(058A1010,05): no OPENSSL_Applink I've seen comments in the faq about adding: CRYPTO_malloc_init(); but it generates compilation errors. 1c:\users\mluich\documents\visual studio 2008\projects\sr_trillian_plugin\sr_trillian_plugin\sr_trillian_plugin.cpp(21) : error C4430: missing type specifier - int assumed.

Re: Microsoft Visual C++
OK So I figured it out. After following the help files instructions on where to copy the files, under the project properties - configuration properties - linker - input - additional dependencies add libeay32MD.lib ssleay32MD.lib Note the MD matches the build type under properties - configuration properties - C/C++ - code generation Mike Luich On Fri, Oct 10, 2008 at 9:25 PM, Thomas J.

Null termination after encryption.
Hello everyone, here's what's driving me nuts. I'm sure i'm missing
something simple, but why isn't the encrypted message coming out of
BIO_get_mem_data(out, enc_msg); Null terminated ?

Re: Null termination after encryption.
Hmm then perhaps I'm expecting the wong thing to be coming out. I'm using PKCS7_encrypt followed by SMIME_write_PKCS7. So the data is base64 encoded and in S/MIME Format. I just want to get this in a format that I can return as a string that's null terminated. So the app can use it as a string.

It's not a string, it's a block of arbitrary data. Besides, what would be the point in nul-terminating a block of data that may already contains any number of zero bytes in it?

Re: Null termination after encryption.
Ok that makes sense. kinda goes with what I had been thinking, So i just add the null character at the end of the bio before I use BIO_get_mem_data(out, enc_msg); now just how to do that . ssl bio write mike Luich On Fri, Aug 29, 2008 at 1:35 PM, David Schwartz [EMAIL PROTECTED]wrote: Hmm then perhaps I'm expecting the wong thing to be coming out.

So the app can use it as a string. Mike Luich You're right, wrong explanation. The function wrote the string to the BIO, but not the terminator (just as you wouldn't write the terminator to a file). You then got a pointer to the data in the BIO. The same thing would occur if you memory-mapped a file containing the string. It wouldn't be terminated. If you need to the data in the form of a C-style string, you need to make it one. You could simply write a zero to the BIO, I suppose.
