I think I'm loadaing the correct DLL versions.
>From the Visual Studio IDE I can see that the libaye32.dll is loaded
from the debug folder where I copied it.
libeay32.dll D:\work\openssl\ssl_test\debug\libeay32.dll N/A N/A
Symbols
loaded. D:\work\openssl\ssl_test\debug\libeay32.pdb 5 1.00.0.5
25.11.2011
11:34 10000000-10113000 [7580] ssl_test.exe: Native
libeay32.dll is of version 1.0.0.5. I have built it from the source code.
Having the libeay32.pdb file in the same folder I'm able to step into
EVP_DecryptUpdate():
evp_enc.c, lines 426-427:
if (fix_len)
*outl += b;
The "fix_len" flag"is not set during the first decrypt block but is
set during the rest of the blocks as the output of my test program
shows. Because of that increment the output buffer in my program
becomes larger that the original data before it is encrypted.
outp += (olen + tlen); // olen too big here
