I'm trying to update a crypto library for crtmpserver
to work with openssl 1.1.0. The software is no longer
actively maintained and my c++ skills are somewhat
rudimentary but I keep getting a compilation error for
something that seems trivial.
Here's the code snippet:
bool DHWrapper::CopyPublicKey(uint8_t
*pDst, int32_t dstLength) {
if (_pDH == NULL) {
FATAL("DHWrapper not initialized");
return false;
}
BIGNUM *_keyPublic,*_keyPrivate;
_keyPublic = BN_new();
_keyPrivate = BN_new();
DH_get0_key( _pDH, *_keyPublic, *_keyPrivate );
Use '&' instead of '*'
-Ben
CopyKey(_keyPublic, pDst,
dstLength);
return true;
}
Here's the compilation error:
/build/crtmpserver/src/crtmpserver/sources/common/src/utils/misc/crypto.cpp:

What
am I doing wrong? Thanks,
