After some search i found this commit [14c5880](https://github.com/gridcoin-community/Gridcoin-Research/commit/14c5880ab357367b9bcc16c83922ea14796f3cdf) replacing the code in bitcoinrpc.cpp everything builded fine.

I finally managed to build the wallet with OpenSSL v1.1 everything seems to work fine but more tests needed I made a fork and changes are on this commit [486112c](https://github.com/sats0k/Phoenixcoin/commit/486112c1aaaa2df1c6f738bce41ee6423d3195d3)...

I am new to all of this and to avoid any kind of mistake please check the code and if you find it ok i will do a pull request.

I have sync my fork with the base.

These warnings appears on GCC 11.1.0

Testing GCC 12 the warnings became to [-Warray-bounds] ``` inlined from ‘std::string CBase58Data::ToString() const’ at src/base58.h:218:19: /home/k0stas/gcc/include/c++/12.0.0/bits/stl_algobase.h:431:30: warning: ‘void* __builtin_memcpy(void*, const void*, long unsigned int)’ offset 1 is out of...
