error C4996: 'EVP_PKEY_get1_EC_KEY': Since OpenSSL 3.0 and a few more

L.S.,

When I try to build a program using your library, I still get the following errors:
1>D:\VisualStudioProjects\cpp_jwt\include\jwt\impl\algorithm.ipp(113,24): error C4996: 'EVP_PKEY_get1_EC_KEY': Since OpenSSL 3.0
1>D:\VisualStudioProjects\cpp_jwt\include\jwt\impl\algorithm.ipp(119,9): error C4996: 'EC_KEY_get0_group': Since OpenSSL 3.0
1>D:\VisualStudioProjects\cpp_jwt\include\jwt\impl\algorithm.ipp(264,22): error C4996: 'EVP_PKEY_get1_EC_KEY': Since OpenSSL 3.0
1>D:\VisualStudioProjects\cpp_jwt\include\jwt\impl\algorithm.ipp(271,41): error C4996: 'EC_KEY_get0_group': Since OpenSSL 3.0

What can be the problem?

I'm using OpenSSL-Win64
Win64 OpenSSL v3.0.0 -> downloaded from: https://slproweb.com/products/Win32OpenSSL.html

Regards,

Ruud
