OpenSSL 3.0 made EVP_PKEY immutable. This means we can only have a const pointer of the low level struct and the following methods can no longer be provided when linked against OpenSSL 3.0: - OpenSSL::PKey::RSA#set_key - OpenSSL::PKey::RSA#set_factors - OpenSSL::PKey::RSA#set_crt_params - OpenSSL::PKey::DSA#set_pqg - OpenSSL::PKey::DSA#set_key - OpenSSL::PKey::DH#set_pqg - OpenSSL::PKey::DH#set_key - OpenSSL::PKey::EC#group= - OpenSSL::PKey::EC#private_key= - OpenSSL::PKey::EC#public_key= There is no direct replacement for this functionality at the moment. I plan to introduce a wrapper around EVP_PKEY_fromdata(), which takes all key components at once to construct an EVP_PKEY. https://github.com/ruby/openssl/commit/6848d2d969
