Contributions summary:Alexander primarily focused on improving the integration with OpenSSL within the SSH library. Their work involved replacing calls to OpenSSL FILE-pointer functions with BIO-based arguments, which resolved Windows DLL boundary issues. Additionally, they refactored the code to pass private keys to OpenSSL using filenames with BIO_new_file(), eliminating the need for the library to read the private key into memory. These changes aimed to enhance the library's compatibility and security related to private key handling.
