Hello. When I read the RSA private key file created with the ssh-keygen command that comes with Windows 10 with the PEM_read_PrivateKey() function, the following error occurred. error: 0906D06C: lib(9): func(109): reason(108) The platform is CentOS7, OpenSSL 3.0.5. Is the private key file created with Windows 10 not supported? How can I use the private key file created in Windows 10 as well? best regards, thank you Setsuo Imazu
