OpenSSL uses the RSA algorithm for public-key encryption. The RSA key length (size in bits) is controlled with the General.RSAKeySize parameter, see General section.
To modify the RSA key size, complete the following steps:
1 Shutdown the server.
2 Modify the General.RSAKeySize parameter in the solid.ini configuration file.
3 Restart the server.
If the value of the General.RSAKeySize parameter is invalid, the server fails to start and outputs the following error message:
Server process has encountered an internal error and is unable to continue normally. Crypto library enabled, but RSA key size is invalid. Check the value.
