Caching-sha2-password.dll - ((better))

The "caching" aspect of the file name is not just for show. In high-traffic environments, the computational cost of repeatedly hashing passwords for frequent connection attempts can be significant.

| Variable | Description | | :--- | :--- | | caching_sha2_password_auto_generate_rsa_keys | Auto-generate RSA keypair if missing. | | caching_sha2_password_private_key_path | Path to RSA private key file. | | caching_sha2_password_public_key_path | Path to RSA public key file. | | default_authentication_plugin | Must be caching_sha2_password to use this DLL by default. | caching-sha2-password.dll

caching-sha2-password.dll is a critical security component in MySQL 8.0+ deployments. It balances (SHA-256) with performance via an intelligent caching mechanism. Administrators must ensure client compatibility and proper protection of RSA private keys. For legacy environments, fallback to mysql_native_password is possible but not recommended for new deployments. The "caching" aspect of the file name is not just for show

This reduces security. Do this only for legacy applications and never for administrative accounts. | caching-sha2-password
