Data transmission between your web browser and 5F is encrypted via TLS. For compatibility reasons, TLS 1.2 is set as the minimum level, with AES-128 and SHA-256. If your browser supports it, TLS 1.3 with stronger methods such as AES-256 and SHA-384 is used. Stored data is encrypted (AES-256). If the security assessment of methods changes, we adjust the configuration immediately.
