Secure ciphers are considered state-of-the-art. Recommended ciphers also provide Perfect Forward Secrecy (PFS) and should be preferred. Weak ciphers are only offered to provide support for older operations systems, browsers, or applications. However, they are old and should be avoided. Furthermore, they are deprecated and will not be offered in the near future.
