WebJul 31, 2024 · Summary. A vulnerability scan of the ACOS management interface indicated that the HTTPS service supported TLS sessions using ciphers based on DES and IDEA algorithms which are no longer recommended for use with TLS 1.2. Accordingly, the following vulnerabilities are addressed in this document. Item. WebThe Vigenère cipher is an improvement of the Caesar cipher, by using a sequence of shifts instead of applying the same shift to every letter. A variant of the Vigenère cipher, which uses numbers instead of letters to describe the sequence of shifts, is called a Gronsfeld cipher. Gronsfeld ciphers can be solved as well through the Vigenère tool.
