Can I ask for a refund or credit next year? Your browser goes down the list until it finds an encryption option it likes and were off and running. This attack (CVE-2016-2183), called "Sweet32", allows an attacker to extract the plaintext of the repetitive content of a 3DES encryption stream.As 3DES block size is only 64-bit, it is possible to get a collision in the encrypted traffic, in case enough repetitive data was sent through the connection which might allow an attacker to guess the cleartext. SOLUTION: Disable and stop using DES, 3DES, IDEA or RC2 ciphers. However, the firewall will still accept 3DES after doing a commit. The main strength lies in the option for various key lengths (AES uses keys of 128, 192 or 256 bits) which makes it stronger than DES. The changes are only involved in java.security file and it will block the ciphers. ::: References Have you tried, Firmware14.0(1)SR2 for 8832.
