DirectAccess and Null Cipher Suites - KamHussain.com
The update to the priority order for cipher suites used for negotiating TLS 1.2 connections on JDK 8 will give priority to GCM cipher suites. GCM cipher suites are considered more secure than other cipher suites available for TLS 1.2. Later versions of the JDK already prefer GCM cipher suites before other cipher suites for TLS 1.2 negotiations. null-cipher (Andrew M) · GitHub null-cipher Follow. Andrew M null-cipher. Pro.

Jun 04, 2018 · The Null Cipher is used by its practitioners to conceal the very existence of a cipher. The only cipher that cannot be solved is the one that no one knows exists. The plaintext is disguised by words looking every bit the same as ordinary text.
Null Cipher: A null cipher is a type of hidden message where the real message is “camouflaged” in an innocent sounding message. A famous example of a null cipher is one sent by a German Spy in WWII: Apparently neutral’s protest is thoroughly discounted and ignored. Isman hit hard. Blockade issue affects

Cipher suites not in the priority list will not be used. Allowed when the application passes SCH_USE_STRONG_CRYPTO: The Microsoft Schannel provider will filter out known weak cipher suites when the application uses the SCH_USE_STRONG_CRYPTO flag. RC4, DES, export and null cipher suites are filtered out. The title of the post also mentions about NULL authentication Actually the method to enable NULL authentication is also similar to NULL encryption but with a trick. If you want to disable authentication, then it is sufficient not to set the authentication as below. The NullCipher class is a class that provides an "identity cipher" -- one that does not tranform the plaintext. As a consequence, the ciphertext is identical to the plaintext. All initialization methods do nothing, while the blocksize is set to 1 byte. The use more resembles a code function than a cipher, though. Either way, it is definitely a form of steganography. Because the volume of mail was so large, 20th century wartime postal censors were presented with the hard task of trying to catch suspicious wording that could contain a null cipher.
