IntroductionData security, protection of username and password is required not only by Governmental agencies, privatecompanies but ...
The main loop of the AES encryption algorithm performs four different operations on the State matrix, called SubBytes, ShiftRows, MixColumns, and AddRoundKey in the specification. The AddRoundKey operation is the same as the preliminary AddRoundKey except that each time AddRoundKey is called, th...
Encryption algorithms are used to turn data into ciphertext. An algorithm uses the encryption key to alter the data in a predictable way so that, even though the encrypted data will appear random, it can be turned back into plaintext by using the decryption key. There are several different ...
Hashing, in which a unique fixed-length signature is created for a message or data set with an algorithm. Because the signature is unique to the message, even a slight change to its content can create a drastically different hash. It’s different from the previous methods, because once hashe...
The AES Encryption algorithm (also known as the Rijndael algorithm) is a symmetric block cipher algorithm with a block/chunk size of 128 bits. It converts these individual blocks using keys of 128, 192, and 256 bits. Once it encrypts these blocks, it joins them together to form the ciphe...
Two parties (Alice and Bob) could use a hash function to ensure message integrity. They would select a hash algorithm to sign their messages. Alice would write a message, and then create a hash of that message by using the selected algorithm. They would then follow one of the following me...
lists the encryption algorithms that are supported in the Solaris operating system. The table lists the format of the algorithms when the algorithms are used as security options to the IPsec utilities. The table also lists their man page names, and lists the package that contains the algorithm....

"filenames" is the algorithm used to encrypt file names. The choices are "AES_256_CTS", "AES_128_CTS", "Adiantum", and "AES_256_HCTR2". Normally, "AES_256_CTS" is recommended. To use algorithms other than "AES_256_XTS" for contents and "AES_256_CTS" for filenames, the neede...
