Review of Short Phrases and Links

    This Review contains major "Bytes"- related terms, short phrases and links grouped together in the form of Encyclopedia article.

Definitions

  1. If bytes are removed or lost from the file or stream in ECB, CBC and OFB modes, are impossible to recover, although CFB mode will recover. (Web site)
  2. If bytes are summed, then the addition is modulo 256 since there are eight bits to the byte and the sum ranges from 0 to 255. (Web site)
  3. The pad bytes are all the same and are set to a byte that represents the number of bytes of padding.
  4. Code bytes are the output of encoding or encryption processes.
  5. Input bytes are read into the second half of the window, + * and move to the first half later to keep a dictionary of at least wSize + * bytes.

  1. In each round, the algorithm passes over the entire plaintext n times, where n is the length of the plaintext in bytes. (Web site)

Key Schedule

  1. This parameter takes a binary string of 8 bytes in length and is used to generate the key schedule. (Web site)
  2. It encrypts or decrypts the bytes in in using the key schedule, putting the result in out. (Web site)

First Packet

  1. For example, suppose 10,000 bytes are sent in 10 different TCP packets, and the first packet is lost during transmission. (Web site)

Unsigned

  1. The following pseudo-code achieves the same effect, assuming that all bytes are "unsigned" and that table L is initially zeroed. (Web site)
  2. All larger numeric data types are formed from fixed length series of bytes concatenated as described in Section 4.1 and are also unsigned. (Web site)

Encryption

  3. The result is a new hash, which means 20 new bytes for our key.

Nonce

  1. So, if we choose AES, we could use the most significant 8 bytes as a nonce, and the least significant 8 bytes as the counter. (Web site)
