📝Block cipher mode of operation

tags
§ Cryptography
  • Block ciphers can be used securely to encrypt a single fixed-size block of data.
  • A mode of operation describes how to apply a block cipher to transform data large than one block.
  • Initialization Vector (IV) is an important aspect of many modes of operation.
  • Because block ciphers work on fixed-size blocks, many modes of operation require padding.
