The earliest modes of operation, ECB, CBC, OFB, and CFB (see below for all), date back to 1981 and were specified in FIPS 81, DES Modes of Operation. In 2001, the US National Institute of Standards and Technology (NIST) revised its list of approved modes of operation by including AES as a block cipher and … See more In cryptography, a block cipher mode of operation is an algorithm that uses a block cipher to provide information security such as confidentiality or authenticity. A block cipher by itself is only suitable for the secure … See more An initialization vector (IV) or starting variable (SV) is a block of bits that is used by several modes to randomize the encryption and … See more Authenticated encryption with additional data (AEAD) modes A number of modes of operation have been designed to … See more Many more modes of operation for block ciphers have been suggested. Some have been accepted, fully described (even standardized), and are in use. Others have been found insecure, and should never be used. Still others don't categorize as confidentiality, … See more A block cipher works on units of a fixed size (known as a block size), but messages come in a variety of lengths. So some modes (namely ECB and CBC) require that the final block be padded before encryption. Several padding schemes exist. The simplest is to add See more "Error propagation" properties describe how a decryption behaves during bit errors, i.e. how error in one bit cascades to different decrypted … See more • Disk encryption • Message authentication code • Authenticated encryption • One-way compression function See more Web历史和标准化. 最早出现的工作模式，ecb，cbc，ofb和cfb可以追溯到1981年 。 2001年，nist修订了其早先发布的工作模式工作列表，加入了aes，并加入了ctr模式 。 最后，在2010年1月，nist加入了xts-aes ，而其余的可信模式并没有为nist所认证。 例如cts是一种密文窃取的模式，许多常见的密码学运行库提供了 ... WebDecrypt the input data. -a. Base64 process the data. This means that if encryption is taking place the data is base64 encoded after encryption. If decryption is set then the input data is base64 decoded before being decrypted. -base64. Same as -a. -A. If the -a option is set then base64 process the data on one line. inbound roaming means
