Along with CBC, CTR mode is one of two block cipher modes recommended by Niels Ferguson and Bruce Schneier. CTR mode was introduced by Whitfield Diffie and Martin Hellman in 1979. CTR mode has similar characteristics to OFB, but also allows a random-access property during decryption. 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 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 … 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 … 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 hence to produce distinct ciphertexts even if … 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 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 WebJun 4, 2024 · The reviewers seem to be rejecting a proposed edit, but just to help anyone using this code, the bottom line of the top code snippet needs to be: var cipher = crypto.createCipheriv(algorithm,key,iv); where 'key' is substituted for 'password'.
