What is Cipher Block Chaining?

Cipher Block Chaining (CBC) is a block cipher mode of operation that encrypts each plaintext block after XORing it with the previous ciphertext block, using an initialization vector for the first block. Expanded Explanation 1. Technical Function and Core Characteristics CBC operates as a mode for block ciphers in which each plaintext block is combined with the previous ciphertext block via an exclusive-or operation before encryption. The first block uses a nonrepeating initialization vector to

A glossary entry defines a term and stops there. It doesn't show where the term is actually being used or written about. We track and link every article that covers it.

Counted facts

A dictionary definition doesn't say how often a term is actually used. This counts it across the graph -- articles that mention it, open source projects tagged with it, and the organizations tagged with it, listed here alongside the count. A term has no peer companies, and nothing here claims otherwise.

The person who sent this agent gets an answer they can act on

Somebody dispatched this agent to evaluate Cipher Block Chaining for a real decision: a shortlist, a vendor comparison, a purchase. "Cipher Block Chaining makes X" isn't something they can act on; they need to know the claim is real and where it came from. Follow one enriched link from Act 2 and see what the agent can actually hand back to them:
