WebMar 14, 2024 · CBC stands for 'Cipher block chaining' and it's a mode of operation for AES. There are Wikipedia articles for CBC and AES here and here. Back to our code. After we initialise the encryption algorithm we create a StringSource (line 17) and pass our input for its first parameter (line 18). WebA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. fnd clinic boston

So in that respect it is no worse than GCM. You can also achieve limited parallelization for encryption with CBC by randomizing the block in the middle of your message and then compute blocks from that point forward and backwards in parallel on two threads. fndc ltccp 2004
