WebNov 14, 2024 · Feedback. A cipher suite is a set of cryptographic algorithms. The schannel SSP implementation of the TLS/SSL protocols use algorithms from a cipher suite to create keys and encrypt information. A cipher suite specifies one algorithm for each of the following tasks: Key exchange. Bulk encryption. WebOct 22, 2024 · $\begingroup$ In step 3 I'm encrypting 2 blocks of plain-text (P1 P2) so it is not 16-byte but indeed 32-byte plaintext and it results in cipher text which is 48 byte. The first 32 byte is the cipher text (C1 C2) and the last 16 byte padding. I hope that makes sense! But what do you think about the second question?

To encrypt a series of plaintext blocks p 1;p 2;:::p n using a block cipher E operating in cipher block chaining (CBC) mode, each ciphertext block c 1;c 2;:::c n is computed as c i= E k(p i c i 1), where c 0 is a public initializa- tion vector (IV) which should be di erent for each encryption session.
