WebJan 6, 2024 · ECB (Electronic CodeBook) mode is the simplest mode of operation of a block cipher. In ECB mode, each block of the message are simply encrypted seperately & encrypted blocks are concatenated to get cipher text. That's it. This is contrast to, say CBC mode, where each next block's encryption incorporates previously encrypted block. WebOct 3, 2024 · You can use PKCS#7 padding for ECB and CBC mode. PKCS#7 supports modes have block sizes larger than 64-bit block up to 255. The previous one, PKCS#5 padding had support up to 64-bit block size that was fine for DES. In PKCS#7 padding, the remaining bytes count is padded as a byte value. For example;

WebThe advantages of CBC over ECB are many – with ECB, assuming many things, you could manage a partial decryption and easily fill in the blanks, for example if extracting data from an encrypted hard disk. With CBC, if you are missing a few blocks in the sequence encryption becomes impossible.

In general, Crypto++ buffers can be the same or they can be distinct. I can't think of a situation where they are not allowed to be the same for in-place or in-situ processing of plain text or cipher text data.
