WebNov 15, 2006 · The Crypto++ library includes benchmarking capabilities through the test harness using the 'cryptest b' command line. In addition, the benchmark can take arguments such as bounding time for each test and the CPU speed. See usage.dat for details or run 'cryptest' with no arguments. 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.

WebHere’s an example (using the key “ECB”): You actually can. You actually can do even more: encrypt a file format into an other. You need to play with key and IV to get that the message input is "well" transformed by the encryption. If you control the key and the IV and the initial and final file you ave enough freedom to achieve your aim.
