WebApr 9, 2024 · The cipher text is not in a format. It is just an unstructured series of pseudorandom bytes. You just need to convert a series of bytes to a Hex string. (There's nothing special about this being encrypted; it's just bytes.) I've marked a specific example, but there are many here. – WebThe message from the sender is first scrambled using RSA algorithm and the cipher text is cloaked within an image. The correct stego-image is shared with the receiver only if he answers the previously shared (only between sender and receiver; undisclosed to others) question correctly. The receiver first gleans the cipher text from the stego ...

If the first block were not secure with a known IV, the second block would not be secure with known ciphertext, and ciphertext is known. So if the second block is secure, the IV need not be kept secret. – David Schwartz great gatsby ch 2

"WebBlock cipher algorithms encrypt data in block units, rather than a single byte at a time. The most common block size is 8 bytes. Because each block is heavily processed, block ciphers provide a higher level of security than stream ciphers. However, block cipher algorithms tend to execute more slowly than stream ciphers.
