WebMar 14, 2024 · 1. Reversible or Irreversible Encryption is a two-way function where data is passed in as plaintext and comes out as ciphertext, which is unreadable. Since encryption is two-way, the data can be decrypted so it is readable again. The cryptographic hash function is a non-reversibility or one-way function.

WebOct 30, 2024 · To begin with, I know that encryption is a two-way process that can be reverted. And hashing is a one-way process that is irreversible. That last point just doesn't make sense to me, if I use an algorithm to hash "hello", wouldn't the same algorithm, but "reversed" (meaning, it works "backwards"), be able to convert that hash to "hello" again.

WebJun 24, 2024 · A block cipher does just this, except the permutation is not fixed. Rather, it is "chosen" by the key. Each key selects a different permutation from all possible permutations. Additionally, there are far more than four elements. AES encryption permutes a set of $2^{128}$ different elements, chosen by the key. Decryption simply gives you the ...
