What does it mean when two encrypted files, encrypted with the same method but with different keys, when xor'd together, produce a repeating pattern?
Let's say I have fileA and fileB, both encrypted somehow, but in the same method with different keys. If I xor them together, they will make a repeating pattern of 32 bytes length. What does that ...
I'm working with documents encrypted in long term storage. When a client requests the document, the document should be delivered encrypted under a distinct key (distinct from the long term storage ...
Can we replace the XOR operation in the DES algorithm with some other operation? If so, does it work for both encryption and decryption?
I am aware of the vulnerabilities of simple xor ciphers and recently I came across a block cipher that claims to solve those vulnerabilities. The cipher goes as follows with both the block and key ...
