Could someone please give a walkthrough of how this works: Decrypting a vigenere cipher with a reused one-time pad.
It was never fully answered with the example given in the comment.
Plaintext 1 - apples
Plaintext 2 - orange
Key : fruits
They are all 6 letters. If 'fruits' was used to encrypt both 'apples' and 'oranges' using vigenere, how could an attacker obtain the plaintexts and key with only knowing the ciphertexts?
