WebOct 21, 2024 · This challenge asks us to detect whether we’ve encrypted a text with ECB or CBC, chosen at random. Recall the properties of ECB vs CBC — ECB will take two identical plaintext blocks and produce two identical ciphertext blocks. So just detect ECB using the function in challenge 8. If it's ECB, return ECB. If not, return CBC 2.12. WebI am uploading my solutions to cryptopals crypto challenges.
