That's why I've created more or less universal pigpen cipher decoder. The idea is to let you add other variants of the key and use them for deciphering. I've added the one used in Wikipedia and the one used in Assassin's Creed II. Any registered user of this site can add a new ...
; byte[] encrypted = cipher.doFinal(plaintext.getBytes("UTF-8")); String encoded = Base64.getEncoder().encodeToString(encrypted); System.out.println("Encrypted text: " + encoded); // 解密 cipher.init(Cipher.DECRYPT_MODE, secretKey, ivSpec); byte[] decoded = Base64.getDecoder()....
Double Transposition Cipher Decoder and Encoder The double columnar transposition cipher is considered one of the most secure ciphers that can be performed by hand. It is equivalent to using two columnar transposition ciphers, with same or different keys. During World War I and II, it was used ...
🔗Utf-8 decoder 🔗Utf-8 encoder Math Mathematics play an important role in logic puzzles and code-breaking. It is important to be able to convert between different number systems, and detect special properties of numbers such as that they are prime numbers. Also number sequences, like the...
