What is cipher in Java?
The Java Cipher ( javax.crypto.Cipher) class represents an encryption algorithm. The term Cipher is a standard term for an encryption algorithm in the world of cryptography. You can use a Cipher instance to encrypt and decrypt data in Java. Read more about Cipher class in JavaDoc.
What is route cipher?
The Route Cipher is a transposition cipher. It rearranges the plaintext letters based on a shape of an imaginary path drawn on a grid, which contains all the message letters. For more detailed description of the Route Cipher, please visit Crypto-IT webpage. Choose a secret key value.
How to solve route transposition ciphers?
This tool helps you solve route transposition ciphers. Just enter your text and experiment with the column length and transposition type to search for solutions for your cipher. To help you further, this tool also suggests probable column lengths. These lengths are calculated such that the resulting text will completely fill a rectangle.
