It's sort of a Caesar shift, only the key is more than one letter, and it's repeated, so the cipher will be harder to break. What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? Video. Tool to encode and decode simple ciphers. If the plaintext is found it is encrypted into the path_to_ciphertext folder. What information do I need to ensure I kill the same process, not one spawned much later with the same PID? For example, in the row of the key is "B" and the ciphertext is "K" and this ciphertext letter appears in the column "J", that means the first plaintext letter is "J". I tested this code with your test case and a couple others: It returns the same results as your code for the first case and your test case. You need at least JDK 11 (OpenJDK is recommended).

A tag already exists with the provided branch name. int current = (int) sb.charAt(keyspace - (i + 1)); int current = (int) sb.charAt(keyspace - 1). You check to see if j+l > 26, and shift if needed, but you should be checking whether j+l > 25. The key will be written both on the standard output and a file named key_path_to_plaintext (notice the prefix). Decryption:Decryption is performed by going to the row in the table corresponding to the key, finding the position of the ciphertext letter in this row, and then using the columns label as the plaintext. You signed in with another tab or window. The purpose of this code seems to be to fill in the section of of the square corresponding to the letters in the alphabet.
