There are many different techniques that you can use to crack an encryption. Here we have one of them and a list of useful books that you can pick up to learn more.

Encrypt the new pair, re-pair the remining letters and continue. If the letters appear on the same row of your table, replace them with the letters to their immediate right respectively, wrapping around to the …

To encrypt a plaintext message using the Vigenère Cipher, one locates the row with the first letter to be encrypted, and the column with the first letter of the keyword.

To encrypt a plaintext message using the Vigenère Cipher, one locates the row with the first letter to be encrypted, and the column with the first letter of the keyword. The ciphertext letter is located at the …

The Keyword cipher is a substitution cipher that uses an alphabet that can be represented with a keyword.

With over 15,000 brain teasers, riddles, logic problems and mind puzzles submitted and ranked by users like you, Braingle has the largest collection anywhere on the internet.

A Caesar Cipher is one of the most simple and easily cracked encryption methods. It is a Substitution Cipher that involves replacing each letter of the secret message with a different letter of the alphabet …

To decipher a Bifid encrypted message, you first convert each letter into its corresponding number via the Polybius Square. Now, divide the long string of numbers into two equal rows.

To make the message even more difficult to decipher, you can take the ciphertext produced by this algorithm and run it through the encryption again using a different keyword.

A one-time pad should be used only once (hence the name) and then destroyed. This is the first and only encryption algorithm that has been proven to be unbreakable. To encipher a message, you take …
