For example, once 'e' is identified, any three-letter word ending with 'e' is most likely 'the'.

Furthermore, once a common letter is known, its position in a word helps identify its partners. The idea behind this is the letter that most often occurs in a ciphertext is most likely the letter most often used in a particular language (in English it's 'e').

The 'magic' feature of Cyberchef is a life saviour.Īlthough very rarely used in CTF, a powerful tool that can be used to crack ciphers is 'frequency analysis'.Consider words like 'Flag' or the name of the competition as cribs.only using punctuation marks) can usually be googled. Less often, it can be Bacon Cipher (abbab).Ī ciphertext ending with one or two equals sign ( =) is more likely to be base64.Ī ciphertext that contains a charset of 26 26 26 different types of alphabets (usually Latin alphabets) are more likely to be one of the substitution cipher (Caesar Cipher, Vigenere Cipher, etc.) or the transposition cipher (Anagram, Rail Fence Cipher, etc.)Ī cipher with unusual charsets (e.g.

Character set used in a cipher tells a lot about a cipher, for example:Ī ciphertext with only two types of alphabets are most likely a morse code (.-.-.-.-.) or a binary code ( 0101001 0101001 0101001).

It might give you an insight on what to do

Character Set (Charset): A collection of characters that a language or cipher especially uses.

Crib: A section of known plaintext, which can be used to break a code or cipher.

Ciphertext: The opposite of plaintext, ciphertext refers to a message after it is encrypted a.k.a.

Plaintext: A message before it is encrypted and after it is decrypted a.k.a.

To understand more about classic crypto, here are some terms you need to know. Classic crypto deals with a variety of codes and ciphers, much like the ones we used to play with as children (or is it just me?) In classic crypto, we are given a piece of encrypted text and the goal is to decrypt it to get the flag. New to CTF? Have no programming experience? Classic cryptography is a great place to start.
