Cryptography Basics

the caesar cipher is a type of 

• monoalphabetic cipher
• polyalphabetic cipher
• bill cipher
• enigma cipher

the set of rules that you are using to encode the information

• cipher
• key
• encoding
• deciphering

to encrypt a message you need 2 main parts, a _________ & a key

• cipher
• code
• algorithm
• crypt

tells you how to arrange those rules

• cipher
• key
• encoding
• deciphering

who cracked the enigma machine

• turing
• babbage
• vigenere
• caesar

which is not a way to decode a message

• frequency analysis
• brute force
• crib usage
• slice and dice

two private keys are required in the following cipher

• caesar
• vigenere
• symmetrical
• asymetrical

In Cryptography, original message, before being transformed, is called

• Simple Text

• Plain Text

• Cipher Text

• Filled Text

_______ is the science and art of transforming messages to make them secure and immune to attacks.

• Cryptography

• Cryptoanalysis

• neither Cryptography nor Cryptoanalysis

• either Cryptography or Cryptoanalysis
