Cryptography

the hiding of intended meaning in communication, making communication confusing, willfully ambiguous, and harder to interpret

• hashing

• encoding

• obfuscation

• exfiltration

the same letter is used as a substitute every time

• substitution

• monoalphabetic cipher

• transposition

• shift cipher

the hiding of intended meaning in communication, making communication confusing, willfully ambiguous, and harder to interpret

• hashing

• encoding

• obfuscation

• exfiltration

decrypted or unencrypted data

• plaintext

• ciphertext

• cryptanalysis

• key

offsetting the alphabet either forward or backward by a set amount of letters

• substitution

• monoalphabetic cipher

• transposition

• shift cipher

one binary digit

• bit

• byte

• transistor

• ASCII

apply an algorithm to data input; always produces same size output

• hashing

• encoding

• obfuscation

• exfiltration

replacement of a character with a different character

• substitution

• monoalphabetic cipher

• transposition

• shift cipher

attempting to break a cryptographic system and return the encrypted message to plaintext.

• plaintext

• ciphertext

• cryptanalysis

• key

data that has been encrypted
