Vigenère cipher, aka “le chiffrage indéchiffrable”

Vigenère cipher

Using Vigenère cipher each letter in a text is replaced by a letter a number of places down the alphabet reliant on a key.

Rail fence – the simplest transposition cipher

Rail fence cipher

Rail fence cipher lays out characters in a zigzag pattern across a number of “rails” and reads them off row by row.

Letter number cipher

Letter number cipher (A1Z26) replaces each letter by the corresponding position in an alphabet (A=1, B=2, …, Z=26).

Polybius Square – A device used by the ancient Greeks

Polybius square

Polybius square is a method in which a chosen alphabet is layed out in a grid that is then being used to represent each letter by its coordinates.

Where do 6-digit 2FA codes come from?

TOTP 2FA codes

Many online services offer two-factor authentication (2FA) to secure accounts with an additional time-based one-time password (TOTP) changing every 30 seconds.

Cryptographic hash function

Hash function

A hash function maps data of arbitrary size to hash values, hash codes, digests, or simply hashes of fixed size.

Hash-based message authentication code (HMAC)

HMAC

Method using a cryptographic hash function and a secret cryptographic key to verify both integrity and authenticity of a message.

Translate text to binary

Text encoder

Text encodings are used to digitally represent text in binary on computers and other devices.

Measure data predictability with Shannon Entropy

Entropy

Entropy measures the rate at which information is produced by a source of data. It can be used to detect whether data is likely to be structured or unstructured.
