A method of encoding information so that it can only be accessed by authorized parties. Also known as the Masonic Cipher, it is a substitution cipher used in cryptography that replaces letters with symbols and shapes.
A cipher that replaces each letter in the plaintext with a different letter, symbol, or number in the ciphertext. A graphical representation used to represent something else, such as a letter or number in a cipher.
The process of converting plaintext into ciphertext using a cryptographic algorithm and a key. The practice of securing communication from unauthorized access.
A sequence of steps or instructions used to solve a problem or perform a task. The process of converting ciphertext back into plaintext using a cryptographic algorithm and a key.

The encrypted message or data that is the result of an encryption process. The original message or data that is to be encrypted.
The set of symbols used in a cipher to represent plaintext letters. A secret value used to encrypt or decrypt information.
A substitution cipher in which each letter is replaced with a single, fixed symbol throughout the ciphertext. The practice of using the same key repeatedly in a cipher.
The length of the key used in a cipher, typically measured in bits. A substitution cipher in which the symbol used to replace a letter varies depending on its position in the plaintext.

 

Cryptanalysis

 

The process of analyzing encrypted information to decipher the original message or data.
