People use ciphers to secure communication by encoding information, making it unreadable to unauthorized individuals. This enhances privacy and confidentiality, especially for sensitive data. Ciphers are also employed in various fields, including military, finance, and cybersecurity, to protect against espionage and cyber threats. Additionally, they can serve as a means of intellectual challenge or entertainment in puzzles and games.
Hebrew scholars made use of simple monoalphabetic substitution ciphers around 500 to 600 BC.
Cryptology is the study of codes and ciphers while cryptography is the creating of codes and ciphers.
Codes and ciphers have been used for thousands of years, with some of the earliest known examples dating back to ancient civilizations. The Egyptians used hieroglyphs for coded messages around 1900 BCE, while the Greeks employed simple substitution ciphers as early as 400 BCE, such as the famous Caesar cipher. Throughout history, various forms of codes and ciphers have evolved, adapting to the needs of communication and secrecy in different cultures.
Encryption and decryption algorithms are called ciphers in cryptography

Ciphers can be broadly categorized into two main types: substitution ciphers and transposition ciphers. Substitution ciphers replace elements of the plaintext with other symbols, such as the Caesar cipher, which shifts letters by a fixed number. Transposition ciphers rearrange the order of the characters in the plaintext without changing the actual characters themselves, such as the rail fence cipher. Additionally, modern ciphers often combine these techniques and incorporate complex algorithms for enhanced security.
Ciphers are used by a variety of individuals and organizations, including military and intelligence agencies for secure communications, businesses to protect sensitive data, and cryptographers researching encryption methods. Additionally, hobbyists and puzzle enthusiasts often use ciphers for recreational purposes, such as creating and solving coded messages. In the digital age, ciphers are also integral to cybersecurity, helping to secure online transactions and personal information.

To compare cryptography and cryptology we must understand that they are about coding and ciphers. To contrast them, we must understand that cryptography involves the creation of codes and ciphers while cryptology is the study of them.
