Caesar cipher
This term refers to one of the simplest and most widely known encryption techniques. It is primarily used today as an introductory example in cryptography and computer science education rather than for actual security, as it is trivial to break via frequency analysis or brute force.
In a technical context, the term is often used interchangeably with "shift cipher," although a Caesar cipher specifically refers to a shift cipher where the shift value is fixed. It carries a historical connotation, evoking the era of ancient Roman military communications.
