Ciphers

Ciphers are methods used to convert information into a form that is unreadable to anyone without a special key. They are essential for securing communication, ensuring privacy, and protecting sensitive data. Using algorithms, ciphers scramble the original message (plaintext) into an encoded version (ciphertext). Only someone with the correct key can invert the process and access the original message. Ciphers are fundamental to modern cybersecurity, underpinning everything from online banking to private messaging, by maintaining confidentiality and integrity of information in transit and at rest.
