Cipher — A cipher is an algorithm for transforming plaintext into ciphertext and reversing that transformation with appropriate key material. Its security depends on its design and correct use. Strong ciphers still require suitable configurations, protected keys, and reliable implementations. – Cryptography

Cipher — A cipher is an algorithm that transforms readable information into an encrypted form and supports its recovery through decryption. Its operation typically depends on a cryptographic key. Different cipher designs address different requirements for protecting stored or transmitted information.
