What is encryption methods?

Encryption methods are techniques used to transform data into an unreadable format, called ciphertext, to protect its confidentiality. Common methods include symmetric-key algorithms (like AES) where the same key is used for encryption and decryption, and asymmetric-key algorithms (like RSA) where separate keys are used for encryption and decryption. Hashing algorithms (like SHA-256) are also used to create a one-way function of data, used for integrity checks and password storage. Encryption is essential for securing data at rest and in transit, protecting sensitive information from unauthorized access.
