Hash functions generate a fixed-length message digest or summary from a message of any size, and it is primarily used to ensure the integrity and authenticity of the message. It creates a unique digital fingerprint, making it particularly useful in verifying that a message has not been tampered with or altered in transit. Maps are data structures used to store key-value pairs, whereas keys are used to unlock the content of encrypted messages. While encryption is used to scramble and hide the content of a message, hash functions generate a summary or hash of the message content.
