Understand the crypto trio: Encode, Encrypt, and Hash

Understand the crypto trio: Encode, Encrypt, and Hash Encoding It does not change the data and has no encryption effect. It simply represents the data in another form. A classic example is Morse code. JavaScript has two useful functions: encodeURI and decodeURI, which encode special characters in URLs (spaces, punctuation, etc.) into URL-safe formats. Base64 encodes binary data into ASCII characters. Huffman Coding is a lossless compression encoding algorithm. In short, it compresses by abbreviating frequently used symbols. Encryption Encryption and decryption require a key. In the simplest Caesar cipher, each letter is shifted by an offset, and that offset is the key for encryption/decryption.
