Az egyszerű analógiák jól jöhetnek, ha gyorsan kell érthetővé tenni bonyolultabb fogalmakat. Íme:
Encoding is a way of translating between different formats. Like converting a Spanish recipe for cake into English.
Encoding data is typically used to ensure integrity and usability of data and is commonly used when data cannot be transferred in its current format between systems or applications.
Pl.: LZW, HEVC, ASCII, UTF-8, base64.
Encryption is a way of protecting data behind a secret. Like sealing a box of chocolate in a locked safe so your kids don’t find it.
Encryption is the process of securely encoding data in such a way that only authorized users with a key or password can decrypt the data to reveal the original. There are two basic types of encryption; symmetric key and public key.
Pl.: RSA, GPG.
Hashing is a way of permanently converting from one recognizable thing to something uniform and simple. Like grinding a cow into a hamburger.
Hashing involves computing a fixed-length mathematical summary of data, the input data can be any size. In contrast to encoding, hashing cannot be reversed.
Pl.: CRC, MD5, BLAKE, SHA.
