okenization means randomly generating a token value for a set of plain text and storing the mapping in a database. Encryption means mathematically transforming a set of plain text into ciphertext using an algorithm and key. Tokenization is used for structured data and its application includes asset-backed tokenization on blockchain. Encryption is used for structured fields and unstructured data such as the entire file system. Another major difference is that tokenized data cannot be returned to its original form because it does not use keys to alter the original data as encryption does.
