Described herein are various technologies related to secure generation of tokens and secure inversion of tokens. A tokenization system executes in a secure execution environment, and is configured to receive a string and an encrypted tokenization function. The tokenization system decrypts the encrypted tokenization function, and executes the tokenization function over the string to generate a token. The token is transmitted to a logically separate computing environment, and the tokenization system deletes the tokenization function and the string. | |
