## Introduction

Users need an ability to encrypt and decrypt column data with tenant specific keys.
Use cases include protection of sensitive column values and [GDPR] right to forget policies.
The implementation will support capabilities of the [MySQL aes_encrypt] and [MySQL aes_decrypt]
functions which encrypt and decrypt values using the [AES] (Advanced Encryption Standard)
algorithm. This functionality will enable encryption and decryption of data
accessed on remote [MySQL] servers via [MySQL Dictionary] or [MySQL Database Engine],
[MySQL Table Engine], or [MySQL Table Function].

## Terminology
