## Revision History
This document is stored in an electronic form using [Git] source control management software
hosted in a [GitHub Repository].
All the updates are tracked using the [Revision History].
## 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
### AES
Advanced Encryption Standard ([AES])
### AEAD
Authenticated Encryption with Associated Data
## Requirements
### Generic
#### RQ.SRS008.AES.Functions
version: 1.0
[ClickHouse] SHALL support [AES] encryption functions to encrypt and decrypt data.
### Compatibility
#### RQ.SRS008.AES.Functions.Compatibility.MySQL
version: 1.0
[ClickHouse] SHALL support [AES] encryption functions compatible with [MySQL 5.7].
#### RQ.SRS008.AES.Functions.Compatibility.Dictionaries
version: 1.0
[ClickHouse] SHALL support encryption and decryption of data accessed on remote
[MySQL] servers using [MySQL Dictionary].
#### RQ.SRS008.AES.Functions.Compatibility.Engine.Database.MySQL
version: 1.0
[ClickHouse] SHALL support encryption and decryption of data accessed using [MySQL Database Engine],
#### RQ.SRS008.AES.Functions.Compatibility.Engine.Table.MySQL
version: 1.0
[ClickHouse] SHALL support encryption and decryption of data accessed using [MySQL Table Engine].
#### RQ.SRS008.AES.Functions.Compatibility.TableFunction.MySQL
version: 1.0
[ClickHouse] SHALL support encryption and decryption of data accessed using [MySQL Table Function].
### Different Modes
#### RQ.SRS008.AES.Functions.DifferentModes
version: 1.0
[ClickHouse] SHALL allow different modes to be supported in a single SQL statement
using explicit function parameters.
### Multiple Sources
#### RQ.SRS008.AES.Functions.DataFromMultipleSources
version: 1.0
[ClickHouse] SHALL support handling encryption and decryption of data from multiple sources
in the `SELECT` statement, including [ClickHouse] [MergeTree] table as well as [MySQL Dictionary],
[MySQL Database Engine], [MySQL Table Engine], and [MySQL Table Function]
with possibly different encryption schemes.
### Suppressing Sensitive Values
#### RQ.SRS008.AES.Functions.SuppressOutputOfSensitiveValues
version: 1.0
[ClickHouse] SHALL suppress output of [AES] `string` and `key` parameters to the system log,
