## 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].
