MySQL Enterprise Encryption is an extension included in MySQL Enterprise Edition, a commercial product. To learn more about commercial products, http://www.mysql.com/products/.
As of MySQL 5.7.9, MySQL Enterprise Edition includes a set of encryption functions based on the OpenSSL library that expose OpenSSL capabilities at the SQL level. These functions enable Enterprise applications to perform the following operations:
Implement added data protection using public-key asymmetric cryptography
Create public and private keys and digital signatures
Perform asymmetric encryption and decryption
Use cryptographic hashing for digital signing and data verification and validation
Enterprise Encryption supports the RSA, DSA, and DH cryptographic algorithms.
Enterprise Encryption is supplied as a user-defined function (UDF) library, from which individual functions can be installed individually.
