Related: pingcap/tidb#2632

Some functions that are only available in MySQL Enterprise have not yet been implemented in TiDB. However many of these are listed in the Supported functions section.

Possible solutions:

• Rename the section and add a column to list a function as supported, unsupported or deprecated.
• Remove the asymmetric encryption functions from the list of supported functions
• Implement the functions in TiDB
