Description:
MySQL could be a lot more usable in commercial environments if there was the possibility to have DB content encrypted by Table or by Column.

I am aware that this is certainly not an easy topic (see also http://lists.mysql.com/mysql/101724) I can expect to be solved in the short time, but if I could say that MySQL DBMS can do that, it certainly is a very good selling argument when proponing to choose MySQL for a professional project even if those features are not used in the beginning and perhaps never since the design minimized the need to store sensitive data altoghether or due to performance reasons...

For the related topic of password security on the windows mysql version, see http://bugs.mysql.com/bug.php?id=784.

oops, column encryption is probably handled by http://www.mysql.com/doc/en/Miscellaneous_functions.html such as AES_ENCRYPT, but table encryption still remains needed!

Also, some hints, how to protect the keys outside mysql would be useful in page Miscellaneous_functions.html

Thank you for the reasonable feature request.

Right now you can use VIEW + TRIGGERS + STORED PROCEDURES to realize table encryption functionality.

You can use commercial softwares for the same purpose e.g. http://solutions.mysql.com/solutions/item.php?id=431

In MySQL 5.7 there is tablespace encryption.
https://dev.mysql.com/doc/refman/5.7/en/innodb-tablespace-encryption.html

MySQL also has AES_ENCRYPT() and AES_DECRYPT() which can be used as column encryption.
https://dev.mysql.com/doc/refman/5.7/en/encryption-functions.html

MySQL Enterprise has additional encryption capabilities:
