Is there a way to encrypt the whole data of a mysql DB using the AES 256 symmetric encryption method without encrypting the data manually using AES_ENCRYPT ?

This article explains about the same functionality in MsSql databases

    Encrypt the hard drive? – Michael Hampton Apr 28 '14 at 14:22
  • Hmm... I prefer encrypting the data of the db and not the whole HD if it's possible – Yaron U. Apr 28 '14 at 15:57

    You could store the MySQL database on a separate partition and encrypt only that partition. – Cristian Ciupitu Apr 29 '14 at 0:07
  • Correct me if I'm wrong - but, encrypting the partition itself helps only if someone tries to read the data without being already logged to the OS.. right? – Yaron U. Apr 29 '14 at 11:51
  • What language are you using? – Markus W Mahlberg May 13 '15 at 11:31

MySQL doesn't support data file encryption natively, but there are ways to do it. There is a product called Vormetric Transparent Encryption. Read info about it here: http://www.vormetric.com/data-security-solutions/use-cases/database-encryption But if you want to actually use SQL for this purpose, newer versions support AES_ENCRYPT() and AES_DECRYPT() (the official AES standard). You can read about the two functions here, in the mysql 5.x manual: https://dev.mysql.com/doc/refman/5.1/en/encryption-functions.html#function_aes-encrypt

So basically you can encrypt the data prior to the insert query. MySql wont know the difference. also, you will have to decrypt it when extracting any data.

  • sounds interesting. is it possible for live db and not only for backups? – Yaron U. Apr 29 '14 at 20:12
  • I think you are looking for filesystem encryption. – da_didi May 1 '14 at 6:50
  • I just found this presentation, pls read slide 53 and following: yassl.com/files/yassl_securing_mysql.pdf – da_didi May 1 '14 at 7:22
