What type of mysql matches []byte?

Question

MySQL

Hello. I encrypt login and email using xxtea. At the output, I have data in the []byte format. Now I can convert []byte to string and store it in a regular text field. But then I need to convert this string back to []byte. Someone will say that saving on matches. And if I have a couple of million requests to the database, then this savings will give me another trailer of matches for sale :)
Thanks in advance for your help.
