MySQL encryption library similar to SQLCipher

I'm working on encrypting some database fields. By encrypting of course I lose some search functionality. I found this library called SQLCipher which handles the encryption at the data开发者_JS百科base level, but it's for SQLite. Is there something similar for MySQL?
