##mysql_encryption behavior for propel 2.x This behavior is written for propel 2.x and it uses mysql functions AES_ENCRYPT and AES_DECRYPT for encryption.

Instalation

composer require smolowik/propel-behavior-mysql-encryption

##How to use

First you need to define the encryption key:

Smolowik\Propel\Passphrase::createInstance("YOUR_SECRET_KEY");

Then, add the behavior to the table:

<table name="author" phpName="Author">
    <column name="id" type="integer" required="true" primaryKey="true" autoIncrement="true"/>
    <column name="first_name" type="varchar" size="50" required="true"/>
    <column name="last_name" type="varchar" size="255" required="true"/>
    <column name="email" type="varchar" size="100" required="true"/>
    <behavior name="mysql_encryption">
        <parameter name="columns" value="first_name,last_name,email" />
    </behavior>
</table>

In this part you define which columns should be encrypted. In our example, this columns: first_name, last_name and email.

<parameter name="columns" value="first_name,last_name,email" />

After building the model and update the database schema, you should be able to use encrypted columns as with any other in the table. I use this behavior to getting the list (paginate) with searching and sorting. I use it also to read and write individual rows from the database. If you want to use it in a more sophisticated way, you should thoroughly test it yourself.

##SpeedTest

Test was made on Author table with fields id, first_name, last_name and email. Fields first_name, last_name and email are encrypted. The table was 33097 lines.

With no encryption:

• insert (1000 rows) 546ms
• findByFirstName (10 rows) 37ms
• paginate (page 20 with 50 items and orderedByFirstName) 31ms

With encryption with mysql_encryption behavior

• insert (1000 rows) 584ms
• findByFirstName (10 rows) 128ms
• paginate (page 20 with 50 items and orderedByFirstName) 139ms

With encryption with uwdoem/encryption behavior

• insert (1000 rows) 577ms
• findByFirstName (10 rows) not available
• paginate (page 20 with 50 items and orderedByFirstName) not available
