In LEPTON 4.1.0 we introduce functions/methods to encrypt and decrypt the data in table_fields of the database.
In addition to methods
there are some new methods to save encrypted data into your database and read decrypted data from your database:
All you have to do is to write the table_fields you want to be encrypted in an array and pass it as an parameter with the method.
Details can be seen in the documentation: lepton_secure_database.
Please keep in mind that you need openssl enabled in your php-release (standard from PHP 7.2x). Please also take care that the fields to encrypt have a length of varchar = 128 to fit with the encrypted values.
