How to search a MySQL database with encrypted fields

Question

I have 4 columns in the table. I stored in encrypted values to encryptemployeesId . Thousands of records is available. I want to display particular record using only employeesId . Kindly help us.

1. id int
2. encryptemployeesId varchar
3. secret_Key varchar
4. salary varchar

Note: The encrypteemployeesId is Dynamic .

Answer 1

If you have table which stores encrypted ID of the employee then you need the same encrypting algorithm for searching the database. EX::

1) Encrypting Algorithm encrypts your employee ID each time new entry is made in database.

2) Use the Encrypting algorithm in search_employee_by_id() method as:

function search_employee_by_id(int id) {
response = encrypt_algorithm(id); //encrypts emplyoeeid you want to search say 5
query.execute("SELECT * FROM EMPLOYEE where encrypted_id =:encryptemployeesId"); //employee id 5(encrypted) matches any employee with id 5.
    }

Hope this helps
