Creating a routine

In this procedure, create a custom routine to execute the algorithm for password encryption.

Procedure

In the Repository tree view of your Talend Studio, expand the Code node, right-click Routines and select Create routine from the contextual menu to create a new routine named MyRoutine.

In the new routine that opened in the routine editor, add a function named decrypt and define the specify mechanism to decrypt the encryption string of the password.

The code of the function reads as follows:

public class MyRoutine {
    public static String decrypt(String encryptedPassword) {
        StringBuffer output = new StringBuffer();
        for (int i = 0; i < encryptedPassword.length(); i++) {
            char c = encryptedPassword.charAt(i);
            if (c >= 'a' && c <= 'm')
                c += 13;
            else if (c >= 'A' && c <= 'M')
                c += 13;
            else if (c >= 'n' && c <= 'z')
                c -= 13;
            else if (c >= 'N' && c <= 'Z')
                c -= 13;
            output.append(c);
        }
        return output.toString();
    }
}

When done, click Ctrl+S to save your routine.
