Adding JASYPT encryption to your scala JPA entity classes

October 27th, 2008

I’ve recently been looking at how best to make sensitive user data encrpytable within JPA models when in use with lift. I came accross JASYPT and it seems to be a really nice encryption tool. If you want to add it to your scala JPA models, do something like this:



package eu.getintheloop.bloglite.model

import javax.persistence._
import java.util.Date
import org.jasypt.util.password.BasicPasswordEncryptor

@Entity
@Table(){val name="users"}
class User extends BaseEntity {
  @Id
  @GeneratedValue(){val strategy = GenerationType.IDENTITY}
  @Column(){val insertable = false, val unique = true}
  var id: Long = _

  @Column{val nullable = true}
  var first_name: String = "" 

  @Column{val nullable = true}
  var last_name: String = "" 

  @Column{val unique = true, val nullable = false}
  var username: String = "" 

  @Column{val nullable = false}
  var password_hash: String = "" 

  @Column{val unique = false, val nullable = false}
  var email: String = "" 

  @Column{val unique = false, val nullable = false}
  var is_active: Boolean = false

  def password: String = this.password_hash

  def password_=(in: String) = this.password_hash = encrypt(in)

  def authenticate(in: String): Boolean = {
    new BasicPasswordEncryptor().checkPassword(in, password) 
      && is_active
  }

  private def encrypt(in: String): String = 
    new BasicPasswordEncryptor().encryptPassword(in)

}

Explictially Setting Application DocType with Lift

October 1st, 2008

As you might know, I use the lift framework a lot – I recently came across a strange issue where I couldnt set my own doctype in the layout template. Maybe this nugget of information will be usefull for someone:


ResponseInfo.docType = { 
      case _ if S.getDocType._1 => S.getDocType._2 
      case _ => Full(DocType.xhtmlStrict) 
    }

/*
Avalible options are:

xhtmlTransitional
xhtmlStrict
xhtmlFrameset
xhtml11
xhtmlMobile

*/
