This example uses a weak algorithm: PBEWithMD5AndDES
This example should be updated to use a stronger alg (ex: PBEWithHmacSHA256AndAES_256) that was added in JDK 8 as part of JEP 121.

There is also a similar example in the Managing Algorithm Parameters section for Cipher in the JCA guide: http://docs.oracle.com/javase/8/docs/technotes/guides/security/crypto/CryptoSpec.html#Cipher
