This worked for me. Thanks a ton.

 DES is a block cipher so it needs
 padding if the plain text isn't an exact multiple of the block size.
 Apparently Sun has a default padding scheme, but IcedTea doesn't. As
 a workaround you can explicitly specify a padding:

 Cipher ecipher = Cipher.getInstance("DES/ECB/PKCS5Padding");

 According to https://www.herongyang.com/crypto
 /des_java_jce_sun_implementation_3.html this is the same as what
 "DES" gives you on the SunJCE.
