encryption example

[Björn-Peter Tietjens]

Hi,

i keep getting the exception:
13:34:52,400 ERROR Encrypter:178 - 
org.apache.xml.security.encryption.XMLEncryptionException: Invalid key 
length: 16 bytes(Invalid key length: 16 bytes)


i used the encryption sample to encrypt some xml doc when executing this 
on the tomcat webapp it keeps telling me that the key has an invalid 
length... but it generated the key itself as in the example.

Thanx for some hint.
Cheers Björn
