Hello,

i am trying to decrypt a file i had encrypt before. Encryption works
fine, but every time i am trying to decrypt, i get the following error:


java.security.UnrecoverableKeyException: extra data given to DerValue
constructor
  at sun.security.provider.KeyProtextor.recover(KeyProtector.java:311)
  at
sun.security.provider.JavaKeyStore.engineGetKey(JavaKeyStore.java:103)
  at java.security.KeyStore.getKey(KeyStore.java:289)

Then it directs to my own code, to the line: key =
ks.getKey("MyKeyAlias",mypassword);

Thank you in advance for every hint,

Susi
