Security code - need some help with key unwrapping

[JPractitioner]

Hi all,

i need to unwrap a key(keyX), using another key (keyY)

keyY is stored in a HSM simulator

i reach to keyY by doing the following
..
..
..
KeyStore keyStore = KeyStore.getInstance("CRYPTOKI", provider.getName
());
keyStore.load(null, password.toCharArray());
Key keyY = keyStore.getKey("myKeyY", null);

now suppose keyX = "F81CF8A4A81962C1"


i manage to do the unwraping code like the followings...

String keyX = "F81CF8A4A81962C1";
byte[] b = keyX.getBytes();

WrappingKeyStore wrapKeyStore = WrappingKeyStore.getInstance
("CRYPTOKI", provider.getName());
Key uk = wrapKeyStore.unwrapKey(k,transformation,b,"DESede");

but i get this error

CryptokiError: 0x13 attribute value invalid

any idea?

TIA

Plugins are notorious. Nothing is documented. It is never clear what
is optional.

x13 is a Cr. Try trimming and Strings before you feed them into your
black box.

If that does not work, look at the stack trace to find the code that
was checking something at the time it threw the exception. As least
you might figure out which parm it was complaining about.

Sun could save so much frustration with a little cook book essay
showing you how to USE JCE to accomplish each of the standard things
you might do with each of the methods.

x13 is a Cr.

x13 is not a CR, it is ASCII 19(10), which is DC3, which in this
instance is some sort of error code.

i see..
thanks to the both of you, I just realized the exception was thrown by
the third party library. I shouldn't be asking here but the points you
guys gave do make sense, thanks ya

oops. decimal 13 hex 0D is CR. 10 hex 0A is LF.
