[Cryptix-users] Cryptix JCE and OpenPGP w/ Java 1.4.x

[Tim B. <tba...@av...>]

I have read able the issue with JCE 1.2.1 and signed providers but I've
noticed that if I delete the jce.jar file from $java.home/jre/lib then I can
get the examples to work.  Is there a better way to do this and if not is
Cryptix planning on release a JCE implementation that works with Java 1.4.x
in the near future?

Thanks,
Tim Bardzil

Roger,

No, I am sorry, I am using the Cryptix JCE classes.

Faveh,

On which line does the exception occur?

FW: [Cryptix-users] Automatic padding doesn't seem to work for Rijndael (in plain text)

[<nbr...@to...>]

Hi,

I'm using this stuff for the first time, but am bemused by the
following:

The javadoc for xjava.security.Cipher states that all versions of
crypt() automatically pad/unpad as necessary. =20

But a simple test case for Rijndael:

      String message =3D "Dennis eats worms.";
      Cipher cipher =3D Cipher.getInstance(algorithm);
      cipher.initEncrypt(new RawSecretKey(algorithm, key));=20
      byte[] encryptedMessage =3D cipher.crypt(message.getBytes());
      cipher.initDecrypt(new RawSecretKey(algorithm, key));
      byte[] unencryptedMessage =3D cipher.crypt(encryptedMessage);
      System.out.println("message=3D" + new String(unencryptedMessage));=


Throws the following exception:

Exception in thread "main" xjava.security.IllegalBlockSizeException:
Rijndael: Non-padding cipher in ENCRYPT state with an incomplete final
block
        at xjava.security.Cipher.updateInternal(Cipher.java:1264)
        at xjava.security.Cipher.crypt(Cipher.java:1046)
        at xjava.security.Cipher.crypt(Cipher.java:1011)
        at com.touchcorp.test.Encrypt.main(Encrypt.java:46)

Either the javadoc or the code appears to be wrong.

Help?

RE: [Cryptix-users] Cryptix and Mac OS X

[Roger W. <ro...@pr...>]

Are you using Cryptix 3.2.0?

The problem we had was when using the addProvider method to install the cryptix libraries:

"Netscape security model is no longer supported.
Please migrate to the Java 2 security model instead."

Then everything just bombs out... im guessing that this is b/c of the calls that cryptix makes to netscape.security.  We are using
the following line to add the libraries:

java.security.Security.addProvider(new cryptix.provider.Cryptix());

are you also using this method in your s/w?

Thanks,
Roger.

I'm personally using them on OS X. I don't remember but may very well
have tweaked something to make it work. What exception are you seeing?
