Janos,

I'm not sure which version of the JCE you are using but the second =20
error you mention (JDK 1.4) should have been fixed with the latest JCE =20=

release. Get it from the website at http://www.cryptix.org .

[Cryptix-users] Using getEncoded() on Keys

[James A. <jd...@ks...>]

I'm trying to do some public/private key encryption, however I'm coming 
across a problem.  I need to get the byte[] that .getEncoded() returns. 
 I am using an example that is slightly modified from the Examples 
provided by Cryptix.

<pre>
   public static void createKeys() throws Exception{
      algo = "RSA";
      KEY_SIZE = 1024;
      KeyPairGenerator kpg = 
KeyPairGenerator.getInstance(algo,"CryptixCrypto");
      kpg.initialize(KEY_SIZE);
      KeyPair kp = kpg.generateKeyPair();                 
System.out.println("The Keys: ");
      RSAPrivateKey prk = (RSAPrivateKey)kp.getPrivate(); 
System.out.println(new String(prk.getEncoded()));  // !--Error here
      RSAPublicKey puk = (RSAPublicKey)kp.getPublic();    
System.out.println(new String(puk.getEncoded()));
      algo = algo + "/ECB/PKCS#1";
      c = Cipher.getInstance(algo,"CryptixCrypto");
      d = Cipher.getInstance(algo,"CryptixCrypto");
      c.init(1, puk);
      d.init(2, prk);
}
</pre>

When I try to using the getEncoded method, i get this error:
<pre>
Exception in thread "main" java.lang.RuntimeException: NYI
        at java.lang.Throwable.fillInStackTrace(Native Method)
        at java.lang.Throwable.fillInStackTrace(Compiled Code)
        at java.lang.Throwable.<init>(Compiled Code)

        at PKI.createKeys(PKI.java:47)
        at PKI.main(PKI.java:25)
</pre>

I've been told that the error "NYI" means not yet implemented.  Am I 
doing something wrong? or is the JCE incomplete?  

If I take out the "System.out.println(new String(prk.getEncoded()));" 
the program works fine.  Any help?

[Cryptix-users] Problem with the new Snap and Java 1.4.1

[Alsbih, A. <al...@mi...>]

Hi

I have used the old Snaps with Java 1.3 without any problems

Now I would use the new Snap "cryptix-jce-20030102-snap" with
"cryptix-openpgp-20020719-snap" with Java 1.4.1 but I get an error when
I try to run any program.

I have used the Encrypt example with a key that was created by gnupg
1.2.1 in asc. Format.
The compilation works without any error but if I want to run it I get :

Hmm. There is no such thing as a 'String representation' of keys. 
Symmetric keys are strings of bits (usually multiples of 8 though) and 
asymmetric keys tend to be tuples of a few large integers. There exists 
no single universal String representation and therefore appropriate 
conversion methods cannot be provided.

That said, you can usually write a a key dump routine quite easily. For 
example, if you are dealing with an RSAPrivateKey, you can obtain the 
BigIntegers and call toString on those.

Another approach is to call the (broken API design alert!) getEncoded 
method which is provided in every key. This results in a byte[] which 
is easily converted to, say, a hex string. The contents of the byte[] 
are -yuck- implementation dependent and -of course- there is no way to 
support multiple different encoding schemes of a single key with this 
interface.

HTH,

[Rudy V. <rud...@su...>]

Hi,

I passed "hours" to find why SignedMessage.verify always give me the 
following

Exception in thread "main" java.lang.IllegalStateException: This is not 
a secret key
        at cryptix.openpgp.algorithm.PGPDSA.initSign(PGPDSA.java:367)

        at cryptix.openpgp.examples.MyClearSign.main(MyClearSign.java:266)

Nothing did !

I tried to use the 2 following calls

either a KeyBundle
or a pubkey

abstract  boolean verify(KeyBundle pubkey)
          Verify if this message was correctly signed by a particular 
keybundle.

abstract  boolean verify(java.security.PublicKey pubkey)
          Verify if this message was correctly signed by a particular 
public key.

the 2 calls gave the same error...................

You can find "attached" the code I used (from ClearSign).

What I can tell you

cryptix.openpgp.provider.PGPSignedMessageImpl.verify calls 
cryptix.openpgp.algorithm.PGPDSA.initSign
and
in PGPDSA.initSign



public void initSign(int hashID, PGPAlgorithmFactory factory) {
        try {
            if (! (factory.getHashAlgorithmString(hashID).equals("SHA-1")
                || factory.getHashAlgorithmString(hashID).equals("SHA1")))
            {
                // ### FIXME
                throw new IllegalArgumentException("Only SHA-1 is 
supported for " +
                                           "signatures by DSA keys.");
            }
            if(x == null) {
                throw new IllegalStateException("This is not a secret key");
            }
            sig.initSign(new PGPDSAPrivateKey());
        } catch (InvalidKeyException ike) {
            throw new IllegalStateException("InvalidKeyException");
        }
    }
   

x is null, thus not initialised and I don't understand why...

Unfortunately that is true. Blame Sun and the US government.

There are three solutions:

1. Go back to JDK 1.3 (you are probably using JDK 1.4 now).
2. Remove Sun's JCE (usually that just means removing one jar file).
3. Use the new snapshot uploaded by Jeroen (preferred, especially for new 
applications as cryptix 3.x will not be maintained for a long time any 
more).

It has been a while since I looked into it, but if I remember correctly 
this isn't possible.

Signing of course is not the problem, but getting cryptix 3.x to work in a 
JCE 1.2 environment is. The only way to make it work is to remove Sun's 
JCE, which also removes the need for a signed provider.

[Cryptix-users] Java SecurityException: Cryptix may not be signed by a trusted party

[David L. <Dav...@ap...>]

I've tried loading Cryptix JCE v1.2 & Cryptix 3 dynamically as documented.

provider cp = new Cryptix();    //  new CryptixCrypto in JCE v1.2
Security.addProvider(cp);
cp.list(System.out);

So far so good.  Now creation of any Cipher e.g...
Cipher cpp = Cipher.getInstance("Blowfish","Cryptix");
leads to...

java.lang.securityException: The provider xxx may not be signed by a 
trusted party

As far as I can make out from the forum at javasoft this is because the jar 
is not signed.

Q. Is that really true?
Q. If not, any idea what the problem might be?

P.S. I'm using the NetBeans IDE

[Cryptix-users] Can the OpnPGP library be used without the JCE?

[James M. <ja...@sp...>]

Hi folks, I was wondering if it's possible to use the cryptix openpgp 
implementation without registering it as a jce provider? I'd like to 
use it in an applet and the security restrictions around adding 
providers makes this difficult. Any ideas?

-James

[Cryptix-users] Problem with the Libraries and Java 1.4.1

[Alsbih, A. <al...@mi...>]

Ladies and Gentlemen, unfortunately I have a problem with the cryptix =
libraries!=20
We are not able to compile your examples, with the libraries you =
provide.=20
We try to import keys from PGP and GnuPGP since two weeks, but this =
neither works with keys in the RSA -  RSA Legacy nor DH format.

The program breaks always off at :
EncryptedMessageBuilder emb =3D =
EncryptedMessageBuilder.getInstance("OpenPGP");

With the following error :
java.lang.RuntimeException: RSA algorithm not found. Provider problem?
	at cryptix.openpgp.algorithm.PGPRSA.encrypt(PGPRSA.java:521)
	at =
cryptix.openpgp.packet.PGPPublicKeyEncryptedSessionKeyPacket.encrypt(PGPP=
ublicKeyEncryptedSessionKeyPacket.java:153)
	at =
cryptix.openpgp.provider.PGPEncryptedMessageBuilder.engineBuild(PGPEncryp=
tedMessageBuilder.java:221)
	at =
cryptix.message.EncryptedMessageBuilder.build(EncryptedMessageBuilder.jav=
a:253)
	at pgpver.verschluesseln.main(verschluesseln.java:116)

is this problem well-known by you?
We have used Java 1.4.1.

On the 2nd problem, I think it may be related to compression?

I can decrypt short strings (i.e., 100 characters of text) but when it
gets longer, I think PGP automatically compresses it.  I tried to get
the classname of the message object and it is NOT a compressed stream so
I'm thinking it doesn't know that it's a compressed stream.

For your first problem I have a Solution!
- write your message to an file
- open a FileInputStream to this file
- try to decrypt the File but !!!! BUT DO NOT CLOSE THE INPUTSTREAM !!!
This works fine for me

For the second problem i have the same and need also help!

PLEASE

I am having the same problem that was mentioned on 11/19 by Krishna
Arji. 

When I encrypt a file using PGP 6.5.8 and then try to decrypt it using
OpenPGP, I get the following runtime exception:

Exception in thread "main" java.lang.RuntimeException: IOException on
ByteArrayInputStream, should not happen. java.io.EOFException:

cryptix.openpgp.provider.PGPEncryptedMessageImpl.decrypt(PGPEncryptedMes
sageImpl.java:301)
        at Decrypt.main(Decrypt.java:125)

Additionally, I am able to decrypt a file (sent from a third-party)
using PGP 6.5.8, but when I try to decrypt it using OpenPGP I get this
exception:

Reading message failed.
cryptix.message.MessageException:

        at
cryptix.message.MessageFactory.generateMessages(MessageFactory.java:134)
        at Decrypt.main(Decrypt.java:103)

As an additional piece of information, the OpenPGP encrypt/decrypt
examples work fine when run alone.

Any help is greatly appreciated,

Rob
