[Cryptix-users] help with cryptix openpgp

[Francisco J. R. L. <fra...@gm...>]

Hi everybody,

I am new with cryptography stuff and I am working on a program that needs to
encrypt and sign large files using cryptix openpgp, I am currently running
the samples GenereteAndWriteKey and StreamEncrypt, then I am going to run
StreamEncryptSign example.

I am working on Windows XP Professional, Java SE 5, MyEclipse 6.

For now, I have the following jar files in a lib folder in my MyEclipse
project:

certpath-api-compat.jar
cryptix-jce-provider.jar
cryptix-message-api.jar
cryptix-openpgp-provider.jar
cryptix-pki-api.jar

I have a question for the moment,

How a Key/Key pair can be generated with an expiration date?
In the GenerateAndWriteKey example, running on debug mode, in the
watch/inspect variables, each key, pubkey and privkey has a packet member;
this packet contains an expire member (int).

What does it mean that expiration date and what values are permitted to this
variable?

I guess the value 0 means never expires.

Regards and thank you for your time,
Francisco Rosas

[Cryptix-users] Special characters for passphrase for OpenPGP keys

[Alice AU <al...@ms...>]

Hi guys,
=20
       Have tried searching the mailing list + the Internet, but amstill no=
t sure if special characters, like  ~!@#$%^&*()_+, is fine to beincluded in=
 the passphrase. Do any one know about it?

Hello guys,

[Cryptix-users] Possible to StreamEncrypt to 2 public keys?

[Bill L. <bl...@ya...>]

Hi,

I am using the cryptix libraries to encrypt files using a program very similar to StreamEncrypt.java provided in the cryptix.openpgp.examples package.  Commercial versions of PGP (Unix, Windows) include the ability to encrypt files to more than 1 public key.  Is it possible to stream encrypt a file to more than 1 public key at at time using the cryptix open source libraries?

Thanks,
Bill Lyons

[Cryptix-users] Problem NoSuchAlgorithmException

[Denis B. <den...@co...>]

Hi folks,

I user Cryptix for PGP encryption/decryption. When I make local tests:
ecnrypt/decrypt - there is not problem.
And when I install my code to WebSphere - most of time - no problems.

But rarely on WebSphere applicaton throws different exceptions like:
java.lang.IllegalArgumentException: id not found -
java.security.NoSuchAlgorithmException: Cipher #3 not found vmcid: 0x0 minor
code: 0 completed: No

Or ElGamal algorithm not found.

I think that problem with providers location during runtime.

But I have registered security providers in my code this way
java.security.Security.addProvider(
new cryptix.jce.provider.CryptixCrypto() );
java.security.Security.addProvider(
new cryptix.openpgp.provider.CryptixOpenPGP() );

Re: [Cryptix-users] Question of OpenPGP implementation

[Xavier, J. <c-j...@st...>]

Hi,

Is there a openPGP implementation for encryption using passphrase?  The
current implementation does not have it.  The version that I am using is
cryptix-openpgp-20050418-snap.zip
<http://www.cryptix.org/cryptix-openpgp-20050418-snap.zip>=20

[Cryptix-users] P.S. Read tried past end of inputstream

[Hartmut K. <har...@ha...>]

Dear all

I want to add something important concerning my problem.

If I use non-streaming example-files like EncryptAndSign.java or 
DecryptAndVerify.java there is no exception.
I just get the exception message by using streaming-classes for 
encrypting/signing AND for decrypting/verifying.

You can get the data-file data.dat.9 which produces the error at 
www.hauk-sasko.de/data.dat.9

thanks a lot anybody trying to reproduce the exception behaviour and - 
hopefully - finding out the problem.

Regards, Hartmut




Again, my problem:

Dear all,

I tried to use the example-files StreamEncryptSign.java and
StreamDecryptVerify.java to encrypt/sign and decrypt/verify
a binary file.

Therefor, in the file StreamEncryptSign.java I changed the part:

for (int i=0; i<10000; i++) // we write to literal
litmos.write( (i+" This is a large message.
\r\n").getBytes() );
litmos.close();

in
File f = new File("data.dat.9");
FileInputStream fileis = new FileInputStream(f);
byte[] buf = new byte[(int) f.length()];
fileis.read(buf);
litmos.write(buf);
fileis.close();
litmos.close();


By using StreamDecryptVerify.java for decrypting/verifying the encrypted and
signed binary file
I get the following messages:

Your reading from and writing to an unbuffered file-stream. Dependent
on the operating-system this might be unbuffered. To find out where
the time is lost, just comment out the fileOutputStream.write-method.
If the time drops significantly, it's not the encoding but the file-
operation being done.

The decoding itself shouldn't take too long, because a symmetric
crypt-algorithm is used.

Another option is to start up a Profiler that shows you where
CPU-cycles are lost.

BTW: Your while-loop can be changed in a way that only one read-method
is being used:

int len;
while ((len = decodedInputStream.read(buf)) > 0){
    fileOutputStream.write(buf, 0, len);
}

[Cryptix-users] Problem decrypt large file

[Stefania V. <ste...@en...>]

Hello,

 I have written a java class using the cryptix libraries for the =
signature/encryption and decryption/verification of files.

 I used these classes for the streams and everything worked properly as =
long as the files were not to large. =20

 However, when I tried to decrypt a 400MB file it took about 30 minutes.

 I used the example of the "StreamDecryptVerify" libraries to implement =
my class but I would like to know if something is out of place or if it =
is possible to improve the efficiency of the class.

No, but try to create a file that reproduces this behavior and give

Does BC have the PGP capability?

"This is my public key" is not a PGP key, obviously. I don't know how
much you know about encryption but it sounds like you're confusing the
actual key with the passphrase.

Anyway, as the "latest" Cryptix release is more than two years old,
you're probably riding a dead horse. We switched to BC quite a while
ago (http://www.bouncycastle.org/) and never looked back. It's got way
better documentation/examples and is actively developed.

PGPLiteralMessageImpl is not a subclass of KeyBundleMessage, so casting
to it must lead to this exception. You should cast to Message and check
for the type of the class before doing a more concrete cast.

[Cryptix-users] java.lang.ClassCastException: cryptix.openpgp.provider.PGPLiteralMessageImpl

[ikiliklip i. <iki...@ya...>]

Hi everyvody!

I'm trying to read the content of bob-public.pgp.asc file. Well, the code where the error is thrown is that:

in = new FileInputStream("bob-public.pgp.asc");
 msgs = mf.generateMessages(in);
kbm = (KeyBundleMessage) msgs.iterator().next();
publicBundle = (PGPKeyBundle) kbm.getKeyBundle();
in.close();


When the content of this file is a key generated by crytix, it works. But when I put in the file a simple string "This is my public key" as a key, the error I get is:

java.lang.ClassCastException: cryptix.openpgp.provider.PGPLiteralMessageImpl

Do you know why? If I convert the string to base64, i get the same error. I'm doing something wrong, but I don't know what it is!! Help me, please!!! I would appreciate any hint!

Thanks, 

Regards

Re: [Cryptix-users] Cryptix and jdk 1.5

[Lothar K. <jo...@ki...>]

Hello,

you can fix the problem by defining a wrapper-class:

--------------- snip
package whatever;

import java.util.Enumeration;

import cryptix.provider.Cryptix;

/**
 * Own Provider for enabling Cryptix on Java Versions > 1.5
 * @author Lothar Kimmeringer <lo...@ki...>
 *
 */
public class CryptixNewerJavaProvider extends Cryptix {

    /**
     * Creates a new instance of this provider
     */
    public CryptixNewerJavaProvider() {
        super();
        Enumeration props = propertyNames();
        while (props.hasMoreElements()){
            String key = (String) props.nextElement();
            put(key, getProperty(key));
        }
    }

}
--------------- snip

and register "your own" provider before you try to use Cryptix:

java.security.Security.addProvider(new CryptixNewerJavaProvider());

Works fine here and need no change of the cryptix-sources.


Best regards,

Lothar Kimmeringer

Re: [Cryptix-users] Encrpting/ Decrypting pdf and zip files

[Matt F. <mf...@fi...>]

Haven't read the whole lot of the code but it looks like the problem 
lies here...

BufferedReader in = new BufferedReader(new FileReader(fromFileName));

Surely this will not work on a binary file?  A buffered reader will 
corrupt binary data as it gets converted into text...
This isn't a cryptix issue but a plain old Java issue.  You can prove it 
by reading the file in and writing it out again without encrypting / 
decrypting and check if it's the same issue...
Also FileReader is for character files not binary ones...
Use FileInputStream
eg...
FileInputStream in = new FileInputStream(new File(fromFileName));

Should now work for binary and textual files.

[Cryptix-users] Encrpting/ Decrypting pdf and zip files

[Geetu S. <gee...@gm...>]

Hi Friends,
I am posting for the first time, so I hope I am adhering to etiqette of the
forum.

I am facing a problem while encrypting/ decrypting of zip and pdf files.
Is it possible to use cryptix on binary files?

The exact problem is:
On decrypting, the zip gives me a CRC error on extracting and all extracted
files have zero size.
On decrypting, the pdf files have a size matching the original raw pdf but
it is all blank inside.

I have tried quite a few ways of using cryptix but nothing worked (it works
on plain txt files).
Nothing on net says anything on the matter. Please help.


I am using stream encryption/ decryption.
My code is


    public void encrypt(String fromFileName, String toFileName) throws
IOException, CipherException {

        try {
            FileOutputStream fileos = new FileOutputStream(toFileName);
            LiteralMessageOutputStream litmos =
LiteralMessageOutputStream.getInstance("OpenPGP");
            EncryptedMessageOutputStream encmos =
EncryptedMessageOutputStream.getInstance("OpenPGP");
            SecureRandom sr = new SecureRandom();

            litmos.init(encmos, sr);   // Literal writes to Encrypted
            encmos.init(fileos, sr);   // Encrypted writes to file

            encmos.addRecipient(publicKeyBundle);

            BufferedReader in = new BufferedReader(new
FileReader(fromFileName));

            int ch;
            while ((ch = in.read()) != -1) {

                litmos.write(ch);
            }
            in.close();

            litmos.close();

        } catch (NoSuchAlgorithmException nsae) {
            throw new CipherException(noSuchAlgorithmMessage);
        } catch (MessageStreamException me) {
            throw new CipherException("Streaming the message failed.");
        } catch (IOException ioe) {
            throw ioe;
        }
    }

    public void decrypt(String fromFileName, String toFileName) throws
IOException, CipherException {

            decodedInputStream = DecodedMessageInputStream.getInstance

            decodedInputStream.init(fileInputStream, this, this);

Re: [Cryptix-users] Unsupported keysize or algorithm parameters

[Eric B. <Eri...@We...>]

This is a similiar issue I was running into using the JCE RC4 =
encryption.  The only way I could get the code below to work was using a =
maximum of 16 characters as the key, which is pretty weak.  I couldn't =
find and policy files and such.
=20
All I am trying to do is RC4 encrypt a string using another string that =
is 128 characters long as the string, and I am failing miserably.

                 java.security.Security.addProvider(new =
cryptix.jce.provider.CryptixCrypto());
                 RawSecretKey v_key =3D new RawSecretKey("RC4", =
"GFgksgjGNDKGlsgnLDGGknhjLdgnLSgnlsdkgNLSkgnlesnvlKENVlkENVLkNELVknLEKVns=
ev".getBytes());
                 alg =3D Cipher.getInstance("RC4","CryptixCrypto");
                 alg.init(Cipher.ENCRYPT_MODE, v_key );
