[Cryptix-users] decodedInputStream.init out of memory on uncompressed long files

[Ale <ale...@da...>]

Hello list,

I'm experiencing a problem when decrypting uncompressed files generated
with GnuPG version

gpg (GnuPG) 1.2.7

with the following command line:

gpg -z 0 --disable-mdc --batch --yes -o out.gpg -r 'fpr' --encrypt in.file


I'm using the example provided with the cryptix snapshot version:

Cryptix OpenPGP  	snapshot  	2005/04/18  	
Cryptix JCE  		snapshot  	2005/03/28

The problem is that when I try to decrypt a file, to say, of about 10 Mb
and using a heap size of 256Mb (that to me seems way to big anyway), the
engineInit for decodedInputStream takes a long time but it can decrypt
the message.
When trying to decrypt a bigger file, that is about 90 Mb, the
engineInit takes a long time and after that long time, I get an
OutOfMemory exception (even with -Xmx256m).

- Format: OpenPGP:CryptixOpenPGP version 0.20050418
- before init..
- decryption key return..
- Decryption key returned
cryptix.message.stream.DecryptionKeyReturnValue@65a77f
-Exception in thread "Thread-5" java.lang.OutOfMemoryError: Java heap space


When trying to decrypt files, encrypted without the -z 0 gpg option, the
init process seems to be ok, it takes a very short time, but with the
90Mb file, the read() method of decodedInputStream throws an exception of:

Error: java.io.IOException: Fatal data format exception: Read tried past
end of inputstream.

Seems that the file has been trunked an amount of file always less then
the buffer size that is 4096 bytes.

Any help will be appreciated, infact if we can overcome this problem, we
will continue using this software in a production enviroment, even with
some sort of commercial relationship.

[Cryptix-users] Getting Cipher instance fails when setting up https connection

[Roodzant, M. <Mar...@Ge...>]

Hi,

I hope someone can point me in the right direction with the following.

Our application (which was built with jdk1.3 and Cryptix-3.2.0.jar) sets =
up a https connection.
Now we have (finally) upgraded to 1.5.

I did gather that Cryptix-3.2.0 should not be used in conjuction with =
any jdk from 1.4 upwards.
And I did put the following jars on the classpath (probably overdoing =
things a bit)
    cryptix-jce-api.jar
    cryptix-jce-compat.jar
    cryptix-jce-provider.jar
    cryptix-jce-tests.jar
As the jsse.jar is included with the jdk. I removed this jar from the =
application classpath.

All to no avail. Before and after doing all that the result is the =
following stacktrace.

java.lang.NoClassDefFoundError

[Cryptix-users] Decryption with multiple keys

[Aredeji D. <ar...@ho...>]

Hi,

I am having problems decrypting a file that has been encrypted using two or 
more keys. If a file has been encrypted with two or more keys I can decrypt 
the file using only the first key that was used during the encryption. For 
example, if a file was encrypted using user1 and user2 public keys, it can 
only be decrypted using the user1's private key. When decrypting using the 
user2's private key I get the following exception:
java.lang.RuntimeException: TT
	at 
cryptix.jce.provider.rsa.RSACipher_ECB_PKCS1.engineDoFinal(RSACipher_ECB_PKCS1.java:209)
	at 
cryptix.jce.provider.rsa.RSACipher_ECB_PKCS1.engineDoFinal(RSACipher_ECB_PKCS1.java:178)
	at javax.crypto.Cipher.doFinal(DashoA12275)
	at cryptix.openpgp.algorithm.PGPRSA.decrypt(PGPRSA.java:614)
	at 
cryptix.openpgp.packet.PGPPublicKeyEncryptedSessionKeyPacket.decrypt(PGPPublicKeyEncryptedSessionKeyPacket.java:189)
	at 
cryptix.openpgp.provider.PGPDecodedMessageInputStream.engineInit(PGPDecodedMessageInputStream.java:216)
	at 
cryptix.message.stream.DecodedMessageInputStream.init(DecodedMessageInputStream.java:144)
	at bscw.apps.functions.DecryptFunctions.decrypt(DecryptFunctions.java:108)

If I use other applications to decrypt the file using the user1 or the user2 
key it seems to work fine. How can I fix this?

Thank you,
Ared

Encryption on our web site, has suddenly (an apparently without reason)
stopped working.  All attempts to use the Cryptix libs result in
exceptions such as:

java.lang.NoClassDefFoundError: javax/crypto/f
at javax.crypto.Cipher.getInstance(Unknown Source)


The site has been working with encryption for two years with no
problems, so I'm somewhat baffled as to why it's suddenly stopped.  Any
ideas would be appreciated.

No clue, sounds like a bug.  I'll just offer that the jars I found at
bouncycastle.org work well for non-signed files of large and various size.
I can't get their stuff to work for signed files though.

FW: [Cryptix-users] Problem with Cryptix JCE Provider

[Kapadi, A. <AK...@ti...>]

Hi,
=20
  I was able to solve the problem I had below. Now I am able to encrypt the=
 Text or ASCII file using Cryptix but when the file size is big (>10Mb), it=
 takes a long time to do the encryption. The following is code snippet I am=
 using.=20
=20
 java.io.BufferedReader in =3D new java.io.BufferedReader(new java.io.FileR=
eader(new java.io.File(textFile)));
            String line =3D null;
            while ((line=3Din.readLine()) !=3D null) {
                msg =3D msg.concat(line);
                msg =3D msg.concat("\n");
            }
            in.close();
            LiteralMessageBuilder lmb =3D LiteralMessageBuilder.getInstance=
("OpenPGP");
            lmb.init(msg.getBytes());
            litmsg =3D (LiteralMessage) lmb.build();=20
=20
I used to pass the string object to INIT method of LiteralMessageBuilder bu=
t changed to bytes assuming it would be faster. It is faster compared to wh=
en I used to pass the string but still it takes around 2hrs+ to encrypt any=
 file bigger than 10Mb. Did any one encounter this problem? Any suggestions=
 to improve the speed?=20

[Cryptix-users] compression

I am using the EncryptedMessageOutputStream to encrypt but not sign a

file is much larger than the original.  The original 6.4 M text files
produces a 6.45M encrypted file.  It is my understanding that
compression occurs automatically.  I tried setting the "compressed"

Hi everyone,

during Cryptix installation, the local_policy.jar has to be placed in =
folder java/jre/lib/security.

Just wondering if anyone knows of a software workaround where the policy =

If you have any coding examples I would be really grateful.

Hi,
Could anybody help with NegativeArraySizeException or ArrayIndexOutOfBoundsException

java.lang.NegativeArraySizeException
	at cryptix.jce.provider.cipher.BlockCipher.engineDoFinal(BlockCipher.java:377)
	at javax.crypto.Cipher.doFinal(DashoA6275)
	at com.futuretrade.common.FTOcryptixEncoder.decode(FTOcryptixEncoder.java:171)

We expecting this problem during application webstart run.

Actually problem appears when before decoding aplication do some recources 
extraction from jar files and works with URL object.

We were unable to reproduce this problem on local machine without webstart.

Data for decoding was "2DA2015CB6C13740" and cipher initialization was done like:
KeyGenerator keygen = KeyGenerator.getInstance( "DES",									  "CryptixCrypto" );
			SecureRandom random = new SecureRandom( seed );
			keygen.init( random );
			key    = keygen.generateKey();
			cipher = Cipher.getInstance( "DES/ECB/PKCS5Padding",
	 "CryptixCrypto" );
