[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:

Does anybody have an idea, why this happens ?

Thanks a lot
