RE: [Cryptix-users] Unexpected end of ZLIB input stream

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

Ive seen this problem a while ago.  Its got to do with the InputStream that gets created on top of the compressed datastream.  In
our case, the file we were trying to decrypt contained a whole bunch encrypted null characters.  It seems that as read() extracts
the nulls from the compressed stream, enough nulls in a row signals the InputStream that the end of stream has been reached, even
though available() says theres more to go.
Im sorry if this is a bit vague, it was a couple of years ago.  Check the contents of the file you're trying to decrypt (assuming
you have access to it before it got encrypted).  And if you're really keen, run through the cryptix source and you'll find the exact
line where the problem occurs.
Roger.

Subject: [Cryptix-users] Unexpected end of ZLIB input stream


Decrypting a text document not encrypted by Cryptix(PGP 8.0 for Windows)
generated the following stak trace :

Exception in thread "main" java.lang.RuntimeException: IOException on
ByteArrayInputStream,

        at be.codenet.cps.util.PGP.main(PGP.java:580)

Any ideas ? BTW I checked the previous exchange of messages sent to this
alias and didn't find anyting.

Thanks,
