Description Andrzej Taramina 2003-10-28 00:27:08 UTC

Sure would be nice if the zip core task allowed you to specify a password that 
would then be used to encrypt the included files, per the zip standard.

Basically the same as specifying the -s option for pkzip version 2.04g.

Thanks.

java.util.zip does not support passwords, which is what the <zip> task is based 
on.

Comment 2 Dominique Devienne 2003-10-31 22:13:52 UTC

No quite. <zip> is based on import org.apache.tools.zip. --DD

What is the feasibility for adding support for this? It would be nice to not 
have to use winzip or other utils to create the protection.

Thanks,
Chris

1. it would need to be implemented by people who care about the function, which
means only those people who want the feature.

2. it will be a nightmare to test. 

3. winzip standard encryption is breakable by brute force, the non-standard ones
are non-standard and so not really feasible. 

there is some work on in jakarta commons on doing PGP encrypt/sign with the
BouncyCastle libraries.

well, there is theory, though nothing tangible yet.
