Encrypting zip files with a password based on Zip 2.0 encryption

I am trying to zip and encrypt files in Java (1.6) with a password based on the earlier Zip 2.0 encryption. I have used AES 256 bit encrytpion to encrypt zip files with password and have successfully been able to do so.

Though AES is a stronger and a more secure encryption standard, i need to find a standard that is more widely supported across all zip clients so that the users have a higher success rates opening the password protected zip files. So i was looking for some Zip 2.0 based encryption to encrypt my files. An开发者_如何转开发y help would be appreciated!

Thanks!

I think that nearly all zip-clients do support the WinZip-AES-encryption. As WinZip is far more spread than the original pkzip, it's encryption has become the de-facto standard. Do you have a specific client which does not support the aes-encryption?
