An option to ignore crc errors

[srikanth-lingala]

I am wondering why would you need that? A file extracted without a valid crc is a corrupt and invalid file. You might as well have create a file with random bytes in it. I am trying to understand a use case behind it.

I wrote a java application and I dont want someone else to extract the data pack of mine,so I deliberately broken the crc of it,I will verify my data in an other way.But when I tried to extract the pack i found that zip4j hasnt a option to ignore crc errors.I done it with a custom patch on it.

Why don't you set a password to the zip file if you wan't no one to be able to extract the file?

It is a traditional way,there are many ways to brute force attack on it.But you are right,i can encrypt my data instead of encrypt the zip file.

AES encryption has significantly greater security and protection than the traditional zip encryption (ZIP_STANDARD in zip4j).
