--------------------------------

[~dstiegli1] This one illustrates my case: 
[https://github.com/srikanth-lingala/zip4j/blob/master/src/test/resources/test-archives/entry_with_checksum_mismatch.zip]

UnpackContent didn't fail on it.

The CRC isn't ok:

 
{code:java}
$ zip -T entry_with_checksum_mismatch.zip 
sample_text1.txt        bad CRC d335ee7a  (should be 003611e7)
test of entry_with_checksum_mismatch.zip FAILED

zip error: Zip file invalid, could not spawn unzip, or wrong unzip (original 
files unmodified) {code}
 

 

> UnpackContent doesn't verify zip checksum
