PKWARE Strong Encryption Algorithm


I wonder about PKWARE Strong Encryption algorithm.

ZIP File Format Specification v6.3.5 says about Strong Encryption by PKWARE (7.0 Strong Encryption Specification). This description is not completed and it's impossible to implement this encryption in the application.

I wonder about is there any working source code using this encryption algorithm? Does not matter what language. I'm planning to add it to my own application but did not succeed yet.

P.S. This is not a Traditional PKWARE Encryption, that described in 6.0 Traditional PKWARE Encryption


Solution

  • To my knowledge, there are no open source implementations.

    The strong encryption functionality is patented. If you have not already done so, contact [email protected] to obtain a license.

    After you have a license, if you provide more details about what you think is missing from the description, I can try to help.
