    Neither the Xceed Zip Compression Library, Xceed Zip for .NET nor Xceed Zip for .NET Compact Framework has no strong encryption at all. It only has password-scrambling that is 100% compatible with the PKZip 2.04g Zip file format. This is ‘light’ protection that will not protect against any determined users. At best, you can consider it has 32-bits of protection.

    The Wassenaar agreement (http://www.wassenaar.org) stipulates that anything under 64-bits of protection for a REAL symetrical algorithm is freely exportable. The password-scrambling built into Xceed Zip is not even real symetrical encryption, it is more a CRC-based password-scrambler, considered as light protection only.

    If you need strong encryption, with real protection, then you may need to be careful about exporting, like if you use the Xceed Encryption Library or any component that supports the AES (Rijndael) or other 128-bit+ encryption algorithms.
