Chilkat Zip is a zip / unzip ActiveX component with AES encryption, self-extracting EXE features, built with Chilkat streaming technology for high-performance and low memory usage. It has many advanced features including: Encrypt your data using up to 256-bit AES encryption. It also supports Blowfish and Twofish encryption algorithms. Embed ZIP files directly into EXEs, and access them from your program. The ZIP is embedded as a named resource, and any number of ZIPs can be embedded in a single EXE. It works with the ChilkatZip Self-Extractor utility to access ZIPs embedded in EXEs created by that utility. Unzips files based on last-modification time. Exclude files matching wildcarded filenames, such as "*.log". Create new ZIPs from existing files, memory data, or other existing ZIPs.
