Create self-extracting ZIP files optionally with unbreakable AES encryption. The ChilkatZip Self-Extractor can safely encrypt the contents of your ZIP file with 128, 192, or 256-bit AES Encryption. To unzip, a user must provide the same password that was used when creating the self-extracting EXE. AES encryption is much stronger than standard ZIP encryption, which is regarded by security experts as being unsecure. Chilkats streaming compression and encryption technology permit the ChilkatZip Self-Extractor to produce an EXE from any size ZIP file. The streaming compression and decryption technology as well ensures that it will be possible to unzip the archive on your end-users PC, even if that PC has very little memory.
