Create secure or standard self-extracting files from ZIP files. 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. Chilkat's streaming compression and encryption technology allows this software to create an EXE from any size ZIP file. The streaming compression and decryption technology also ensures that it will be possible to unzip the archive on your end-user's computer, even if that computer has very little memory.
