How to set WinZip-compatible strong encryption
To use WinZip AES encryption, specify Password, then set Encrypt property to True. The archive will be encrypted after compression.
Next set WinZipEncryption to True. You can specify encrypting key size via WinZipAesKeySize property.
Example:
ZipWriter = new TElZipWriter(); ZipWriter.Encrypt = true; ZipWriter.Password = "password"; ZipWriter.WinZipEncryption = true; ZipWriter.WinZipAesKeySize = 128;
