How to set PKZip-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 StrongEncryption to True and specify desired encryption parameters using StrongEncryptionInfo property.
Example:
ZipWriter = new TElZipWriter(); ZipWriter.Encrypt = true; ZipWriter.Password = "password"; ZipWriter.StrongEncryption = true; ZipWriter.StrongEncryptionInfo.EncryptionAlgorithm = SBZipUtils.Unit.ZIP_ENCRYPTION_AES128;
