Description:

zip encryption

zip_encryption #
zip_encryption is a Flutter package that provides functionality for encrypting and decrypting ZIP files on Windows. This package uses a simple XOR encryption method to secure the contents of ZIP files, making it easy to store and share encrypted data.
Features #

Encrypt any ZIP file with a specified key.
Decrypt any encrypted ZIP file with the specified key.
Store the encrypted and decrypted files at user-defined paths.
Easy-to-use API for encryption and decryption.
Designed specifically for Windows.

Getting Started #
To start using zip_encryption, add it to your pubspec.yaml file:
dependencies:
zip_encryption:
git:

Then, run flutter pub get to install the package.
Usage #
Here's an example of how to use the zip_encryption package in your Flutter project.
Encrypt a ZIP File #
import 'package:zip_encryption/zip_encryption.dart';

void main() async {
ZipEncryption zipEncryption = ZipEncryption(123);
final bool success = await zipEncryption.encryptAndStoreZip(
zipFilePath: 'C:\\path\\to\\your\\file.zip',
encryptedFilePath: 'C:\\path\\to\\store\\encrypted_file.zip'
);

if (success) {
print('File encrypted successfully');
} else {
print('Failed to encrypt file');
}
}
copied to clipboard
Decrypt a ZIP File #
import 'package:zip_encryption/zip_encryption.dart';

void main() async {
ZipEncryption zipEncryption = ZipEncryption(123);
final bool success = await zipEncryption.decryptAndStoreZip(
encryptedFilePath: 'C:\\path\\to\\encrypted_file.zip',
decryptedFilePath: 'C:\\path\\to\\store\\decrypted_file.zip'
);

if (success) {
print('File decrypted successfully');
} else {
print('Failed to decrypt file');
}
}

API Reference #
ZipEncryption #
The ZipEncryption class provides the core functionality for encrypting and decrypting ZIP files.
Constructor #
ZipEncryption(int key)
copied to clipboard
key: The encryption key used for XOR encryption.
Methods #
Future
Encrypts the specified ZIP file and stores the encrypted file at the given path.

Parameters:

zipFilePath: The path to the ZIP file to be encrypted.
encryptedFilePath: The path where the encrypted file will be stored.


Returns true if the operation is successful, otherwise false.

Future
Decrypts the specified encrypted ZIP file and stores the decrypted file at the given path.

Parameters:

encryptedFilePath: The path to the encrypted ZIP file.
decryptedFilePath: The path where the decrypted file will be stored.


Returns true if the operation is successful, otherwise false.

Design #
The zip_encryption package is designed to provide a simple and efficient way to encrypt and decrypt ZIP files on Windows. The encryption method used is XOR encryption, which is lightweight and fast. This package is intended for use cases where basic encryption is sufficient.
Key Components #

XOR Encryption: The package uses XOR encryption to encrypt and decrypt the contents of ZIP files. This method is chosen for its simplicity and speed.
File Operations: The package handles reading from and writing to files, making it easy to store encrypted and decrypted files at user-specified locations.
Error Handling: The package includes basic error handling to manage issues such as missing files or incorrect paths.
