secure-compressor

secure_compressor is a Dart package that provides utilities for securely encrypting, decrypting, compressing, and decompressing string data using AES encryption and gzip compression.

Features

• Encrypt and decrypt string data using AES encryption.
• Compress and decompress string data using gzip.
• Combine encryption and compression for secure and efficient data storage and transmission.
• Save encrypted and compressed data to local storage.
• Share encrypted and compressed data to media platform device (WA, email, etc).

Installation

Add the following to your pubspec.yaml file:

dependencies:

secure_compressor: <Latest-Version>

Then, run flutter pub get to fetch the package.

Usages

::: Notes :::
 - keyString must be 32 character
 - Initialization Vector (IV) [ivString] must be 16 character

Encrypt

Encrypt a string using AES encryption:

final result = await  SecureCompressor.encrypt(data, keyString, ivString: ivString);

Compress and then encrypt a string:

final result = await  SecureCompressor.compressAndEncrypt(data, keyString, ivString: ivString);

Decrypt

Decrypt an AES encrypted string:

final result = SecureCompressor.decrypt(encryptedData, keyString, ivString: ivString);

Decrypt and then uncompress a string:

final result = SecureCompressor.uncompressAndDecrypt(compressedAndEncryptedData, keyString, ivString: ivString);

Save Data to Local Storage

Save data to a local file:

	SecureCompressor.saveDataToLocal(fileName, data);

Share Data to Media Platform Device (WA, email, etc)

Share data to a media platform device:

	SecureCompressor.shareFile(fileName, data);

Generate Unix Key

If you wanna generate unix key, you can use this function. NOTE: NEVER USE THIS FUNCTION TO ENCRYPT OR DECRYPT FROM OTHER DEVICE

	await SecureCompressor.getUnixId()

Save Primitif Data Type into Local Storage

Save primitif data type as string, boolean, int, and double into local storage using GetStorage.

Initializes the storage helper with the given parameters first befor run the app:

    await StorageHelper.initialize(
      'YOUR_STORAGE_NAME',
      isEncryptKeyAndValue: true, // Default true
      encryptionKey: "YOUR_ENCRYPTION_KEY_MUST_BE_32_CHAR", // If null, will use unix id from devices used
      isKeyEncrypted: true, // Default true
    );

	StorageHelper.saveString('test_key', 'test_value');
    final savedData = StorageHelper.getString('test_key');
