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.

Installation

Add the following to your pubspec.yaml file:

dependencies:
  secure_compressor: <Latest/Version>

Then, run flutter pub get to fetch the package.

Usages

Encrypt

Encrypt a string using AES encryption:

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

Compress and then encrypt a string:

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

Decrypt

Decrypt an AES encrypted string:

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

Decrypt and then uncompress a string:

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

Save Data to Local Storage

Save data to a local file:

  await SecureCompressor.saveDataToLocal(fileName, data);
