decryptBytes function

Uint8List decryptBytes(
  1. String base64Text,
  2. String keyText,
  3. String ivText
)

Implementation

Uint8List decryptBytes(String base64Text, String keyText, String ivText) {
  keyText = sha512(dart_convert.utf8.encode(keyText)).substring(0, 32);
  ivText = sha512(dart_convert.utf8.encode(ivText)).substring(0, 16);
  final key = encrypt_encrypt.Key.fromUtf8(keyText);
  final iv = encrypt_encrypt.IV.fromUtf8(ivText);
  final encrypter = encrypt_encrypt.Encrypter(encrypt_encrypt.AES(key));
  return Uint8List.fromList(
    encrypter.decryptBytes(
      encrypt_encrypt.Encrypted.fromBase64(base64Text),
      iv: iv,
    ),
  );
}
