decrypt abstract method

Uint8List? decrypt(
  1. Uint8List ciphertext, [
  2. Mapping? params
])

Decrypts ciphertext data using this key.

ciphertext: Encrypted binary data to decrypt

params: Optional algorithm-specific parameters (e.g., "IV" for AES)

Returns: Decrypted plaintext as Uint8List, or null if decryption fails

Implementation

Uint8List? decrypt(Uint8List ciphertext, [Mapping? params]);
