decrypt abstract method

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

Decrypts ciphertext data using this key.

ciphertext is the encrypted binary data to decrypt. params provides optional algorithm-specific parameters (e.g., "IV" for AES).

Returns the decrypted plaintext as Uint8List, or null if decryption fails.

Implementation

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