AesCbcDecryptor class final

AES-CBC decryption (SP 800-38A) as an incremental whole-block transform.

Used by 7z (AES-256), RAR5 (AES-256), and RAR4 (AES-128), all of which pad ciphertext to 16 bytes and truncate the plaintext by known size, so there is no padding scheme here: callers hand in complete blocks and slice the output themselves. Sequential calls chain (the last ciphertext block carries over), matching a stream decrypted in chunks.

Constructors

AesCbcDecryptor(Aes _cipher, Uint8List iv)

Creates a decryptor over cipher starting from iv (16 bytes).

Methods

decryptInPlace(Uint8List data, [int start = 0, int? end]) → void

Decrypts data[start..end) in place; the length must be a multiple of 16.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.
