    Modifier and Type | Method and Description
    --- | ---
    `byte[]` | Cipher.`doFinal()` Finishes a multiple-part encryption or decryption operation, depending on how this cipher was initialized.
    `byte[]` | Cipher.`doFinal(byte[] input)` Encrypts or decrypts data in a single-part operation, or finishes a multiple-part operation.
    `int` | Cipher.`doFinal(byte[] output, int outputOffset)` Finishes a multiple-part encryption or decryption operation, depending on how this cipher was initialized.
    `byte[]` | Cipher.`doFinal(byte[] input, int inputOffset, int inputLen)` Encrypts or decrypts data in a single-part operation, or finishes a multiple-part operation.
    `int` | Cipher.`doFinal(byte[] input, int inputOffset, int inputLen, byte[] output)` Encrypts or decrypts data in a single-part operation, or finishes a multiple-part operation.
    `int` | Cipher.`doFinal(byte[] input, int inputOffset, int inputLen, byte[] output, int outputOffset)` Encrypts or decrypts data in a single-part operation, or finishes a multiple-part operation.
    `int` | Cipher.`doFinal(ByteBuffer input, ByteBuffer output)` Encrypts or decrypts data in a single-part operation, or finishes a multiple-part operation.
    `protected abstract byte[]` | CipherSpi.`engineDoFinal(byte[] input, int inputOffset, int inputLen)` Encrypts or decrypts data in a single-part operation, or finishes a multiple-part operation.
