## Detailed Description

### template<CipherDir DIR, class BASE>
class BlockCipherFinal< DIR, BASE >

Provides class member functions to key a block cipher.

Template Parameters

  DIR | a CipherDir
  BASE | a BlockCipherImpl derived class

Definition at line 317 of file seckey.h.

## Constructor & Destructor Documentation

## ◆ BlockCipherFinal() [1/4]

template<CipherDir DIR, class BASE>

BlockCipherFinal< DIR, BASE >::BlockCipherFinal | ( |  | ) |
| inline

Construct a default BlockCipherFinal.

The cipher is not keyed.

Definition at line 322 of file seckey.h.

## ◆ BlockCipherFinal() [2/4]

template<CipherDir DIR, class BASE>

BlockCipherFinal< DIR, BASE >::BlockCipherFinal | ( | const byte * | key | ) |
| inline

Construct a BlockCipherFinal.

Parameters

  key | a byte array used to key the cipher

key must be at least DEFAULT_KEYLENGTH in length. Internally, the function calls SimpleKeyingInterface::SetKey.

Definition at line 328 of file seckey.h.

## ◆ BlockCipherFinal() [3/4]

template<CipherDir DIR, class BASE>

BlockCipherFinal< DIR, BASE >::BlockCipherFinal | ( | const byte * | key,
|  | size_t | length
| ) |  |
| inline

Construct a BlockCipherFinal.

Parameters

  key | a byte array used to key the cipher
  length | the length of the byte array

key must be at least DEFAULT_KEYLENGTH in length. Internally, the function calls SimpleKeyingInterface::SetKey.

Definition at line 336 of file seckey.h.

## ◆ BlockCipherFinal() [4/4]

template<CipherDir DIR, class BASE>

BlockCipherFinal< DIR, BASE >::BlockCipherFinal | ( | const byte * | key,
|  | size_t | length,
|  | unsigned int | rounds
| ) |  |
| inline

Construct a BlockCipherFinal.

Parameters

  key | a byte array used to key the cipher
  length | the length of the byte array
  rounds | the number of rounds

key must be at least DEFAULT_KEYLENGTH in length. Internally, the function calls SimpleKeyingInterface::SetKeyWithRounds.

Definition at line 345 of file seckey.h.

## Member Function Documentation

## ◆ IsForwardTransformation()

template<CipherDir DIR, class BASE>

bool BlockCipherFinal< DIR, BASE >::IsForwardTransformation | ( |  | ) | const
| inline

Provides the direction of the cipher.

Returns
  true if DIR is ENCRYPTION, false otherwise
