Member Function Documentation

template<int keybits>

void Rijndael::ECB< keybits >::decrypt	(	const Block	ciphertext,
		Block	plaintext
	)

Decrypt a block of 16 bytes.

Parameters

[in]	ciphertext	The 16 bytes block of data to decrypt.
[out]	plaintext	Space to store the 16 bytes result block.

template<int keybits>

void Rijndael::ECB< keybits >::encrypt	(	const Block	plaintext,
		Block	ciphertext
	)

Encrypt a block of 16 bytes.

Parameters

[in]	plaintext	The 16 bytes block to encrypt.
[out]	ciphertext	Space to store the 16 bytes of encrypted data.

template<int keybits>

Word32 Rijndael::ECB< keybits >::get_random

(

)

Crypto base PRNG.

Based on wall-clock value and current key, but should be a crypto-secure generator.

template<int keybits>

void Rijndael::ECB< keybits >::setupDecrypt

(

const Key

key

)

Initialize decryption state.

Parameters

[in]

key

AES key, where length is: keybits number of bytes 128 16 192 24 256 32

KEYLENGTH macro.

Rijndael::ECB<128>::Key key = "my big secret";
Rijndael::ECB<128> dec;
dec.setupDecrypt(key);
...
Rijndael::Block cipher = ...;
Rijndael::Block result;
Rijndael::decrypt(cipher, result);

template<int keybits>

void Rijndael::ECB< keybits >::setupEncrypt

(

const Key

key

)

Initialize encryption state.

Parameters

[in]

key

AES key, where length is: keybits number of bytes 128 16 192 24 256 32

See also

KEYLENGTH macro.

Rijndael::ECB<128>::Key key = "my big secret";
Rijndael::ECB<128> enc;
enc.setupEncrypt(key);
...
Rijndael::Block plain = "Hello World!";
Rijndael::Block result;
enc.encrypt(plain, result);
