AES-192 encryption class (running in Cipher Block Chaining mode)
◆ AES192_Encrypt()
clan::AES192_Encrypt::AES192_Encrypt |
( |
| ) |
|
Constructs a AES-192 generator (running in Cipher Block Chaining mode)
◆ add() [1/2]
void clan::AES192_Encrypt::add |
( |
const DataBuffer & | data | ) |
|
Add data to be encrypted.
- Parameters
-
◆ add() [2/2]
void clan::AES192_Encrypt::add |
( |
const void * | data, |
|
|
int | size ) |
Adds data to be encrypted.
◆ calculate()
void clan::AES192_Encrypt::calculate |
( |
| ) |
|
◆ get_data()
DataBuffer clan::AES192_Encrypt::get_data |
( |
| ) |
const |
Get encrypted data.
This is the databuffer used internally to store the encrypted data. You may call "set_size()" to clear the buffer, inbetween calls to "add()" You may call "set_capacity()" to optimise storage requirements before the add() call
◆ reset()
void clan::AES192_Encrypt::reset |
( |
| ) |
|
◆ set_iv()
void clan::AES192_Encrypt::set_iv |
( |
const unsigned char | iv[iv_size] | ) |
|
Sets the initialisation vector.
This should be a random number
This must be called before the initial add()
References iv_size.
◆ set_key()
void clan::AES192_Encrypt::set_key |
( |
const unsigned char | key[key_size] | ) |
|
Sets the cipher key.
This must be called before the initial add()
References key_size.
◆ set_padding()
void clan::AES192_Encrypt::set_padding |
( |
bool | value = true, |
|
|
bool | use_pkcs7 = true, |
|
|
unsigned int | num_additional_padded_blocks = 0 ) |
Enable AES Padding.
Example (use_pkcs7==true) : ... 0x03 0x03 0x03 (3 octets of padding) Example (use_pkcs7==false) : ... 0x02 0x02 0x02 (3 octets of padding, the last octet is the length)
- Parameters
-
value | = true = Enable padding (default) |
use_pkcs7 | = true = This uses the PKCS#7/RFC3369 method (Enabled by default). false = use the TLS method (rfc2246) |
num_additional_padded_blocks | = (Only valid when use_pkcs7==false). Set to "frustrate attacks on a protocol based on analysis of the lengths of exchanged messages". (Range 0 to 15) |

◆ iv_size
const int clan::AES192_Encrypt::iv_size = 16 |
