AES-256 decryption class (running in Cipher Block Chaining mode)
| virtual void uicore::AES256_Decrypt::add |
( |
const void * |
data, |
|
|
int |
size |
|
) |
| |
|
pure virtual |
Adds data to be decrypted.
| virtual void uicore::AES256_Decrypt::add |
( |
const DataBufferPtr & |
data | ) |
|
|
pure virtual |
Add data to be decrypted.
- Parameters
-
| virtual bool uicore::AES256_Decrypt::calculate |
( |
| ) |
|
|
pure virtual |
Finalize decryption.
IMPORTANT, to avoid timing attacks, if this function fails, you should still validate the data (via a hash or otherwise), then throw an error
- Returns
- false = AES Padding value is invalid.

Constructs a AES-256 generator (running in Cipher Block Chaining mode)
Get decrypted data.
This is the databuffer used internally to store the decrypted 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

| virtual void uicore::AES256_Decrypt::set_iv |
( |
const unsigned char |
iv[iv_size] | ) |
|
|
pure virtual |
Sets the initialisation vector.
This should be a random number
This must be called before the initial add()
| virtual void uicore::AES256_Decrypt::set_key |
( |
const unsigned char |
key[key_size] | ) |
|
|
pure virtual |
Sets the cipher key.
This must be called before the initial add()
| virtual void uicore::AES256_Decrypt::set_padding |
( |
bool |
value = true, |
|
|
bool |
use_pkcs7 = true |
|
) |
| |
|
pure virtual |
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) |
