Detailed Description

AES-192 encryption class (running in Cipher Block Chaining mode)

Member Function Documentation

virtual void uicore::AES192_Encrypt::add ( const void *  data, int  size  )

pure virtual

Adds data to be encrypted.

virtual void uicore::AES192_Encrypt::add ( const DataBufferPtr &  data )

pure virtual

Add data to be encrypted.

Parameters

data	= Data Buffer

virtual void uicore::AES192_Encrypt::calculate ( )

pure virtual

Finalize encryption.

static std::shared_ptr<AES192_Encrypt> uicore::AES192_Encrypt::create ( )

static

Constructs a AES-192 generator (running in Cipher Block Chaining mode)

virtual DataBufferPtr uicore::AES192_Encrypt::data ( ) const

pure virtual

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

virtual void uicore::AES192_Encrypt::reset ( )

pure virtual

Resets the encryption.

virtual void uicore::AES192_Encrypt::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::AES192_Encrypt::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::AES192_Encrypt::set_padding ( bool  value = true, bool  use_pkcs7 = true, unsigned int  num_additional_padded_blocks = 0  )

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)
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)
