Constructor & Destructor Documentation

AdvancedEncryptionStandard()

AdvancedEncryptionStandard::AdvancedEncryptionStandard ( const uint8 *  key, Cipher  cipher, bool  inverse = false  )

noexcept

Initializes encryption object.

Parameters

key	The key.
cipher	The cipher.
inverse	Specifies if the inverse cipher should be used. The default is false.

Member Function Documentation

getKeyLenght()

static unsigned int AdvancedEncryptionStandard::getKeyLenght ( Cipher  cipher )

inlinestaticnoexcept

Returns the key length in bytes for the specified cipher.

push()

unsigned int AdvancedEncryptionStandard::push ( uint8 *  dest, const uint8 *  src, unsigned int  size  )

noexcept

Encrypts the specified data. May be called multiple times.

Parameters

dest	The cipher text.
src	The buffer holding the data to be encrypted (plain text).
size	The number of octets in the buffer.

Returns

The number of bytes written.

pushEnd()

unsigned int AdvancedEncryptionStandard::pushEnd ( uint8 *  dest, unsigned int  size  )

noexcept

This function should be invoked when the entire message has been pushed. Do NOT use push() after invoking this function.

Parameters

dest	The cipher text.
size	The number of octets in the buffer.

Returns

The number of bytes written.
