Detailed Description

template<int S>
class AESCounter< S >

Generic AES Counter class.

The template parameter S is the number of bits in the counter.

The underlying counter type can be accessed like this: AESCounter<128>::counter_t

When a counter instance is destroyed, it erases the counter data by setting it to all zeroes.

AESCounter<128> counter = AESCounter<128>::readFromStream(s);

The template parameter S is the number of bits in the counter.
