PAKE protocols make use of a range of cryptographic schemes and
primitives. Standards allow for several options to use for each of them.
They call the combination of specific algorithms cipher suites,
configurations or options.
Cipher suites are represented by a separate data type for several
reasons:
1. To allow for individual PAKE protocols to provide pre-defined cipher
suites.
2. To organise cipher suites into a unit that can be handled separately
from the operation context. The PAKE operation flow is already
complex, will be even more so when key confirmation is added.
Handling them separately should reduce the surface of the interface
the application developer needs to pay attention at any given time.
