Host Functions

The following utility functions should be called from the host. They follow the usual CUDA stream semantics.

template<class PQC>
uint8_t *make_workspace(

size_t batch,

cudaStream_t stream = 0,

);

Allocate the global memory workspace for the algorithm described by PQC sufficient for batch batches. If there is a problem with memory allocation this function will throw a runtime error.

template<class PQC>
uint8_t *get_entropy(

size_t batch,

cudaStream_t stream = 0,

);

Allocate and fill the entropy buffer using cryptographically secure randomness for the algorithm described by PQC, sufficient for batch batches. If there is a problem with memory allocation this function will throw a runtime error.

void destroy_workspace(uint8_t *workspace, cudaStream_t stream = 0);

Release the global memory allocated by make_workspace.

void release_entropy(uint8_t *workspace, cudaStream_t stream = 0);

Release the global memory allocated by get_entropy.
