int BPU_mecsInitCtx	(	BPU_T_Mecs_Ctx **	ctx,
		const BPU_T_UN_Mecs_Params *	params,
		const BPU_T_EN_Mecs_Types	type
	)

Initialize (register) mecs functions for encryption, decryption and key gen based on type.

int BPU_mecsInitParamsQcmdpc	(	BPU_T_UN_Mecs_Params *	params,
		const uint16_t	m,
		const uint16_t	n0,
		const uint16_t	w,
		const uint16_t	t
	)

Wrapper for param initialization. After work you have to free memory using call BPU_mecsFreeParamsQcmdpc

Parameters

params	pointer to structure
m	size of cyclic matrix
n0	number of cyclic matrices
w	weight of parity-check matrix row
t	count of errors

Returns
