config TINYCRYPT
	bool "TinyCrypt Support"
	---help---
		This option enables the TinyCrypt cryptography library.

if TINYCRYPT
config TINYCRYPT_VERSION
	string "Tinycrypt Version"
	default "0.2.8"

config TINYCRYPT_CTR_PRNG
	bool "PRNG in counter mode"
	default n
	---help---
		This option enables support for the pseudo-random number
		generator in counter mode.

config TINYCRYPT_SHA256
	bool "SHA-256 Hash function support"
	default n
	---help---
		This option enables support for SHA-256
		hash function primitive.

config TINYCRYPT_SHA256_HMAC
