final()

std::array< uint8_t, 32 > llvm::SHA256::final

(

)

Return the current raw 256-bits SHA256 for the digested data since the last call to init().

This call will add data to the internal state and as such is not suited for getting an intermediate result (see result()).

hash()

std::array< uint8_t, 32 > llvm::SHA256::hash ( ArrayRef< uint8_t > Data )

static

Returns a raw 256-bit SHA256 hash for the given data.

References llvm::Data, final(), SHA256(), and update().

init()

void llvm::SHA256::init

(

)

Reinitialize the internal state.

result()

std::array< uint8_t, 32 > llvm::SHA256::result

(

)

Return the current raw 256-bits SHA256 for the digested data since the last call to init().

This is suitable for getting the SHA256 at any time without invalidating the internal state so that more calls can be made into update.
