length of SHA1 hash in bytes

Function Documentation

VTM_API int vtm_crypto_sha1	(	const void *	in,
		size_t	len,
		void *	buf,
		size_t	buf_len
	)

Builts the SHA1 hash over a given memory region.

Parameters

in	pointer to start of memory region
len	the size of the memory region
buf	pointer to buffer where hash will be written to
buf_len	size of supplied buffer

Returns

VTM_OK if the hash was calculated successfully

VTM_E_INVALID_ARG if one of the arguments was not valid, for example if a too small buffer was supplied

VTM_ERROR if the hash could not be calculated
