Detailed Description

Object for computing a SHA-1 hash.

In order to compute a SHA-1 hash, one must call ESha1Hasher::Update with the data to hash and then call ESha1Hasher::Final to finalize the SHA-1 hash computation.

If the data comes in chunks (network packets, filesystem read, etc.), you can call ESha1Hasher::Update for each of your chunks.

uDest

)

const

Gets the full hash value as a uint8_t array of size 20 (160bits).

HashBuffer()

std::string eVision::ESha1Hasher::HashBuffer

(

const eVision::EBaseROI &

roi

)

Hash of the data buffer of the given eVision image object.

HashObject()

std::string eVision::ESha1Hasher::HashObject

(

const eVision::EBaseROI &

roi

)

Hash of the given eVision image object including its internal data buffer.

The hash function work by serializing the object into a EMemorySerializer.

)

Update()

void eVision::ESha1Hasher::Update	(	void *	data,
		uint32_t	len )

Updates the current SHA-1 hash with the given data of given length.
