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.

Constructor & Destructor Documentation

◆ ESha1Hasher() [1/2]

eVision.ESha1Hasher.ESha1Hasher ( )

Constructs a ESha1Hasher object.

◆ ESha1Hasher() [2/2]

eVision.ESha1Hasher.ESha1Hasher ( eVision.ESha1Hasher other )

Member Function Documentation

◆ Final()

void eVision.ESha1Hasher.Final ( )

Finalize the computation of the SHA-1 hash value.

◆ Get32BitHash()

void eVision.ESha1Hasher.Get32BitHash ( IntPtr result )

Gets the hash value as a 32-bits interger.

◆ GetHash() [1/2]

string eVision.ESha1Hasher.GetHash ( )

Gets an hexadecimal representation of the hash.

◆ GetHash() [2/2]

void eVision.ESha1Hasher.GetHash ( IntPtr uDest )

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

◆ HashBuffer()

string eVision.ESha1Hasher.HashBuffer ( eVision.EBaseROI roi )

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

◆ HashObject()

string eVision.ESha1Hasher.HashObject ( 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.

◆ Reset()

void eVision.ESha1Hasher.Reset ( )

◆ Update()

void eVision.ESha1Hasher.Update	(	IntPtr	data,
		uint	len )

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