Detailed Description

This file contains function for cryptographic hash computation.

Call the MUtils::Hash::create() function to create an instance of the desired hash function. All Hash functions implement the MUtils::Hash::Hash interface.

Function Documentation

create()

MUTILS_API Hash* MUtils::Hash::create	(	const quint16 &	hashId,
		const char *const	key = NULL
	)

Create instance of a hash function.

This function is used to create a new instance of the desired hash function. All Hash functions implement the MUtils::Hash::Hash interface. The caller is responsible for destroying the returned MUtils::Hash::Hash object.

Parameters

hashId	Specifies the desired hash function. This must be a valid hash algorithm identifier, as defined in the Hash.h header file.
key	Specifies on optional key that is used to "seed" the hash function. If a key is given, it must be a NULL-terminated string of appropriate length. If set to NULL, the optional seeding is skipped.

Returns

Returns a pointer to a new MUtils::Hash::Hash object that implements the desired hash function. The function throws if an invalid algorithm identifier was specified!
