Detailed Description

This class represents the SHA1 wrapper-class.

You can use this class to easily create a sha1 hash. Just create an instance of sha1wrapper and call the inherited memberfunctions getHashFromString() and getHashFromFile() to create a hash based on a string or a file.

Have a look at the following example:

#include <hashlibpp.h>
#include <string>

/*
 * creating a wrapper object
 */
hashwrapper *myWrapper = new sha1wrapper();

/*
 * create a hash from a string
 */
std::string hash1 = myWrapper->getHashFromString("Hello World");

/*
 * create a hash based on a file
 */
std::string hash2 = myWrapper->getHashFromFile("README.TXT");

delete myWrapper;

sha1wrapper implements resetContext(), updateContext() and hashIt() to create a hash.

std::string sha1wrapper::convToString

(

unsigned char *

data

)

[protected, virtual]

This internal member-function convertes the hash-data to a std::string (HEX).

Parameters:

data

The hash-data to covert into HEX

Returns:

the converted data as std::string

Implements hashwrapper.

std::string sha1wrapper::hashIt

(

void

)

[protected, virtual]

This method ends the hash process and returns the hash as string.

Returns:

a hash as std::string

Implements hashwrapper.

void sha1wrapper::updateContext	(	unsigned char *	data,
		unsigned int	len
	)			[protected, virtual]

This method adds the given data to the current hash context.

Parameters:

	data	The data to add to the current context
	len	The length of the data to add

Implements hashwrapper.
