Detailed Description

An adapted C++ implementation of the MD4 Message-Digest algorithm.

Since:

3.4

The class usage is the same as KMD5.

Constructor & Destructor Documentation

KMD4::KMD4

(

)

Definition at line 1143 of file kmdcodec.cpp.

KMD4::KMD4	(	const char *	in,
		int	len = -1
	)

Constructor that updates the digest for the given string.

Parameters:

	in	C string or binary data
	len	if negative, calculates the length by using strlen on the first parameter, otherwise it trusts the given length (does not stop on NUL byte).

Definition at line 1148 of file kmdcodec.cpp.

KMD4::KMD4

(

const QByteArray &

a

)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Same as above except it accepts a QByteArray as its argument.

Definition at line 1154 of file kmdcodec.cpp.

KMD4::KMD4

(

const QCString &

a

)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Same as above except it accepts a QCString as its argument.

Member Function Documentation

QCString KMD4::base64Digest

(

)

Returns the value of the calculated message digest in a base64-encoded representation.

Definition at line 1347 of file kmdcodec.cpp.

void KMD4::finalize

(

)

[protected]

finalizes the digest

Definition at line 1253 of file kmdcodec.cpp.

void KMD4::hexDigest

(

QCString &

s

)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Definition at line 1337 of file kmdcodec.cpp.

QCString KMD4::hexDigest

(

)

Returns the value of the calculated message digest in a hexadecimal representation.

Definition at line 1324 of file kmdcodec.cpp.

void KMD4::rawDigest

(

KMD4::Digest &

bin

)

Fills the given array with the binary representation of the message digest.

Use this method if you do not want to worry about making copy of the digest once you obtain it.

Parameters:

bin

an array of 16 characters ( char[16] )

Definition at line 1318 of file kmdcodec.cpp.

const KMD4::Digest & KMD4::rawDigest

(

)

Returns:

the raw representation of the digest

Definition at line 1312 of file kmdcodec.cpp.

void KMD4::reset

(

)

Calling this function will reset the calculated message digest.

Use this method to perform another message digest calculation without recreating the KMD4 object.

Definition at line 1367 of file kmdcodec.cpp.

void KMD4::transform	(	Q_UINT32	buf[4],
		Q_UINT32 const	in[16]
	)			[protected]

Performs the real update work.

Note that length is implied to be 64.

Definition at line 1445 of file kmdcodec.cpp.

bool KMD4::update

(

QIODevice &

file

)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. reads the data from an I/O device, i.e.

from a file (QFile).

NOTE that the file must be open for reading.

Parameters:

file

a pointer to FILE as returned by calls like f{d,re}open

Returns:

false if an error occurred during reading.

Definition at line 1238 of file kmdcodec.cpp.

void KMD4::update

(

const QCString &

in

)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Parameters:

in

message to be added to the digest (QCString).

Definition at line 1171 of file kmdcodec.cpp.

void KMD4::update

(

const QByteArray &

in

)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Parameters:

in

message to be added to the digest (QByteArray).

Definition at line 1166 of file kmdcodec.cpp.

void KMD4::update	(	const unsigned char *	in,
		int	len = -1
	)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Definition at line 1180 of file kmdcodec.cpp.

void KMD4::update	(	const char *	in,
		int	len = -1
	)			[inline]

Updates the message to be digested.

Be sure to add all data before you read the digest. After reading the digest, you can not add more data!

Parameters:

	in	message to be added to digest
	len	the length of the given message.

Definition at line 617 of file kmdcodec.h.

bool KMD4::verify

(

const QCString &

hexdigest

)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Definition at line 1306 of file kmdcodec.cpp.

bool KMD4::verify

(

const KMD4::Digest &

digest

)

returns true if the calculated digest for the given message matches the given one.

Definition at line 1300 of file kmdcodec.cpp.
