byteReverse()

void XrdCksCalcmd5::byteReverse ( unsigned char *  buf, unsigned  longs  )

private

Current()

char * XrdCksCalcmd5::Current ( )

inlinevirtual

Get the current binary checksum value (defaults to final). However, the final checksum result is not affected.

Returns

the checksum value in binary format. The pointer to the value becomes invalid once the associated object is deleted.

Reimplemented from XrdCksCalc.

References Final(), and myContext.

Final()

char * XrdCksCalcmd5::Final ( )

virtual

Get the actual checksum in binary format.

Returns

the checksum value in binary format. The pointer to the value becomes invalid once the associated object is deleted.

Implements XrdCksCalc.

Referenced by Current().

Init()

void XrdCksCalcmd5::Init ( )

virtual

Initializes data structures (must be called by constructor). This is always called to reuse the object for a new checksum.

Implements XrdCksCalc.

Referenced by XrdCksCalcmd5().

MD5Transform()

void XrdCksCalcmd5::MD5Transform ( unsigned int  buf[4], unsigned int const  in[16]  )

private

MD5Update()

void XrdCksCalcmd5::MD5Update ( unsigned char const *  buf, unsigned int  len  )

private

Referenced by Update().

New()

XrdCksCalc * XrdCksCalcmd5::New ( )

inlinevirtual

Get a new instance of the underlying checksum calculation object.

Returns

the checksum calculation object.

Implements XrdCksCalc.

References XrdCksCalcmd5().

Type()

const char * XrdCksCalcmd5::Type ( int &  csSize )

inlinevirtual

Get the checksum object algorithm name and the number bytes (i.e. size) required for the checksum value.

Parameters

csSize

-> Parameter to hold the size of the checksum value.

Returns

the checksum algorithm's name. The name persists event after the checksum object is deleted.

Implements XrdCksCalc.

References myDigest.

Update()

void XrdCksCalcmd5::Update ( const char *  Buff, int  BLen  )

inlinevirtual

Compute a running checksum. This method may be called repeatedly for data segments; with Final() returning the full checksum.

Parameters

Buff	-> Data to be checksummed.
BLen	-> Length of the data in Buff.

Implements XrdCksCalc.

References MD5Update().
