CalcFile() [1/2]

static tResult CalcFile ( const cFilename &  strFile, cString &  strDigest  )

static

Utility function to calculate the MD5 digest of an existing file.

Parameters

strFile	[in] The file that the digest should be calculated of.
strDigest	[out] This string wil lbe updated with the hex representation of the 16 byte digest.

Returns

Standard result.

CalcFile() [2/2]

static tResult CalcFile ( const cFilename &  strFile, tUInt8 *  pDigest  )

static

Utility function to calculate the MD5 digest of an existing file.

Parameters

strFile	[in] The file that the digest should be calculated of.
pDigest	[out] A pointer to a 16 byte array that will be filled with the digest.

Returns

Standard result.

CalcString() [1/2]

static tResult CalcString ( const cString &  strInput, cString &  strDigest  )

static

Utility function to calculate the MD5 digest of a string.

Parameters

strInput	[in] The string that the digest should be calculated of.
strDigest	[out] This string wil lbe updated with the hex representation of the 16 byte digest.

Returns

Standard result.

CalcString() [2/2]

static tResult CalcString ( const cString &  strInput, tUInt8 *  pDigest  )

static

Utility function to calculate the MD5 digest of a string.

Parameters

strInput	[in] The string that the digest should be calculated of.
pDigest	[out] A pointer to a 16 byte array that will be filled with the digest.

Returns

Standard result.

Digest() [1/2]

tResult Digest

(

cString &

strDigest

)

Finalizes the computation.

Parameters

strDigest

[out] This string will be updated with the hex representation of the 16 byte digest.

Returns

Standard result.

Digest() [2/2]

tResult Digest

(

tUInt8 *

pDigest

)

Finalizes the computation.

Parameters

pDigest

[out] A pointer to a 16 byte array that will be filled with the digest.

Returns

Standard result.

This method is real-time safe.\nSee @ref page_real_time_safe.\n

Update()

tResult Update	(	const tUInt8 *	pData,
		tUInt32	nSize
	)

Adds new data that should be processed.

Parameters

pData	[in] The data.
nSize	[in] The size of the data.

Return values

ERR_INVALID_STATE

The digest has already been finalized by calling one of the Digest methods.

This method is real-time safe.\nSee @ref page_real_time_safe.\n
