Decode(const TDesC8 &, TDes8 &)

IMPORT_C TBool	Decode	(	const TDesC8 &	aSrcString,
			TDes8 &	rDestString
		)

Decodes the Base64 string to ASCII pattern.

Parameters

const TDesC8 & aSrcString	The source string in Base64 codeset.
TDes8 & rDestString	The destination string with converted ASCII code values.

Encode(const TDesC8 &, TDes8 &)

IMPORT_C TInt	Encode	(	const TDesC8 &	aSrcString,
			TDes8 &	rDestString
		)

Encodes an ASCII string to Base64 string.

Parameters

const TDesC8 & aSrcString	The source string in ASCII code.
TDes8 & rDestString	The destination string with converted base64 values.

PortableEncode(const TDesC8 &, TDes8 &, TInt)

IMPORT_C TInt	PortableEncode	(	const TDesC8 &	aSrcString,
			TDes8 &	aDestString,
			TInt	aLineLength = -1
		)

Encodes an ASCII string to Base64 string.

Parameters

const TDesC8 & aSrcString	The source string in ASCII.
TDes8 & aDestString	The destination string with converted base64 values.
TInt aLineLength = -1	The maximum line length of the encoded base64 values. A CR/LF sequence will be added after these many characters. The default value is -1, which means no CR/LF is added to output. The encoding is compliant with RFC 4648
