XMLSEC_BASE64_LINESIZE

#define XMLSEC_BASE64_LINESIZE				64

The default maximum base64 encoded line size.

xmlSecBase64CtxCreate ()

xmlSecBase64CtxPtr xmlSecBase64CtxCreate    (int encode,
                                             int columns);

Allocates and initializes new base64 context.

`encode` :	the encode/decode flag (1 - encode, 0 - decode)
`columns` :	the max line length.
Returns :	a pointer to newly created xmlSecBase64Ctx structure or NULL if an error occurs.

xmlSecBase64CtxDestroy ()

void        xmlSecBase64CtxDestroy          (xmlSecBase64CtxPtr ctx);

Destroys base64 context.

ctx :

the pointer to xmlSecBase64Ctx structure.

xmlSecBase64CtxInitialize ()

int         xmlSecBase64CtxInitialize       (xmlSecBase64CtxPtr ctx,
                                             int encode,
                                             int columns);

Initializes new base64 context.

`ctx` :	the pointer to xmlSecBase64Ctx structure,
`encode` :	the encode/decode flag (1 - encode, 0 - decode)
`columns` :	the max line length.
Returns :	0 on success and a negative value otherwise.

xmlSecBase64CtxFinalize ()

void        xmlSecBase64CtxFinalize         (xmlSecBase64CtxPtr ctx);

Frees all the resources allocated by ctx.

ctx :

the pointer to xmlSecBase64Ctx structure,

xmlSecBase64CtxUpdate ()

int         xmlSecBase64CtxUpdate           (xmlSecBase64CtxPtr ctx,
                                             const xmlSecByte *in,
                                             xmlSecSize inSize,
                                             xmlSecByte *out,
                                             xmlSecSize outSize);

Encodes or decodes the next piece of data from input buffer.

`ctx` :	the pointer to xmlSecBase64Ctx structure
`in` :	the input buffer
`inSize` :	the input buffer size
`out` :	the output buffer
`outSize` :	the output buffer size
Returns :	the number of bytes written to output buffer or -1 if an error occurs.

xmlSecBase64CtxFinal ()

int         xmlSecBase64CtxFinal            (xmlSecBase64CtxPtr ctx,
                                             xmlSecByte *out,
                                             xmlSecSize outSize);

Encodes or decodes the last piece of data stored in the context and finalizes the result.

`ctx` :	the pointer to xmlSecBase64Ctx structure
`out` :	the output buffer
`outSize` :	the output buffer size
Returns :	the number of bytes written to output buffer or -1 if an error occurs.

xmlSecBase64Encode ()

xmlChar*    xmlSecBase64Encode              (const xmlSecByte *buf,
                                             xmlSecSize len,
                                             int columns);

Encodes the data from input buffer and allocates the string for the result. The caller is responsible for freeing returned buffer using xmlFree() function.

`buf` :	the input buffer.
`len` :	the input buffer size.
`columns` :	the output max line length (if 0 then no line breaks would be inserted)
Returns :	newly allocated string with base64 encoded data or NULL if an error occurs.

xmlSecBase64Decode ()

int         xmlSecBase64Decode              (const xmlChar *str,
                                             xmlSecByte *buf,
                                             xmlSecSize len);

Decodes input base64 encoded string and puts result into the output buffer.

`str` :	the input buffer with base64 encoded string
`buf` :	the output buffer
`len` :	the output buffer size
Returns :	the number of bytes written to the output buffer or a negative value if an error occurs
