Decode a Base64-encoded string and return decoded contents in a buffer.
See the wxBase64Decode(void*,size_t,const char*,size_t,wxBase64DecodeMode,size_t*) overload for more information about the parameters of this function. The difference of this overload is that it allocates a buffer of necessary size on its own and returns it, freeing you from the need to do it manually. Because of this, it is simpler to use and is recommended for normal use.
Include file:
#include <wx/base64.h>
wxMemoryBuffer wxBase64Decode | ( | const wxString & | src, |
wxBase64DecodeMode | mode = wxBase64DecodeMode_Strict , |
||
size_t * | posErr = NULL |
||
) |
Decode a Base64-encoded wxString and return decoded contents in a buffer.
See the wxBase64Decode(void*,size_t,const char*,size_t,wxBase64DecodeMode,size_t*) overload for more information about the parameters of this function.
This overload takes as input a wxString and returns the internally-allocated memory as a wxMemoryBuffer, containing the Base64-decoded data.
Include file:
#include <wx/base64.h>

) |
This function decodes a Base64-encoded string.
This overload is a raw decoding function and decodes the data into the provided buffer dst of the given size dstLen. An error is returned if the buffer is not large enough – that is not at least wxBase64DecodedSize(srcLen) bytes. Notice that the buffer will not be NULL-terminated.
This overload returns the number of bytes written to the buffer or the necessary buffer size if dst was NULL or wxCONV_FAILED
on error, e.g. if the output buffer is too small or invalid characters were encountered in the input string.
dst | Pointer to output buffer, may be NULL to just compute the necessary buffer size. |
dstLen | The size of the output buffer, ignored if dst is NULL. |
src | The input string, must not be NULL. For the version using wxString, the input string should contain only ASCII characters. |
srcLen | The length of the input string or special value wxNO_LEN if the string is NULL-terminated and the length should be computed by this function itself. |
mode | This parameter specifies the function behaviour when invalid characters are encountered in input. By default, any such character stops the decoding with error. If the mode is wxBase64DecodeMode_SkipWS, then the white space characters are silently skipped instead. And if it is wxBase64DecodeMode_Relaxed, then all invalid characters are skipped. |
posErr | If this pointer is non-NULL and an error occurs during decoding, it is filled with the index of the invalid character. |

) |
Decode a Base64-encoded wxString.
See the wxBase64Decode(void*,size_t,const char*,size_t,wxBase64DecodeMode,size_t*) overload for more information about the parameters of this function, the only difference between it and this one is that a wxString is used instead of a char*
pointer and its length.
Include file:
#include <wx/base64.h>
size_t wxBase64DecodedSize | ( | size_t | srcLen | ) |
Returns the size of the buffer necessary to contain the data encoded in a base64 string of length srcLen.
This can be useful for allocating a buffer to be passed to wxBase64Decode().
Include file:

size_t wxBase64Encode | ( | char * | dst, |
size_t | dstLen, | ||
const void * | src, | ||
size_t | srcLen | ||
) |
This function encodes the given data using base64.
To allocate the buffer of the correct size, use wxBase64EncodedSize() or call this function with dst set to NULL – it will then return the necessary buffer size.
This raw encoding function overload writes the output string into the provided buffer; the other overloads return it as a wxString.
dst | The output buffer, may be NULL to retrieve the needed buffer size. |
dstLen | The output buffer size, ignored if dst is NULL. |
src | The input buffer, must not be NULL. |
srcLen | The length of the input data. |
