char* encode_base64 (char* txt)

Create a base64 coded string of a given char* string.

Documentation

Create a base64 coded string of a given char* string. The result must deleted using release.

Name	Type	Default	Description
Return	char*		New created char* string with the base64 coded input string. Must released using release!
txt	char*	-	any char* string
bufferLength	int	-1	Length of the input buffer. When this parameter is smaller or equal to 0, the length of the input buffer is determined automatically (only works for zero-terminated char* buffers!). When you want to encode binary data, provide the length of the input buffer here.

Encoding the current text and decoding this result must be equal.

Write the content of the current textmodel base64 encoded to a file. After reading and decoding this files boths strings must be equal. Take care to use a big enoug buffer while reading or read and decoded using a loop.
