Detailed Description

Encode binary data using printable characters.

Function Documentation

Base64 convert string.

Parameters

[in]	s	Input string
[in]	out_size	The size of the buffer that 'out' pointing to , make sure it's large enough
[out]	out	Output string

Returns: If successful return the length of string,else return 0
char *str = "aGVsbG8gd29ybGQ=" ;

int len = getDeBase64Size ( str ) ;

char *out = (char *)malloc( len ) ;

memset( out, 0, len ) ;

base64Decode( str, out, len ) ;

printf( "out is: %s\n", out ) ;

free( out ) ;
