NAME
oath_base32_decode - API function
SYNOPSIS
#include <oath.h>
oath_base32_decode(3) char * in, size_t inlen, char ** out, size_t
* outlen);
ARGUMENTS
const char * in
input string with base32 encoded data of length inlen
size_t inlen
length of input base32 string in
char ** out pointer to output variable for binary data of length outlen,
or NULL
size_t * outlen
pointer to output variable holding length of out, or NULL
DESCRIPTION
Decode a base32 encoded string into binary data.
Space characters are ignored and pad characters are added if needed.
Non-base32 data are not ignored but instead will lead to an
OATH_INVALID_BASE32 error.
The in parameter should contain inlen bytes of base32 encoded data. The
function allocates a new string in *out to hold the decoded data, and
sets *outlen to the length of the data.
If out is NULL, then *outlen will be set to what would have been the
length of *out on successful encoding.
If the caller is not interested in knowing the length of the output data
out, then outlen may be set to NULL.
It is permitted but useless to have both out and outlen NULL.
RETURNS
On success OATH_OK (zero) is returned, OATH_INVALID_BASE32 is returned if
the input contains non-base32 characters, and OATH_MALLOC_ERROR is
returned on memory allocation errors.
SINCE
1.12.0
