oath_base32_decode: API function
NAMEoath_base32_decode - API function
- 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
DESCRIPTIONDecode 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.
RETURNSOn 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.
