Transform a number of bytes pointed by.src in the base32 binary representation in dst

destination memory need to be of correct size, otherwise it will lead to really bad things.

Get the length needed for the destination buffer for a base32 decoding.

if the length is not a multiple of 8, Nothing is returned

convert from base32 in src to binary in dst, using the number of bytes specified

the user should use unBase32Length to compute the correct length, or check that the length specification is proper. no check is done here.
