In some cases the name keylen does not reflect the purpose of the variable
anymore once NIST P521 is used but it is the size of the buffer. There-
for, rename keylen to bufsize where appropriate.

why not just "* 8"? using sizeof here makes this function only unreadable.
'unreadable' is a 'strong' word ...
so what is the gain when writing sizeof(u64)?
It matches existing code and a digit is a 'u64'.
