The SSL Protocol Version 3.0, 18-Nov-96 states that the padding for a MAC
write key is as follows (sorry I can' provide the section):

For MD5, the MAC write key is 16 bytes (the size of the hash). It is padded
with 48 bytes of a known byte sequence to produce 64 bytes of salt.

For SHA, the MAC write key is 20 bytes (the size of the hash). The spec that
I am reading says that it is to be padded with _40_ bytes of a known byte
sequence to produce 60 bytes of salt. Why isn't the MAC write key for SHA
padded with 44 bytes?

Thanks in advance.
