Hi --
I have version 3.23 of man-pages (Fedora 13). At the very
end of 'Glibc Notes' of crypt(3):
In the SHA implementation the entire key is significant
(instead of only the first 8 bytes in MD5).
I'm pretty sure that's incorrect. I think both MD5 and SHA implementations
use the whole key, and the 8-byte significance restriction is
applies to (just) the original DES.
I also have version 2.39 of man-pages on Red Hat 5; I think it's more
accurate there.
The problem is also present on the online man page:
http://www.kernel.org/doc/man-pages/online/pages/man3/crypt.3.html
The man page also may be incorrect with the max salt lengths.
I think this is eight bytes for MD5, 16 for SHA-256 and SHA-512.
(The page implies 16 for MD5 too.)
Thanks much for your work on the man pages.
