Subject: [PATCH] man3/crypt.3: Correct note on key portion significance
Date: Tue, 11 May 2010 03:35:50 +0200	[thread overview]
Message-ID: <20100511013550.GD16800@machine.or.cz> (raw)
In-Reply-To: <20100418171718.GB25938-9b3RgGIKRfocWVvVuXF20w@public.gmane.org>

As Marcel Moreaux notes:

> The Linux manpage for crypt()[1] contains the following statement as the
> last sentence of the NOTES section:
> 
>     In the SHA implementation the entire key is significant (instead of
>     only the first 8 bytes in MD5).
> 
> It should probably say "DES" where it says "MD5" (and maybe "MD5/SHA"
> where it says "SHA"), because in MD5 password hashing, the entire key is
> significant, not just the first 8 bytes.

This patch fixes the wording.
