Description Erinn Looney-Triggs 2012-01-02 09:24:33 UTC 
Description of problem:
RHEA-2011:0633 enhanced grub to allow the use of SHA based password hashes, however there is no documentation for the use of this, nor even is the bug that is referenced open to the public.
Comment 3 Vladimir Serbinenko 2012-08-01 17:57:43 UTC 
It's documented in manual. Namely in the chapter "Invoking grub-crypt".
Comment 4 Erinn Looney-Triggs 2012-08-01 18:17:37 UTC 
Not to be a pain but can you please give me a link for that, because all I am finding in "Invoking grub-md5-crypt" which as the name implies doesn't cover the SHA part of this.

Comment 5 Vladimir Serbinenko 2012-08-01 18:44:59 UTC 
From the Fedora/RHEL patch for sha:

+@item --md5
+Use MD5 for password encryption.
+@item --sha-256
+Use SHA-256 for password encryption.
+@item --sha-512
+Use SHA-512 for password encryption. This is the default.
+@end table
