Branch: MAIN
CVS Tags: OPENBSD_6_0_BASE, OPENBSD_6_0, OPENBSD_5_9_BASE, OPENBSD_5_9, OPENBSD_5_8_BASE, OPENBSD_5_8, OPENBSD_5_7_BASE, OPENBSD_5_7, OPENBSD_5_6_BASE, OPENBSD_5_6, OPENBSD_5_5_BASE, OPENBSD_5_5, OPENBSD_5_4_BASE, OPENBSD_5_4 Changes since 1.8: +22 -2 lines
SHA-224 is to SHA-256 as SHA-384 is to SHA-512. It was added in a
later revision of FIPS-180. OK miod@ jmc@ guenther@ djm@
