• File sha1.h — part of check-in [5027cbae9b] at 2011-08-26 05:29:43 on branch trunk — Updated to include DoD root CAs as objects in the PKCS#11 module

  Updated to include Netscape Trust Objects (https://developer.mozilla.org/index.php?title=en/NSS/PKCS_%2311_Netscape_Trust) in PKCS#11 module

  Added more attributes to scan for to test driver (user: rkeene, size: 2072) [annotate] [blame] [check-ins using]

/*
 *  sha1.h
 *
 *  Description:
 *      This is the header file for code which implements the Secure
 *      Hashing Algorithm 1 as defined in FIPS PUB 180-1 published
 *      April 17, 1995.
 *
 *      Many of the variable names in this code, especially the
 *      single character names, were used because those were the names
 *      used in the publication.
 *
 *      Please read the file sha1.c for more information.
