\Description
|
|
This module implements SHA1 as defined in RFC 3174.
|
|
|
|
\Copyright
|
|
Copyright (c) Electronic Arts 2004. ALL RIGHTS RESERVED.
|
|
|
|
\Notes
|
|
The implementation is based on the algorithm description in sections
|
|
3 through 6 of RFC 3174 and not on the C code in section 7.
|
|
|
|
The code deliberately uses some of the naming conventions from
|
|
the RFC to in order to aid comprehension.
|
|
|
|
This implementation is limited to hashing no more than 2^32-9 bytes.
|
|
It will silently produce the wrong result if an attempt is made to
|
|
hash more data.
