/*
* Document-class: Digest::SHA1 < Digest::Base
* A class for calculating message digests using the SHA-1 Secure Hash
* Algorithm by NIST (the US' National Institute of Standards and
* Technology), described in FIPS PUB 180-1.
*
* See Digest::Instance for digest API.
*
* SHA-1 calculates a digest of 160 bits (20 bytes).
*
* == Examples
* require 'digest'
*
* # Compute a complete digest
* Digest::SHA1.hexdigest 'abc' #=> "a9993e36..."
*
* # Compute digest by chunks
* sha1 = Digest::SHA1.new # =>#<Digest::SHA1>
* sha1.update "ab"
* sha1 << "c" # alias for #update
* sha1.hexdigest # => "a9993e36..."
*
* # Use the same object to compute another digest
* sha1.reset
* sha1 << "message"
* sha1.hexdigest # => "6f9b9af3..."
