|
* 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..."
