* Document-class: Digest::RMD160 < Digest::Base
|
|
* A class for calculating message digests using RIPEMD-160
|
|
* cryptographic hash function, designed by Hans Dobbertin, Antoon
|
|
* Bosselaers, and Bart Preneel.
|
|
*
|
|
* RMD160 calculates a digest of 160 bits (20 bytes).
|
|
*
|
|
* == Examples
|
|
* require 'digest'
|
|
*
|
|
* # Compute a complete digest
|
|
* Digest::RMD160.hexdigest 'abc' #=> "8eb208f7..."
|
|
*
|
|
* # Compute digest by chunks
|
|
* rmd160 = Digest::RMD160.new # =>#<Digest::RMD160>
|
|
* rmd160.update "ab"
|
|
* rmd160 << "c" # alias for #update
|
|
* rmd160.hexdigest # => "8eb208f7..."
|
|
*
|
|
* # Use the same object to compute another digest
|
|
* rmd160.reset
|
|
* rmd160 << "message"
|
|
* rmd160.hexdigest # => "1dddbe1b..."
