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..."
