Digest::RMD160

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..."
