md5sum.rb

This Ruby code snippet demonstrates the use of the Digest::MD5 module for calculating MD5 hash values.

• It first requires the digest/md5 library.
• Digest::MD5.hexdigest("ruby") calculates the MD5 hash of the string “ruby” and returns it as a hexadecimal string (“58e53d1324eef6265fdb97b08ed9aadf”).
• Digest::MD5.file('input/digest/md5sum.rb').to_s calculates the MD5 hash of the contents of the file ‘input/digest/md5sum.rb’ and returns it as a hexadecimal string (“b9e992f67fcc4e238d9964a07aba6dd7”).

Ruby code snippet

require 'digest/md5'
#=> true

Digest::MD5.hexdigest("ruby")
#=> "58e53d1324eef6265fdb97b08ed9aadf"

Digest::MD5.file('input/digest/md5sum.rb').to_s
#=> "b9e992f67fcc4e238d9964a07aba6dd7"
