Hash of files an strings with Ruby using MD5 and SHA256

digest.rb

require 'digest'

# Get SHA256 Hash of a file
puts Digest::SHA256.hexdigest File.read "data.dat"
# Get MD5 Hash of a file
puts Digest::MD5.hexdigest File.read "data.dat"
# Get MD5 Hash of a string
puts Digest::SHA256.hexdigest "Hello World"

# Get SHA256 Hash of a string using update
sha256 = Digest::SHA256.new
sha256.update "Hello"
sha256.update " World"
puts sha256.hexdigest

Copy paste error on line 7 buddy 😄 but thanks for the example!

also for md5 a file: Digest::MD5.file('filename').hexdigest

cool

Thanks,
