MD5 hashing in CoffeeScript, Perl and Scala

Kind of a follow up to my on MD5 hashing in Python, Ruby and Groovy posting, Here is a way of doing MD5 hashing in CoffeeScript and Perl.

CoffeeScript/Node.js⌗

	crypto = require('crypto');

	#Quick MD5 of text
	text = "MD5 this text!"
	md5hash1 = crypto.createHash('md5').update(text).digest("hex")

	#MD5 of text with updates
	m = crypto.createHash('md5')
	m.update("MD5 ")
	m.update("this ")
	m.update("text!")
	md5hash2 = m.digest("hex")

	#Output
	console.log "#{md5hash1} should be the same as #{md5hash2}"

	use Digest::MD5 qw(md5 md5_hex md5_base64);

	#Quick MD5 of text
	my $text = "MD5 this text!";
	my $md5hash1 = md5_hex( $text );

	#MD5 of text with updates
	$md5 = Digest::MD5->new;
	$md5->add("MD5 ");
	$md5->add("this ");
	$md5->add("text!");
	$md5hash2 = $md5->hexdigest;

	#Output
	print "$md5hash1 should be the same as $md5hash2\n";

	import java.security.MessageDigest

	val digest = MessageDigest.getInstance("MD5")

	//Quick MD5 of text
	val text = "MD5 this text!"
	val md5hash1 = digest.digest(text.getBytes).map("%02x".format(_)).mkString

	//MD5 of text with updates
	digest.update("MD5 ".getBytes())
	digest.update("this ".getBytes())
	digest.update("text!".getBytes())
	val md5hash2 = digest.digest().map(0xFF & _).map("%02x".format(_)).mkString

	//Output
	println(md5hash1 + " should be the same as " + md5hash2)

I also moved the code for Python, Ruby and Groovy into the same Gist on Github. If you know a better way feel free to fork and update!
