Cryptographic quine variant

Question

Create a program that prints the MD5 sum of its source in the form:

MD5 sum of my source is: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

No cheating - you can't just read the source file and compute its sum. The program must not read any external information.

Of course you can use a MD5 library available for your language.

Python 157 149

r='r=%r;import md5;print "MD5 sum of my source is: "+md5.new(r%%r).hexdigest()';import md5;print "MD5 sum of my source is: "+md5.new(r%r).hexdigest()

MD5 sum of my source is: bb74dfc895c13ab991c4336e75865426

	I'm getting a different md5sum for the source file. – slackwear Nov 9 '12 at 13:38
	@slackwear what are you getting? – Matt Nov 9 '12 at 13:39
	oh you've edited it again. Right now I get `24ba0a79636297dab8803f571d4e3b44 md.py` using md5sum in linux – slackwear Nov 9 '12 at 13:43
	@slackwear it looks like you have an extra newline at the end of your source file – Matt Nov 9 '12 at 13:48
	I've tried it with and without a trailing newline...maybe i'm missing something here – slackwear Nov 9 '12 at 13:50
