Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

Quickly generate an MD5 hash for a text string using OpenSSL

Quickly generate an MD5 hash for a text string using OpenSSL

Thanks to OpenSSL, you can quickly and easily generate MD5 hashes for your passwords.

Alternative (thanks to linuxrawkstar and atoponce):

echo -n 'text to be encrypted' | md5sum -

Note that the above method does not utlise OpenSSL.


There are 2 alternatives - vote for the best!

Terminal - Alternatives
md5sum<<<'text to be encrypted'

Here Strings / A variant of here documents, the format is:

(from bash manpage)

echo -n 'the_password' | md5sum -

Know a better way?

If you can do better, submit your command here.

What others think

echo -n 'text to be encrypted' | md5sum

md5sum is all you need for md5 hashes

Comment by linuxrawkstar 403 weeks and 4 days ago

@linuxrawkstar you should include the '-' at the end for POSIX compliance, even though it works without it.

echo -n 'text to be encrypted' | md5sum -
Comment by atoponce 403 weeks and 4 days ago

True, though I prefer to use OpenSSL, as I know it will/can be present on just about all systems. Even on Windows, I always install OpenSSL. I love consistency. Granted, I could just rename some random Windows utility to md5sum.exe, but that's not fun. I'll add it as an alternative, though.

Comment by Zenexer 403 weeks and 3 days ago

On my Ubuntu system, md5sum

adds a carriage return at the end of the string, the same as using echo without -n :

echo 'text to be encrypted' | openssl md5

So, the original solution with openssl would appear to be the only reliable one.
