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 7 alternatives - vote for the best!

md5sum is all you need for md5 hashes

Comment by linuxrawkstar 349 weeks and 1 day 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 349 weeks and 1 day 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 349 weeks 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.
