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 3 alternatives - vote for the best!

md5sum is all you need for md5 hashes

Comment by linuxrawkstar 318 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 318 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 318 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.
