How To Use Openssl For Md5sum On Mac

Okay, since I plan to upload old backup archives to the cloud with fear to lose data integrity, I wanted to calculate the MD5 hash of these archives before any manipulation. OSX has natively the MD5 command provided by OpenSSL but no argument to check automatically a file checksum against another file which would contain its checksum. And the -r generates broken MD5SUMS pattern output (the default OpenSSL star is stripped)! In order to be able to use the md5sum command on OSX like on other Unix platforms, I developped a small script that will behave alike. I and it's Open Source so you're free to contribute. Why you shouldn't use the OSX native md5 command? Mac os x mavericks iso download for virtualbox linux. By default, the md5sum command (which is a shortcut to OpenSSL MD5 digest command I guess) ouputs the following pattern:.

The md5sum command commonly uses the star as filename delimiter (or the space if no star.). Mac g5 specs. I don't know how it's coded behind but I got it wrong with the OSX md5 -r command. This command strips the star. Give it a try: # Creates a dumbass file dd if=/dev/random of=./file bs=1m count=1 # Gets file MD5 sum with md5 command md5 -r file 99a31dec4c3b780e220c4b80f0f41f6a file # Gets file MD5 sum with OpenSSL command openssl dgst -md5 -r file 99a31dec4c3b780e220c4b80f0f41f6a *file # Counts output characters following the md5 command md5 -r file wc -c 38 # Counts output characters following the OpenSSL command openssl dgst -md5 -r file wc -c 39 Joris Berthelot.

My quick poke at the --help for md5sum demonstrates that the command: md5sum - will then give a prompt for simple input. Inputting some text and then using Enter and then Ctrl+ D to signify end of file then causes md5sum to spit out the MD5 of the raw text you entered (including that Enter, it's a CR, IIRC). Less to type and no piping! And avoiding your plaintext password being recorded in shell history! Image maker for mac.

If you do not want that trailing CR (which is usually the case if you want to hash a password), don't hit Enter before Ctrl+ D, enter Ctrl+ D twice instead. In my scripts I found that there are 2 things that you should know about this issue. • It does not matter if you do echo '$myvariable' or echo -n '$myvariable' but you should always use the doubleqoutes for strings and always use the same method. If not things won't match.

• in the output you get always a trailing space and a dash as shown in the example: $ echo -n Welcome md5sum 7803ffcaea43bb81a439fde13b29bc35 - to get rid of that and stay only with the code 7803ffcaea43bb81a439fde13b29bc35, do: echo '$myvariable' md5sum cut -d' ' -f1.

I'm using MacOS X 10.7.5 and I need a newer OpenSSL version due to. There are several tutorials on the internet and I tried the following: brew install openssl brew link openssl --force Nevertheless, it does not work: openssl version OpenSSL 0.9.8r 8 Feb 2011 brew unlink openssl && brew link openssl --force Unlinking /usr/local/Cellar/openssl/1.0.1e. 1139 links removed Linking /usr/local/Cellar/openssl/1.0.1e. 1139 symlinks created The SVN issue is not resolved either.

I would rather not try the MacPorts way because it may interfere with Homebrew. Installed openssl on mac with brew but nothing found on /usr/local/bin where other brew installed bins are located. Found my fresh openssl here: /usr/local/opt/openssl/bin/openssl Run it like this: /usr/local/opt/openssl/bin/openssl version I don't want to update OS X openssl, while some OS stuff or other 3rd party apps may have dependency on older version. I also don't mind longer path than just openssl Writing this here for all the Googlers who are looking for location of openssl installed by brew. I had this issue and found that the installation of the newer openssl did actually work, but my PATH was setup incorrectly for it -- my $PATH had the ports path placed before my brew path so it always found the older version of openssl.
