Hey, A while back I mentioned an app that can, this worked by comparing the of a file, essentially its make up at the byte level. Is there something like windows media center edition for mac. This means, even though two files that are the same size in terms of bits, will be different because of the order of those bits generate a different hash number. This is very useful in comparing different files and ensuring you are working with the right file. All you have to do is compare the hashes of the two files and if they match you are good to go. Today’s post will show you how you generate and hashes in Terminal. Generating MD5 The first stage is to open up Terminal and type the following to generate an MD5 hash.
I managed to get the password hash, but have hit various snags when following guides on decrypting this. Zip utility crashes when trying to open the downloaded 'John the Ripper' utility zip file). Can anyone recommend a hash decrypter? Windows or OS X is fine. Hash a File in Finder “Calculate Hash” feature uses share extension which was brought to modern macOS since macOS 10.10. With this feature, get file hash is only two clicks away.

Md5 Then either type the file name and/or path, or better yet drop the file from Finder into the Terminal window, ensure there is a space after the md5. This will generate an ouput similar to the following: md5 file.png MD5 (file.png) = 251b5c95860dca0b07b15e927fc0cc84 Very simple. Generating SHA-1 Now, there is a better hash function called SHA-1, that produces a more accurate hash of the file you are wanting to check. To generate an SHA-1 file you need to use, which should be installed on your Mac by default. To generate an SHA-1 hash type in the following, followed by the path to the file, or the file dropped onto the Finder window: openssl sha1 For example: openssl sha1 file.png SHA1(file.png)= ba45256be13be6dc5dfbe381c1c3be Notice the longer number, you can use openssl for md5, just enter md5 instead of sha1. This tip is very useful if you want to compare the hashes of the files you have downloaded from the Apple downloads page, for example has a hash at the bottom which you can compare to the one you have created for the file on your computer.
Multiple Files If you want to generate hashes for multiple files, its really simple. The best method is to use Finder and openssl. In Finder type the command you want for the hash function you want to run (eg openssl sha1) and then drop all of the files you want to generate hashes for on to the Terminal window from Finder. Terminal will run through each file and output the hash function.
OS X 10.5 (Leopard) + OS X 10.6 (Snow Leopard) First find a users' GUID: dscl localhost -read /Search/Users/username| grep GeneratedUID| cut -c15- After getting the GUID you can dump various hashes. By default the only hash stored is the salted SHA1. If the user has turned on SMB file sharing then the NTLM hash will also be stored. If you upgraded from 10.3->10.4->10.5 then the zero salted SHA1 is also stored. Salted SHA1 (first 8 characters are the salt) cat /var/db/shadow/hash/GUID| cut -c105-152 Zero-Salted SHA1 (first 8 characters are the salt and will always be all zeros) cat /var/db/shadow/hash/GUID| cut -c169-216 NTLM (first 32 characters are NT, next 32 are LM) cat /var/db/shadow/hash/GUID| cut -c-64. OS X 10.8 (Mountain) & 10.9 (Mavericks) & 10.10 (Yosemite) The shadow files are stored on the filesystem at /var/db/dslocal/nodes/Default/users/%user%.plist.
They are in plist format so you'll need to use the plutil command to view them or use the defaults command to extract/write specific keys if desired. Only the root user has access to the files. To view the contents of a shadow file for a user: sudo plutil -p /var/db/dslocal/nodes/Default/users/%username%.plist To get the hash: sudo defaults read /var/db/dslocal/nodes/Default/users/%username%.plist ShadowHashData|tr -dc 0-9a-f|xxd -r -p|plutil -convert xml1 - -o - Where%username% in the above example is the user you're looking for the hash for. Finally the wanted hash starts with '$ml$' and length is 203 characters.
