How to convert MD5 hash into shadow format?
I am trying to use John the Ripper but it doesn't take regular MD5 hashes, only shadow MD5 hashes. For example this hash: 900150983cd24fb0d6963f7d28e17f72 (which, decrypted, is 'abc') within a text file, John the Ripper does not detect because it is not in shadow format. How can I convert this MD5 hash (and any other MD5 hash) into shadow format?

First off - are you sure that your system uses md5 to hash a password?
Next - is there a salt value?

I do not know if my system uses MD5 for password hashes - the MD5 hash I am testing is just a hash generated by a PHP script I think - I just Googled 'MD5 encrypter' and used one of the links there to create an MD5 hash based on the string I provided; in this case, the string 'abc' (without the single quotes).

No salt value
