hi
i want to generate MD5 hash of string in unix (hp) i have the algorithm which takes file as argument and returns hash of file but when i tried to generate hash of "a" result was "60b725f10c9c85c70d97880dfe8191b3" hash but actually it should have been "0cc175b9c0f1b6a831c399e269772661" now i...

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... (2 Replies)

Hi Guys,
I have a backup program that creates incremental backups and generates a MD5 hash at the same time.
Each server backup has its own sub folder.
Each backup file has a corresponding .md5 file containing a hash and a file name like this.
