“.. I’m leaving this campus today. I will miss the late-night hangouts with Kartik and Pankaj.. I will miss the stay in Kartik’s room with Arjun and Rohit (If you are reading this, All the best for your IAS, brother). I will miss Ramnath, Arnab and all my friends here and this great institution.. I’m sure I will be back here for the next event.. With a million beautiful memories in 4 days.. Adieu NITC..”
Hi, Here’s a small anagram solver written in C. It works based on generating permutations of given string and comparing them using a dictionary. For fast search in dictionary, the program first creates an index of the starting location of each alphabet. It takes a few minutes to process long words.
Here’s the source code. Suggestions are always welcome, Greetings
Update: There’s a little problem in using the term ‘anagram solver’ here. An anagram solver finds words from another valid word – But this program finds words from the characters of given valid/invalid word. Thanks to technikhil for the info
Yesterday, I went to MES College of Engineering to deliver a small talk on programming and free software, it was entirely a new experience for me. A bigger crowd than expected was present. It went fine Thanks to Raghesh sir, Raju sir, S@IT and to friends there
I’m happy to share my little slides. It was created according to numerous suggestions by Raghesh sir. For fun, the presentation was started with a SMS trigger from audience The code for that is like ‘get-thing-done’ and doesn’t have the quality to upload. It’s developed using python with gammu module. Please feel free to tell me if you want to have a look at the code.
Attribution: ‘Input -> Fun -> Output’ is an idea got from Niyam Bhushan during his talk at NIT Calicut on FOSS Meet day.
Here’s a small encryption/decryption tool that works based on AES algorithm. No matter how weak your password is, the program converts it to a 32 digits hexadecimal number before encrypting. This is achieved by finding the MD5 hash of the password using hashlib python module. This hash is used to encrypt the file.
The idea in my mind while writing this program was this:
Suppose a cracker gets an encrypted file and he figures out it’s encrypted using AES somehow. Then he starts brute force attack on it to find the key and extract information. If the password used to encrypt that file is weak and if it’s based on a dictionary word, the cracker can easily figure out the password. Hence the password given by the user must be made stronger by the encrypting program. And the best way to make a password strong is by using digest algorithms since it’s unique to a string.
What do you think? Am I wrong? Thank you
Wrote a small python script that can be used with your favorite text editor as a simple note taking application. Hope you like it, suggestions are always welcome
