...table storages that store the same M known malware hashes/signatures. Your data storage should be able to hold up to 10,000 entries. For the hash table, implement two types of hash tables using two different probing approaches for adding and searching for elements in the hash table: one using linear probing, and another using quadratic probing. Use any hashing function with your hash tables, but make sure to justify the selection of the hashing function in your report. Randomly generate M hash values and store one copy of each in the different storage tables. These values will represent the hashes/signatures of known malwares Randomly generate 1000 hash values (N), and search for these values in the storage tables. For each type of storage, plot the running time for the cr...

Hi, you blocked me so im chating threw this. I would like to add feathure that will print nounce for whitch is => difficulty-2. Example: String: Python Difficulty 10: .... hashing.. wow i found hash with difficulty8 ... wow i found 9.. .... hashing... Wooow now i have your desired difficulty 10. Another thing: Your code is calculating "nounce" by som block size. I dont have any.. Is it possible to add nounce only by one ? So i can go threw all numbers and be 100% sure i tried everything.

I'd like some help developing an efficient API that can quickly search through a local folder of images that could potentially be in the thousands, and return a result of closest matches (if there are any). There could be some indexing or hashing needed to build this solution in a way that is optimised enough to not take more than a few seconds to return a result. If that's a one-off process that's done once an image is added to the directory I'd like that to be included as well. The API could be written i Python as it seems most open source libraries for this purpose are in Python. But I'm open to suggestions. It's important that a website can query the API by sending an image through and get matches back in return with a percentage similarity rating,...

Searching for a developer (or a team) who can help me with creating a tool that can: - scan through folders to find files - scan the content of each file and separate each item by a given parameter - save data to MongoDB - generate additional data based on the found items in the files. This can be prepending, appending or hashing of that data. - check for existing data and update if needed Other requirements: - should be a CLI tool - preferred teck stack is MERN, so probably needed to use NodeJs for the CLI tool. Python is also possible - MongoDB is the preferred database - List of plugins that are required - No paid plugins - Clean code - Source code included service The attached file contains more detailed information.

Swift function with completion handler needed to send POST request to API with HMAC authentication. The request body is JSON data. Ideally, developer will use Apple’s CryptoKit for encoding and hashing. Completion handler needs to report if API call is a success or failure. Once code is successfully tested and API call is authenticated, a modified version where variables are sent via querystring instead of in request body is needed. We will be provide API url, AppId and Secret Key for testing.

...CRC-32. The algorithm will be determined by me inside the script I want to be able to determine the original string (plain text) and get the hashed string. To practically understand what I mean, visit the page below. Type a word in the first text field and get the result in the second. HASH SECURITY IS NOT MY CONCERN. That is why I choose CRC hashing instead of other more secure hashing algorithms. My concern is to get a hash which will be shorter than the original text. Example: Original text = This is my text Hashed text = e489ba80 SECOND SCRIPT/UTILITY It will create all possible combinations of the elements that I will determine (uppercase/lowercase letters, numbers, symbols etc). I also wish to determine the number of elements in each combination
