Is there an efficient way to find minimum xor value between a key and elements of a list? Question: Assume that I have a list of 10 thousand random numbers chosen in this way: random_num = list(np.random.choice(2**16, 10000, replace=False)) Now, I have a key in the same range (e.g., 1024), and I need to find …
how to use bitwise operators with binary strings in python Question: so i have binary and i want to XOR every letters, like the example binary from word "maru" : m = 1101101 a = 1100001 XOR = result1 -> get result 1 r = 1110010 XOR = result2 -> result1 will be XOR with …
XOR encryption with a PyObject Question: I’m having trouble encrypting bytes from a PyObject using XOR. For now I only managed to print the bytes as an encoded string (with PyUnicode_AsEncodedString): Here’s what I tried (taken from this SO answer) PyObject* repr = PyObject_Repr(wf.str); // wf.str is a PyObject * PyObject* str = PyUnicode_AsEncodedString(repr, "utf-8", …
XOR linear equation system solver in Python Question: I have n rows and n+1 columns matrix and need to construct such system For example matrix is x4 x3 x2 x1 result 1 1 0 1 0 1 0 1 0 1 0 1 0 1 1 1 0 1 1 0 Then equation will be …
Why compare two strings via calculating xor of their characters? Question: Some time ago I found this function (unfortunately, I don’t remember from where it came from, most likely from some Python framework) that compares two strings and returns a bool value. It’s quite simple to understand what’s going on here. Finding xor between char …
Hamming distance between two strings in Python Question: I need to find the Hamming distance between two strings: chaine1 = 6fb17381822a6ca9b02153d031d5d3da chaine2 = a242eace2c57f7a16e8e872ed2f2287d The XOR function didn’t work, and my search on the web was not very successful. I tried to modify something I found on the web, but there’s some invalid syntax…: assert …
Creating xor checksum of all bytes in hex string In Python Question: While attempting to communicate with an audio processing device called BSS London Blu-80, I discovered I have to send a checksum created by Xoring the message. An example message being sent would be: 0x8d 0x1e 0x19 0x1b 0x83 0x00 0x01 0x01 0x00 0x00 …
django template if or statement Question: Basically to make this quick and simple, I’m looking to run an XOR conditional in django template. Before you ask why don’t I just do it in the code, this isn’t an option. Basically I need to check if a user is in one of two many-to-many objects. req.accepted.all …
Simple Python Challenge: Fastest Bitwise XOR on Data Buffers Question: Challenge: Perform a bitwise XOR on two equal sized buffers. The buffers will be required to be the python str type since this is traditionally the type for data buffers in python. Return the resultant value as a str. Do this as fast as possible. …
