xdm linux merge incomplete download parts

 some download stuck at 99.99% , merge them regardless got to ~/.xdm-app-data/Data/*.state cat dec.py import os import re # Define the pattern to extract the segment number pattern = re.compile(r'seg-(\d+)-v1-a1\.ts') # Get the current working directory current_directory = os.getcwd() # List to hold tuples of (segment_number, filename) files_with_segments = [] # Iterate through files in the current directory for filename in os.listdir(current_directory): match = pattern.search(filename) if match: # Extract the segment number as an integer segment_number = int(match.group(1)) # Add the tuple (segment_number, filename) to the list files_with_segments.append((segment_number, filename)) # Sort the list by the segment number (numerical sort) files_with_segments.sort(key=lambda x: x[0]) # Open the filelist.txt for writing with open('filelist.txt', 'w') as filelist: for _, filename in files_with_segments: file...

rsa encryption

 choose two large  prime number p (prime 1) and q (prime 2)   n = p x q , where n is called the modulus for encryption and decryption   φ = ( p - 1) x ( q -1) is called Euler's totient function for n= pq For a given positive integer n, Euler's totient function ϕ(n) is defined as the number of positive integers less than or equal to n that are coprime (i.e., share no common factors) with n. ϕ( n ) = n ∏ p ∣ n ( 1 − 1 p )     \phi(n) = n \prod_{p \mid n} \left(1 - \frac{1}{p}\right)   p ∣ n means that p p divides n , and is a prime factor greater than 1  i  n    example , n=2*3=6 with factors f=1 , 2 , 3 , 4 , 5,6 factors Two numbers are coprime if their greatest common divisor (GCD) is 1 here find gcd(f,n)=1  only 1 and 5 are coprime with 6  φ =1*2 =2   choose e less  than φ , such that  e is co prime with φ , ie  e has no common factor with φ except 1 mathematically : gcd ( e , φ ...
