DHT (Distributed Hash Table)

share files without the need for a central server

DHT operates as a peer-to-peer network

magnet:?xt=urn:btih:info_hash&dn=filename&tr=tracker_url

xt stands for "exact topic," and it specifies the type of identifier.

urn:btih: is a standard identifier for BitTorrent info hashes.

info_hash is the unique SHA1 hash of the torrent’s metadata (file structure, file names, etc.), which is the key piece of information needed to find and identify the content.

dn=filename (optional):

dn stands for "display name." This  field specifies the name of the file or content, which is useful for users to identify the torrent.

? separates the base URL from the parameters, and & separates multiple parameters

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 ...
