Once we have \(n\), \(d\) and \(e\), we specify our public key as \((n, e)\) andįor a plain text message \(m\), we can generate the corresponding ciphertext \(c\) Compute \(d\) such that \(ed \equiv 1 (mod \phi)\).Select a number \(e\) that is relatively coprime with \((p -1)\) and \((q - 1)\).Generate two prime numbers \(p, q\) then compute their product \(n\).Generation, key distribution, encryption and decryption) with an illustrativeĮxample using small primes.
In this post, we’ll walk through each step of the RSA algorithm (key
