About Morse Code

The RSA algorithm is a foundational public-key cryptographic system that secures data by using two mathematically linked keys—one public for encryption and one private for decryption. Its strength comes from the difficulty of factoring extremely large composite numbers, a task that becomes computationally impractical as key sizes grow.
By generating a pair of primes and combining them into a modulus, RSA creates a structure where messages can be safely exchanged without sharing secret keys in advance. Today, it underpins secure web communication, digital signatures, and countless authentication systems, remaining a cornerstone of modern encryption despite the rise of newer algorithms.

How it works:

RSA is a public-key encryption system, which means:
You use one key to lock (encrypt) the message → public key
You use another key to unlock (decrypt) the message → private key
These keys are built using three main values:

Symbol Name Purpose
N Modulus Used in both public and private keys
E Public Exponent Used to encrypt
D Private Exponent Used to decrypt

What each value between N, E and D mean:

N: its an product made by two different prime numbers, example: (p * q)
E: its an number between 1 and the product by the primes that made N, meaning that: 1 < E < (p - 1) * (q - 1)
D: it is calculated by (1 (mod (p - 1)(q - 1))) / E
