Values :
Public Key Exponent (65537 Generally) = E
PUBLIC key Value = N
PRIVATE key Value = D
FACTOR 1 (prime1) = P
FACTOR 2 (prime2) = Q
(Fonction phi de Euler) INTERMEDIATE value PHI = φ
Ciphertext = C
Calculs :
p and q with N (when N is not that big for factoring attack) = https://factordb.com/
N = p*q
φ(n) = (p - 1) × (q - 1)
d × e ≡ 1 mod φ(n)
M = C^d modulo n
C = M^e modulo n
I have many other tools that I would make presentable for the additions after, such as decryptors with or without padding, a private key setting and others
