For given n and e, there is unique number d. Number d is the inverse of e modulo (p - 1)(q – 1). This means that d is the number less than (p - 1)(q - 1) such that when multiplied by e, it is equal to 1 modulo (p - 1)(q - 1). How do I find D in RSA? In your example you cannot take e = 11 because e must be 0 < e < ϕ ( n) with ϕ ( n) = ( p − 1) ( q − 1). Let's take the example of p = 3 and q = 11 then n = 33 and ϕ ( n) = 2 ∗ 10 = 20. We take e = 3 then we calculate d so that e*d = 1 mod n in this case d=7 because 3*7 = 21 = 1 mod 20 Raymond KipOur 24/7 Technical Support and Customer Success teams will help you realize faster time-to-value, reduce total cost of ownership, and provide personalized support tailored to your needs.

RSA used without padding may have some problems: The values m = 0 or m = 1 always produce ciphertexts equal to 0 or 1 respectively, due to the properties of exponentiation. When encrypting with small encryption exponents (e.g., e = 3) and small values of the m, the (non-modular) result of may be strictly less than the modulus n. This is strength of RSA. Generate the private key. Private Key d is calculated from p, q, and e. For given n and e, there is unique number d. Number d is the inverse of e modulo (p - 1)(q - 1). This means that d is the number less than (p - 1)(q - 1) such that when multiplied by e, it is equal to 1 modulo (p - 1)(q - 1).For the RSA signatures, the most adopted standard is "PKCS#1", which has several versions (1.5, 2.0, 2.1, 2.2), the latest described in RFC 8017.
