Rsa public key formula

The RSA algorithm involves four steps: key generation, key distribution, encryption, and decryption. A basic principle behind RSA is the observation that it is practical to find three very large positive integers e, d, and n, such that with modular exponentiation for all integers m (with 0 ≤ m < n): and that knowing e and n, or even m, it can be extremely difficult to find d. The triple bar (≡) here denotes modular congruence (which is to say that when you divide (m ) by n and m by n, they bot… WebFeb 27, 2016 · A RSA public key consists in two integers, the modulus ( n) and the public exponent ( e ). It is normally encoded as an ASN.1 structure that is a SEQUENCE of two INTEGER values.

WebWikipedia about RSA key generation: Determine d as: d = e − 1 mod ϕ ( n) i.e., d is the multiplicative inverse of e mod ϕ ( n). This is more clearly stated as solve for d given ( d e) = 1 mod ϕ ( n) This is often computed using the extended Euclidean algorithm. d is kept as the private key exponent. The public key is represented by the integers n and e, and the private key by the integer d (although n is also used during the decryption process, so it might be considered to be a part of the private key too). m represents the message (previously prepared with a certain technique explained below).
