"WebIf the order of a curve defined over a field F p is equal to p, then that means the curve is anomalous, and there's an attack (called Smart's attack) that we can apply to solve the discrete log easily. So we can apply this to the curve defined over F p. This also implies that every point generated by the curve also has an order of p. " - Cryptohack elliptic curves

WebDescription It is essential that keys in symmetric-key algorithms are random bytes, instead of passwords or other predictable data. The random bytes should be generated using a cryptographically-secure pseudorandom number generator (CSPRNG). WebThe use of elliptic curves for public-key cryptography was first suggested in 1985. After resisting decades of attacks, they started to see widespread use from around 2005, …
