The post on elliptic curves received negative feedback for its lack of depth and clarity regarding Elliptic Curve Cryptography (ECC). Users criticized the explanation for failing to include practical examples and the essential concepts behind ECC's security, such as finite fields. The discussion highlighted the complexity of elliptic curves with equations like y² = x³ + bx + c, which may not be intuitive for beginners. Furthermore, users noted that the article’s examples used unrealistic encryption demonstrations, diminishing its educational value. Outside links were provided suggesting more thorough resources. The conversation hinted at the debate around the efficiency of ECC compared to traditional methods like RSA, especially in low-resource devices, but many commenters felt unsatisfied with the material presented.
