Two words are worth noting here in "ECDSA" and that's "Curve" and "Algorithm" because it means that ECDSA is basically all about mathematics.. so I think it’s important to start by saying : “hey kids, don’t slack off at school, listen to your teachers, that stuff might be usefu...
ECDSA是Elliptic Curve Digital Signature Algorithm【椭圆曲线数字签名算法】的简称,主要用于对数据(比如一个文件)创建数字签名,以便于你在不破坏它的安全性的前提下对它的真实性进行验证。可以将它想象成一个实际的签名,你可以识别部分人的签名,但是你无法在别人不知道的情况下伪造它。而ECDSA签名和真实签名的区别在于...

publicSystem.Security.Cryptography.CngAlgorithm HashAlgorithm {get;set; } 屬性值 CngAlgorithm 指定雜湊演算法的物件。 例外狀況 ArgumentNullException 值為null。 備註 此屬性接受下列演算法:MD5、Sha1、Sha256、Sha384、 和Sha512。 也可以使用其他自定義哈希演算法。
publicvirtualbyte[]SignData(byte[] data, System.Security.Cryptography.HashAlgorithmName hashAlgorithm); 参数 data Byte[] 要为其计算哈希的输入数据。 hashAlgorithm HashAlgorithmName 要用于创建哈希值的哈希算法。 返回 Byte[] 指定数据的 ECDSA 签名。

In addition to its support for various elliptic curves, CryptOne’s prowess extends to the widely acclaimed Elliptic Curve Digital Signature Algorithm (ECDSA). ECDSA, based on the principles of elliptic curve cryptography, is a cornerstone of modern cryptographic systems and provides a secure and ef...
TheECDSA(Elliptic Curve Digital Signature Algorithm) is a cryptographically securedigital signature scheme, based on the elliptic-curve cryptography (ECC).ECDSArelies on the math of thecyclic groups of elliptic curves over finite fieldsand on the difficulty of theECDLP problem(elliptic-curve discrete ...
Support fordigital signatures, which provide authentication of data using public-key cryptography. All algorithms reside in the separate crates and implemented using traits from thesignaturecrate. Crates are designed so they do not require the standard library (i.e.no_std) and can be easily used ...
JWT.create().sign(Algorithm) 其中Algorithm可以取值如下: 想要使用ECDSA算法需要提供一个ECDSAKeyProvider或一个ECPublicKey和一个ECPrivateKey,这里选择后一种方式实现。 3.2 密钥对处理 官方并没有提供如何生成ECPublicKey/ECPrivateKey的方法,甚至连从文件读取密钥对的方法都没有提供,笔者从官方提供的测试代码中发现...
