Is C# 'RSACryptoServiceProvider' cryptographic algorithm is a part of Microsoft- CryptoAPI? Any advantage we have for normal asymmetric encryption by using CryptoAPI over 'RSACryptoServiceProvider' in .Net? I cannot understand the difference between them?And which one is best and safty? Could yo...
对称密钥算法(英语:Symmetric-key algorithm)又称为对称加密、私钥加密、共享密钥加密,是密码学中的一类加密算法。这类算法在加密和解密时使用相同的密钥,或是使用两个可以简单地相互推算的密钥。 1.2 对称加密的优点 算法公开、计算量小、加密速度快、加密效率高,适合对大量数据进行加密的场景。 比如 HLS(HTTP Live...
