关于“EC KeyPairGenerator not available”的问题,这通常意味着你的Java环境中没有配置支持椭圆曲线加密(EC)的密码算法提供者。以下是一些解决此问题的步骤: 确认问题: “EC KeyPairGenerator”是Java Cryptography Architecture(JCA)中用于生成椭圆曲线密钥对(公钥和私钥)的组件。 检查环境配置: 确保你的Java环境中...

public final classECKeyPairGeneratorextends java.security.KeyPairGeneratorSpi This class generates EC public and private key pairs. An application can specify the key size, key label, storage type and usage type of the key pair to be generated via an instance of theAlgorithmParameterSpecclass. Th...
Integrating these classes with your project is very simple. For example, after including the necessaryPhactorclass files (or using an autoloader), to generate keypairs: $key=new\Phactor\Key;$info=$key->GenerateKeypair(); An associative array will be returned upon success: ...
