如何使用私钥对字符串进行签名

如果我已将私钥作为byte[]或String如何使用SHA1withRSA获取字符串的签名？

使用bouncycastle签署和validation签名的正确方法

我使用bcmail-jdk16-1.46.jar和bcprov-jdk16-1.46.jar （Bouncycastle库）来签名string ，然后validationsignature 。 这是我签署string code ： package my.package; import java.io.FileInputStream; import java.security.Key; import java.security.KeyStore; import java.security.PrivateKey; import java.security.Security; import java.security.Signature; import java.security.cert.X509Certificate; import java.util.ArrayList; import java.util.List; import org.bouncycastle.cert.jcajce.JcaCertStore; import org.bouncycastle.cms.CMSProcessableByteArray; import org.bouncycastle.cms.CMSSignedData; import org.bouncycastle.cms.CMSSignedDataGenerator; import org.bouncycastle.cms.CMSTypedData; import org.bouncycastle.cms.jcajce.JcaSignerInfoGeneratorBuilder; import org.bouncycastle.jce.provider.BouncyCastleProvider; import org.bouncycastle.operator.ContentSigner; import org.bouncycastle.operator.jcajce.JcaContentSignerBuilder; import org.bouncycastle.operator.jcajce.JcaDigestCalculatorProviderBuilder; import org.bouncycastle.util.Store; import sun.misc.BASE64Encoder; public class SignMessage { […]
