Bouncycastle java.security.NoSuchAlgorithmException:没有这样的算法：提供程序BC的SHA1 WithRSA

我尝试用以下代码验证PKCS#7签名：

public static void verifypkcs7(String content, byte[] signedBytes) throws OperatorCreationException, CMSException, IOException, CertificateException, NoSuchAlgorithmException, NoSuchProviderException, CertStoreException, NoSuchStoreException
{
    Security.addProvider(new BouncyCastleProvider());

    CMSProcessableByteArray cmsByteArray = new CMSProcessableByteArray(content.getBytes("UTF-8"));
    CMSSignedData sp = new CMSSignedData(cmsByteArray, signedBytes);

    Store                   certStore = sp.getCertificates();
    SignerInformationStore  signers = sp.getSignerInfos();

    Collection<?>              c = signers.getSigners();
    Iterator<?>                it = c.iterator();
    boolean verified = false;
    while (it.hasNext())
    {
        SignerInformation   signer = (SignerInformation)it.next();
        Collection<?>          certCollection = certStore.getMatches(signer.getSID());

        Iterator<?>        certIt = certCollection.iterator();
        X509CertificateHolder cert = (X509CertificateHolder)certIt.next();
        verified = signer.verify(new JcaSimpleSignerInfoVerifierBuilder().setProvider("BC").build(cert));
    }
    System.out.println(verified);
    CMSProcessable signedContent = sp.getSignedContent() ;
    byte[] originalContent  = (byte[]) signedContent.getContent();
    System.out.println(new String(originalContent));
}

例外情况发生在：

verified = signer.verify(new JcaSimpleSignerInfoVerifierBuilder().setProvider("BC").build(cert));

我试着在谷歌上搜索解决方案，但毫无帮助。你能帮帮我吗

在将Unbase64用作第二个参数之前，请尝试此操作，但应切换到较旧的bouncy castle版本。我用了1.45
