SecurityException: BC Provider Not Installed

Question

Writing code to create a digital certificate with BouncyCastle.

Here is an important part of the problem causing the code.

public X509Certificate generateCertWithKeypair(KeyPair caPair)
            throws InvalidKeyException, SecurityException, SignatureException {
        X509V3CertificateGenerator v3CertGen = new X509V3CertificateGenerator();
        v3CertGen
                .setSerialNumber(BigInteger.valueOf(System.currentTimeMillis()));
        v3CertGen
                .setIssuerDN(new X509Principal("CN=cn, O=o, L=L, ST=il, C= c"));
        v3CertGen.setNotBefore(new Date(System.currentTimeMillis() - 1000L * 60
                * 60 * 24));
        v3CertGen.setNotAfter(new Date(System.currentTimeMillis()
                + (1000L * 60 * 60 * 24 * 365 * 10)));
        v3CertGen
                .setSubjectDN(new X509Principal("CN=cn, O=o, L=L, ST=il, C= c"));
        v3CertGen.setPublicKey(caPair.getPublic());
        v3CertGen.setSignatureAlgorithm("SHA1WithRSAEncryption");
        X509Certificate generateX509Certificate = v3CertGen
                .generateX509Certificate(caPair.getPrivate());//**here**
        return generateX509Certificate;
    }

An exception

Exception in "main" java.lang.SecurityException: BC provider not installed!
    at X509V3CertificateGenerator.generateX509Certificate(Unknown Source)
    at chapter4.Dupe.generateCertWithKeypair(Dupe.java:74)
    at chapter4.Dupe.main(Dupe.java:32)

In the search, I found that the last jar solves the problem, but no luck.

Did I miss something?

You must "register" BC in the JRE. You can do this in two ways: put bcprov.jar in the $ JRE / lib / ext folder and add the line$JRE/lib/security/java.security

security.provider.n = org.bouncycastle.jce.provider.BouncyCastleProvider

bcprov.jar , java.security, -

static { Security.addProvider(new BouncyCastleProvider());  }
