 Sample 1. Assign value to BigInteger upon validating the value using BigIntegerValidator ( Apache Commons )

BigIntegerValidator bigIntegerValidator = BigIntegerValidator.getInstance();
BigInteger bigInteger = bigIntegerValidator.validate("1AD2345");
System.out.println(bigInteger); // prints null as the validation fails because of non numeric characters

 Sample 2. Check if the numerical value is within a specified range using BigIntegerValidator ( Apache Commons )

System.out.println(bigIntegerValidator.isInRange(12, 0, 100)); // prints true because the value 12 falls in range 0-100

 Sample 3. Code Sample / Example / Snippet of java.math.BigInteger

    private X509Certificate generateRootCertificate(String commonName, Date notBefore, Date notAfter) throws Exception {

X500Name issuer = new X500Name(commonName);

BigInteger serial = BigInteger.probablePrime(16, new Random());



SubjectPublicKeyInfo pubKeyInfo = convertToSubjectPublicKeyInfo(m_caKey.getPublic());



X509v3CertificateBuilder builder = new X509v3CertificateBuilder(issuer, serial, notBefore, notAfter, issuer, pubKeyInfo);

builder.addExtension(new Extension(Extension.basicConstraints, true, new DEROctetString(new BasicConstraints(true))));



X509CertificateHolder certHolder = builder.build(new JcaContentSignerBuilder(SIGNATURE_ALGORITHM).build(m_caKey.getPrivate()));

return new JcaX509CertificateConverter().getCertificate(certHolder);
