目前我正在使用BouncyCastle库来生成证书.像这样的东西:
X509V3CertificateGenerator certGenerator = new X509V3CertificateGenerator();
certGenerator.setIssuerDN( rootCertificate.getSubjectX500Principal() );
certGenerator.setSignatureAlgorithm( "SHA1withRSA" );
certGenerator.setSerialNumber( serial );
certGenerator.setNotBefore( notBefore );
certGenerator.setNotAfter( notAfter );
certGenerator.setPublicKey( rootCertificate.getPublicKey() );
Hashtable<DERObjectIdentifier, String> attrs = new Hashtable<DERObjectIdentifier, String>();
Vector<DERObjectIdentifier> order = new Vector<DERObjectIdentifier>();
attrs.put( X509Principal.C, "RU" );
// other attrs.put() calls here
order.addElement( X509Principal.C );
// other order.addElement() calls here
certGenerator.setSubjectDN( new X509Principal( order, attrs ) );
certGenerator.addExtension( X509Extensions.AuthorityKeyIdentifier, false, new AuthorityKeyIdentifierStructure( rootCertificate ) );
certGenerator.addExtension( X509Extensions.SubjectKeyIdentifier, false, new SubjectKeyIdentifierStructure( newKeyPair.getPublic() ) );
return certGenerator.generate( …
