Get ExtensionValue from x509Certificate - certificate

I use bouncycastle in Java
CertificateFactory.getInstance("X509", "BC")
certFactory.generateCertificate(in)
to generate the cert. It works fine. But when I use
x509Certificate.getExtensionValue("1.2.3.4.5.6.7")
The return value does not match the membersrvc's one.
Did I miss some thing?

With bouncycastle you can do this to extract the ASN1 structure of the extension
public ASN1Primitive getExtensionValue(X509Certificate certificate, String oid) throws IOException {
byte[] bytes = certificate.getExtensionValue(oid);
if (bytes == null) {
return null;
}
ASN1InputStream aIn = new ASN1InputStream(new ByteArrayInputStream(bytes));
ASN1OctetString octs = (ASN1OctetString) aIn.readObject();
aIn = new ASN1InputStream(new ByteArrayInputStream(octs.getOctets()));
return aIn.readObject();
}
ASN1 is a complex object, you need to parse it to get the desired field. For example to Give back the CA URI meta-data found within the given X509 cert.
public String getIssuerURL(final X509Certificate certificate) throws Exception {
final ASN1ObjectIdentifier ocspAccessMethod = X509ObjectIdentifiers.id_ad_caIssuers;
final byte[] authInfoAccessExtensionValue = certificate.getExtensionValue(Extension.authorityInfoAccess.getId());
if (null == authInfoAccessExtensionValue) {
return null;
}
ASN1InputStream ais1 = null;
ASN1InputStream ais2 = null;
try {
final ByteArrayInputStream bais = new ByteArrayInputStream(authInfoAccessExtensionValue);
ais1 = new ASN1InputStream(bais);
final DEROctetString oct = (DEROctetString) (ais1.readObject());
ais2 = new ASN1InputStream(oct.getOctets());
final AuthorityInformationAccess authorityInformationAccess = AuthorityInformationAccess.getInstance(ais2.readObject());
final AccessDescription[] accessDescriptions = authorityInformationAccess.getAccessDescriptions();
for (AccessDescription accessDescription : accessDescriptions) {
final boolean correctAccessMethod = accessDescription.getAccessMethod().equals(ocspAccessMethod);
if (!correctAccessMethod) {
continue;
}
final GeneralName gn = accessDescription.getAccessLocation();
if (gn.getTagNo() != GeneralName.uniformResourceIdentifier) {
continue;
}
final DERIA5String str = (DERIA5String) ((DERTaggedObject) gn.toASN1Primitive()).getObject();
final String accessLocation = str.getString();
return accessLocation;
}
return null;
} catch (IOException e) {
throw new Exception(e);
} finally {
IOUtils.closeQuietly(ais1);
IOUtils.closeQuietly(ais2);
}
}
To return a human-readable string from an ASN1Primitive
public String getStringFromGeneralName(ASN1Primitive names) throws IOException {
ASN1TaggedObject taggedObject = (ASN1TaggedObject) names ;
return new String(ASN1OctetString.getInstance(taggedObject, false).getOctets(), "ISO-8859-1");
}

How to encrypt data in one app and decrypt it in different Windows app with RSA keys tied to local system?

I have a setup where I need to encrypt blob of data in one app and decrypt it in different app.
I built a sample app that creates a named CngKey object. Then create a RSACng using CngKey object. Then use RSACng object to do encryption/decryption. What I found is that the key changes across restarts of the application even though it is loaded using the name it was created with. I am lost trying to understand the relation between CngKey and RSACng objects.
Below is snippet of code that describes what I am trying to do:
using System;
using System.IO;
using System.Security.Cryptography;
namespace TPMCrypto
{
class Program
{
static byte[] data = { 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20 };

}
else

KeySize = 2048
};
privateKey = rsaKey.Key.Export(CngKeyBlobFormat.GenericPrivateBlob);

I am aware of dpapi and how to do this using it. I don't want to use it for this, please don't point me in that direction. I am using CNG flavor of crypto to force C# use NCryptXYZ crypto calls and the desire is to secure the keys in TPM.
Ah, looking at your code again, you've made a goof.
RSACng rsaKey = new RSACng(cngKey)
{
KeySize = 2048
};
Setting the KeySize property on an RSACng does one of two things:
If get_KeySize == value, ignore the input, do nothing.
Else, detach from the current key and the next time the key is used, generate a new key of get_KeySize at the time.
So you're opening an existing key, then discarding it, and generating a new ephemeral key. (Which you could see by checking rsaKey.Key.Name, it won't match your input).
Presumably you did this as a way to create the key with the right size in the first place, but you're too late. The correct way is
CngKeyCreationParameters cng = new CngKeyCreationParameters
{
KeyUsage = CngKeyUsages.AllUsages,
KeyCreationOptions = CngKeyCreationOptions.MachineKey,
Provider = CngProvider.MicrosoftSoftwareKeyStorageProvider,
Parameters =
{
new CngProperty("Length", BitConverter.GetBytes(2048), CngPropertyOptions.Persist),
},
};

Open OSM pbf results in Protobuf exception

Using OSMSharp I am having trouble to open a stream for a file (which I can provide on demand)
The error occurs in PBFReader (line 104)
using (var tmp = new LimitedStream(_stream, length))
{
header = _runtimeTypeModel.Deserialize(tmp, null, _blockHeaderType) as BlobHeader;
}
and states: "ProtoBuf.ProtoException: 'Invalid field in source data: 0'" which might mean different things as I have read in this SO question.
The file opens and is visualized with QGis so is not corrupt in my opinion.
Can it be that the contracts do not match? Is OsmSharp/core updated to the latest .proto files for OSM from here (although not sure if this is the real original source for the definition files).
And what might make more sense, can it be that the file I attached is generated for v2 of OSM PBF specification?
In the code at the line of the exception I see the following comment which makes me wonder:
// TODO: remove some of the v1 specific code.
// TODO: this means also to use the built-in capped streams.
// code borrowed from: http://stackoverflow.com/questions/4663298/protobuf-net-deserialize-open-street-maps
// I'm just being lazy and re-using something "close enough" here
// note that v2 has a big-endian option, but Fixed32 assumes little-endian - we
// actually need the other way around (network byte order):
// length = IntLittleEndianToBigEndian((uint)length);
BlobHeader header;
// again, v2 has capped-streams built in, but I'm deliberately
// limiting myself to v1 features
So this makes me wonder if OSM Sharp is (still) up-to-date.

Java: Crypto Bad Padding Exceptions

I really need some help. I am working on this assignment in school. I'm supposed to read a txt file into a list or string, and Encrypt that list of string, save it and Decrypt it back into a list of string. I was able to Encrypt it and save it, but when I try to Decrypt it back,
it give me an error message about Bad Padding.
I really don't how to fix this problem. Any help will be really good.

Creating custom plugin for chinese tokenization

I'm working towards properly integrating the stanford segmenter within SOLR for chinese tokenization.
This plugin involves loading other jar files and model files. I've got it working in a crude manner by hardcoding the complete path for the files.

URL issue in Facebook in BlackBerry

I have integrated Facebook in my app and trying to share some content.When I call FaceBookMain() ,it shows error like :
