Sending public key to not java application

Hi,
I'm trying to send through a socket connection a public key encoded on X.509 standard, but the key.getEncoded() method returns a array of bytes,How can I convert this array of bytes to a sequence of characters that can be readable by any not java application???Is possible to make this public key readable for any not java application??How can I do that??
How can I send the public key to a not java application??
Thanks.

Thanks for helping, but if I use Base64 encoding does the client have to use a base64 decoder before having to use the public key??
The major problem is that my client is a perl application that uses openSSL, I think it will not understand the key if I send it in Base64(the perl application uses a openSSL API to make the received public key in X.509 back to public key)...

ArchiveLink security: sending public key certificate by SCMS_HTTP_PUT_CERT

Hello!
I have a question which I asked on ESA and Security forums and didn't get answer.
I am trying to do a test program to check ArchiveLink security features. Namely, I am calling the function SCMS_HTTP_PUT_CERT which is supposed to send a public key certificate via HTTP. However, when I catch this call and want to import the certificate by using the function SSFC_PUT_CERTIFICATE, I get error message SSF kernel error: invalid parameter.
Does anyone have experience with this?
For more detailed description of my attempt, please see ArchiveLink security: sending public key certificate.
Thanks and regards,
Igor

Hi
SCMS_HTTP_PUT_CERT is used to send sap public key to Content server application. The content server application makes use of this key to verify the incoming request ie the Content Server uses the public key to check URIs and signatures.
SAP uses the Public/Private key security concept while communicating with Content server. Basically when SAP communicates with Content server it will be sending GET, PUT, POST requests. The URL from SAP will have field called secKey which contains the security key. secKey ensures that a URL cannot be changed after it has been generated by the SAP system. The private key is used by SAP to generate the secKey.
The content server application will use the public key provided via SCMS_HTTP_PUT_CERT to check the URL and will be able to detect if the URL has been tampered.
Refer SAP Content Server HTTP 4.5 Interface documentation section Security for more details.

AD CS Web Enrollment Error - "public key does not meet the minimum size required"

I've installed a standalone root CA and a enterprise subordinate CA in our environment - both are Windows 2008 R2. Everything is working except for Web Enrollment using a custom User template. I duplicated the default User template and choose
2003 Compatible for the new one. I changed the minimum key length to 2048 and set the validity period to 2 years.
We'd like to avoid using the Advanced Certificate Request page, so I modified certrqtp.inc to point to the new template:
Else
' Request types for enterprise
rgAvailReqTypes(0,FIELD_TEMPLATE)="User-custom"
rgAvailReqTypes(0,FIELD_FRIENDLYNAME)=L_UserTemplateCert_Text
rgAvailReqTypes(0,FIELD_CSPLIST)="Microsoft Enhanced Cryptographic Provider v1.0?Microsoft Base Cryptographic Provider v1.0"
rgAvailReqTypes(0,FIELD_CSPLIST2)="Microsoft Base Cryptographic Provider v1.0?Microsoft Enhanced Cryptographic Provider v1.0"
rgAvailReqTypes(0,FIELD_EXPORTABLE)="True"
nAvailReqTypes=1
End If
I also ran into this issue where Web Enrollment jumps straight to the Advanced page if the original User template isn't present on the CA:
http://social.technet.microsoft.com/Forums/en/winserversecurity/thread/9ab514bc-1f9f-424e-b70d-705874d9c623
So I have both User templates loaded on the CA, and I get this error back when attempting a certificate request using IE 8 or 9:
Your certificate request was denied.
Your Request Id is 25. The disposition message is "Denied by Policy Module".
Contact your administrator for further information.
Looking at the CA's Failed Requests section, I see this error:
The public key does not meet the minimum size required by the specified certificate template. 0x80094811 (-2146875375)
I double-checked our custom template and it does specify 2048 as the minimum key size.
Also, when trying with Chrome 11.0, I get an extra option during enrollment asking for a key size (1024 or 2048). When I choose 2048, the certificate request succeeds. I don't get the key size option when using IE, though.
We'd like to get this working with IE if possible. Any ideas?

We had the same error message. The problem turned out to be on the requesting computer, not the server. When we went to renew a cert in IIS on a server it was generating a 1028-bit key request. Since the minimum on the server was set to 2048-bit
the request failed. So, there's two ways to handle this. You can change the certificate template on the server to have a minimum set to 1024-bit or you can have IIS submit a new request for a certificate and choose 2048-bit as the size of the key during the
wizard. We opted to have IIS request a 2048-bit key. The same would apply for whatever computer, device, or software you are using to form the certificate request.
Your message is pretty old, but I am running on the same problem right now. I've added a custom template to select (with 2048) minimum length, but the webpage from the IIS by default provides just 1024-bit. Where can i optimize the IIS to use a 2048-bit
key when requesting the certificate?
When I open the same site with Firefox for example, i got a listed option (Medium / High Strength) to choose for the encryption. It seems that the high strength is >= 2048-bit.

How to grab global shortcuts keys in a java application?

Hi!
Does anybody know if it's possible to get the focus to a Java application, when it is not selected, using a keyboard shortcut key?
I've written a java application that provides shortcuts keys (like CTRL-M...) for accessing to some operations. For using those keys combinations my application has to be focused between the other opened applications on the operating system (Linux 7.3), as it should be in a normal behaviour... but, I would need that the operation associated to the shortcut key could be executed even if another application had the focus...
Is it possible? How this could be done?
Thanks in advance four your interest and your answers.

Unfortunately shortcuts will work only if your app is focused.

Importing public key certificate from external application

Hello!
I am trying to implement the following scenario:
1. External client application sends it's public key certificate to SAP WAS
2. SAP imports this certificate into its PSE
3. External client application sends digitally signed messages to SAP (with secKey HTTP call parameter)
4. SAP checks this signature and does whatever further action.
For simplicity reason, I emulated this "external app" by using the ArchiveLink interface of the very same SAP system. So, I have one system which is at the same time client and server, but the communication works via HTTP.
I started with step 1: The ArchiveLink (in my case "external app") uses the function SCMS_HTTP_PUT_CERT to send the public key certificate to the client via HTTP. It worked well - I received the message with HTTP service and it contained some binary content as expected (valid public key certificate - I suppose).
Unfortunately, I was unsuccessfull with step 2: How to import the received certificate into my PSE?
I debugged the STRUST transaction and saw that it uses the function SSFP_PUTCERTIFICATE to import public key certificate into SAP's own PSE. However, when I try to use it, I get error No temporary PSE available. I also tried to encode-base64 this message with the same result. What does this mean?
Does anyone has experience with this? Please share it.
Thanks in advance and kind regards,
Igor

The key point was understanding the cleverly named parameter PROFILE in the function SSFC_PUT_CERTIFICATE. You'd never guess: it's a path to a PSE where you want to put the certificate, in my case: C:\usr\sap\NSP\DVEBMGS00\sec\SAPSYS.pse. There's one more step: updating database with the file system PSE.
So, the test sequence that works is:
1. SSFP_GETSAPCERTIFICATE
2. SSFC_PUT_CERTIFICATE
3. SSFPSE_STORE

Igor

I want to send an email from my java application

i want to send an email from my java application

Then do so...
You'll probably want to use the JavaMail API (http://java.sun.com/products/javamail) to do that.

IOS 6.1 S/MIME public key does not install

Hi;
After an upgrade I am not able to install the key from an email. Previously this worked fine, and I would "view" the certificate and install the profile as it is called. But, now it does actually show the "intstall" button, but you cann not get it to press or install. The certificate is marked as trusted. Which I beleive indicates they have the chain correct.
The same person sends email to my Macbook and Apple Mail collects the key and put that into Keychain. So, it must be something on iOS6.1??

Thank you for the update!
Next I would recommend backing up your iPad to iTunes and restoring the device with this article

here is a code from
http://www.exampledepot.com/egs/java.security/GetKeyFromKs.html
This example retrieves from a keystore, the private and public key associated with an alias.
private and public key are having the same alias ?
i know a alias for my key but i believe thats for private key not for public key ......is it true that both private and public key have the same alias ?
and KeyPair is an interface and so its difficult to get a key out of it
public KeyPair getPrivateKey(KeyStore keystore, String alias, char[] password) {
 try {
 // Get private key
 Key key = keystore.getKey(alias, password);
 if (key instanceof PrivateKey) {
 // Get certificate of public key
 java.security.cert.Certificate cert = keystore.getCertificate(alias);
 // Get public key
 PublicKey publicKey = cert.getPublicKey();
 // Return a key pair
 return new KeyPair(publicKey, (PrivateKey)key);
 } catch (UnrecoverableKeyException e) {
 } catch (NoSuchAlgorithmException e) {
 } catch (KeyStoreException e) {
 return null;

Public Key Encryption

Hi guys,
I have to sign some data (a byte array) using a Public Key.
How can I do that?
(I know it's a bit strange..but I have to do this....)
Thanks a lot...bye!!

What you're really asking for is to do something with the data that only the owner of the Private Key can use. What you should be looking at is encryption with the Public Key and not Signing with the Public Key. You will find many examples on this forum, in the JCE web-pages at Sun and in David Hook's Book "Beginning Cryptography in Java".

Invalid Key Exception: Unsupported key type: Sun RSA public key, 1024 bits

I am trying to retrieve certificates from Microsoft Keystore and extract its keys using SunMSCAPI in jdk 1.6. It gives me an invalid key exception, when I am trying to wrap the Symmetric key (which was previously used to perform AES encryption on data), using RSA algorithm.
Code snippet:
 // RSA 1024 bits Asymmetric encryption of Symmetric AES key
 // List the certificates from Microsoft KeyStore using SunMSCAPI.
 System.out.println("List of certificates found in Microsoft Personal Keystore:");
 KeyStore ks = KeyStore.getInstance("Windows-MY", "SunMSCAPI");
 ks.load(null, null) ;
 Enumeration en = ks.aliases() ;
 PublicKey RSAPubKey = null;
 Key RSAPrivKey = null;
 int i = 0;
 while (en.hasMoreElements()) {
 String aliasKey = (String)en.nextElement() ;
 X509Certificate c = (X509Certificate) ks.getCertificate(aliasKey) ;
 String sss = ks.getCertificateAlias(c);
 if(sss.equals("C5151997"))
 System.out.println("---> alias : " + sss) ;
 i= i + 1;
 String str = c.toString();
 System.out.println(" Certificate details : " + str ) ;
 RSAPubKey = c.getPublicKey();
 RSAPrivKey = ks.getKey(aliasKey, null); //"mypassword".toCharArray()
 Certificate[] chain = ks.getCertificateChain(aliasKey);
 System.out.println("No of certificates found from Personal MS Keystore: " + i);
 // Encrypt the generated Symmetric AES Key using RSA cipher
 Cipher rsaCipher = Cipher.getInstance("RSA/ECB/PKCS1Padding", ks.getProvider().getName());
 rsaCipher.init(Cipher.WRAP_MODE, RSAPubKey);
 byte[] encryptedSymmKey = rsaCipher.wrap(aeskey);
 System.out.println("Encrypted Symmetric Key :" + new String(encryptedSymmKey));
 System.out.println("Encrypted Symmetric Key Length in Bytes: " + encryptedSymmKey.length);

Added [ code] tags to make code readable.

A bit of research indicates that the classes of the keys obtained by
 RSAPubKey = c.getPublicKey();
 RSAPrivKey = ks.getKey(aliasKey, null); //"mypassword".toCharArray()are sun.security.rsa.RSAPublicKeyImpl and sun.security.*mscapi*.RSAPrivateKey . It seems that for Cipher objects from the SunMSCAPI provider cannot accept RSA public keys of class sun.security.rsa.RSAPublicKeyImpl and that the SunMSCAPI will only accept RSA private keys of class sun.security.mscapi.RSAPrivateKey.
This came up under different guise a couple of years ago. It makes sense since encrypting/wrapping with a public key does not represent a security problem (there is nothing secret in any of the encryption operations) when done outside of MSCAPI so one can use any provider that has the capability BUT the decryption/unwrapping must be done with the SunMSCAPI provider which delegates it to the MSCAPI.
My working test code based on your code implementing this approach is :
 // RSA 1024 bits Asymmetric encryption of Symmetric AES key
 // List the certificates from Microsoft KeyStore using SunMSCAPI.

How to get Public Key Remainder?

Hi Friends..
Sorry, i have a little doubt regarding the Public Key Remainder..
What is Public Key Remainder used for?.. is it a part of Public Key?.. How to get it from Public Key, especially in Java?
As far as i know that the Public Key is constructed with Modulus and Exponent, and with this we can Encrypt and Verify data was signed by Private Key..
In Java, we can expose Public Key's modulus and public exponent using RSAPublicKey, there's no method to expose Public Key's Remainder..
Please help me regarding this..

In that case the exponent and remainder are you public key (exponent and modulus) and the certificate is defined in the definitions section of Book 3. It is a secure way of verifying the public key and it's owner through a trusted certification authority.
EMV Book 3 tends to use Remainder and Modulus interchangeably.You mean, the Issuer (in this case one of E,M, and V) should provide 2 certificates for 1 card?..
This is implemented on SDA or DDA?..
Sorry, i'm still have no idea..
The Remainder and Modulus should be used interchangeably?..
How the Host and Card can decides in each transaction whether it will use Remainder or Modulus?..I mean that the terminology is used interchangeably. They refer to the same thing as far as the actual key is concerned.

Cannot send a null Map key for type 'java.util.HashMap'

Hi All,
I am haing an issue with sending data from Server to the client using the AMF Channel.
Most of the method invocations on the RemoteObject are throwing the following Exception.
[CODE]
(mx.rpc.events::FaultEvent)#0
bubbles = false
cancelable = true
currentTarget = (null)
eventPhase = 2
fault = (mx.rpc::Fault)#1

[CODE]
The Spring bean which is exposed as a Remote Object has the following method signature..
[CODE]
public String getMapKey() {
        return mapKey;
[/CODE]
I am unable to understand why AMF Channel or Blaze DS is treating the String as HashMap !!!
This was working pefectly fine till yesterday !!
The version of the BlazeDS i am using is : blazeds_turnkey_3-0-0-544
and the Flex SDK Version is : flex_sdk_3.5.0.12683
We recently upgraded to Flex 3.5.0 version earlier we were using 3.3 version
Thanks

Hi All,
I chcked my server side java beans ( which are managed by Spring) and they are all returning the data property and none of the Keys in the returned hashmaps are null.
Not sure why this is happening.
Thanks
