Signed and encrypted message

I am working on a applicaion that can load a message from a third party software.
The message is signed and encrypted and will be sent via https.
My application is running on the Tomcat 5.0.24
And I have certificate from the third party software
However, I don't know **how** to use the certificate to decrypted the message.
For example, do I need to write Java code to decrypted the message or does Tomcat take care of the decryption?
If I need to write the code to decrypted the message, what API I should use?
If Tomcat cares of the decryption, how does it work? Do I need to modify the configuration file and how?
Thanks.

As for the rest, the devil is in the detail and you don't give any.

Signing and encrypting the message

Hi all,
How we can do signing and encryption of message with multiple certificates at XI adapter.As it's a XI adapter,we can't use adapter modules for this purpose..
What's the other way around?Any Clues..??
Thanks,
Anoop

I want signed and encrypted file on my target side from my second XI server.But i have to use FTPS receiver adapter at my second XI server.Now while encrypting my msz,i m have to use multiple certificates.The problem and limitation is, that the FTPS adapter is only taking/accepting the first SOAP attachment and is ignoring any further. This means, that the attached signature would be ignored by FTPS adapter.So, m validating the same at my First XI server so that it goes a single message to my second XI server.Hope it's clear now..
Thanks,
Anoop

Signing and Encryption Error PI 7.0

Hi All,
The scenario is
1) Two XI boxes are connecting with each other using XI adapter. Earlier there was signing and encryption certificate used
for data transfer and was working successfully.
2) From last 2-3 weeks source XI system is getting error in Call adatper as mentioned below. Then we tried to remove signing and encryption certificate so we disable both end the security check. And tried to send normal message but then also we are getting following error in Call adapter in SXI_MONITOR
Signature error Error while valdiating the digital signature. Theerror was com.sap.security.core.ws.wss.NoSecurityHeaderException No wsse:Security header has been defined for role soap:finalActor. Please verify the
Error during message security handling in inbound channel: Security profile 'Check Signature and Decrypt Message'
3) The SM59 connection is working fine. We have tried cache refresh. But still issue is not resolved.
Please guide

Hi Abhay
Probably the issue is with the public keys which are stored in both the XI boxes , as both the keys will be same .
Also check digital signatures which are maintained .

Unable to digitally sign or encrypt messages in Mail

I recently switched from a PC to a Mac and I have been unable to digitally sign or encrypt any of my e-mails. I'm currently running version 3.3 (926.1/926) for Mail and I made sure that my .cer security certificate is located in Keychain Access as well as certificates for my contacts. My certificate is valid because it has the green checkmark next to it.
I know what the *digitally sign* and encryption buttons should look like and where they should be located when composing e-mails, but they are just not there for me. Does anyone have any advice on how to fix this. Does it matter which folder the .cer security certificates should be located in for Keychain Access? Or is there a specific option I need to enable within Mail to be able to see those buttons?
I know that Mail is recognizing security certificates for e-mails that are being sent to me because it is showing the starburst/checkmark icon next to those e-mail addresses, and my Address Book is showing that same icon next to those e-mail addresses for my contacts.

I finally have a solution to this problem. I had been trying to use a .cer security certificate issued by Comodo, it had worked just fine on Windows but my Mac didn't seem to like it. I also tried creating my own certificate through OSX, but even after I created it I still couldn't see the buttons.
I had someone direct me to this webpage which ultimately helped me fix the problem:
http://allforces.com/2007/03/02/email-security/
I ended up using Thawte to issue me another security certificate (this time it was an x.509 file), the security certificate automatically opened in Keychain Access and downloaded to the Certificates and My Certificates folder. Once I shutdown Mail and restarted it I had the buttons for both encryption and digitally signed. Of course the encryption button is still greyed out because it is a new certificate and I need to make sure my Address Book contacts have a copy of it before I can encrypt.

Can't digitally sign and encrypt email any longer.

I used to sign and encrypt my emails digitally and then send them to people. I had two email certificates from Comodo, and it's been a while they're expired. so I renewed my certificates and deleted the old ones from my keychain, then downloaded and added the new ones. The trouble is I no longer get the digitally sign the message and encrypt the message button when I compose a new email. What could be the problem? how can I fix this?

I am now having the same problem. Have you seen a resolution yet?

Simple question involving data signing and encryption

What is exactly mean by signing and encrypting data?
And how would it apply to the case of a web browser..where I have to sign and encrypt data to and from a web browser? In this case it is an output and input stream.
Does every byte have to be signed or just the starting bytes? Singing every byte would make the process slow and inefficient

I know if you you sign and encrypt the data to the
web browser, it will obviously not be recognized but
this is my scenario:Your ASCII art didn't come across at all, I'm afraid - I'm not sure what you were going for, but I can't seem to recreate it. I think I can follow the explanation, though.
P is the program i am developing. It is supposed to
encrypt and sign data to and from the web browser.
P1 get the web browser request, encrypts the data
a and is supposed to sign the data...send it
to P2 which decrypts and verifies the signing which
then forwards it to the proxy or the server as seen.
Vice versa from the server response.So you're working on a web-proxy that encrypts it's transmissions, and you want to add signature verification as well.
My question still remains...how do you sign a stream?I answered your question, actually. You don't sign "streams" - you sign "messages". In your case, you sign the entire transmission, and then you transmit it.
Right now I am using RSA keys to send a symmetric key
across safely for the decryption etc I have the
encryption/decryption process covered and the browser
works..but i didn't do signing of any sort...how to
implement this..for every byte? Is signing necessary?Given your requirements, I have to ask - why are you re-creating SSL? If you have P1 and P2 talk SSL to each other, you get everything you've described here, including signing. I don't understand why you feel the need to recreate an existing protocol.

Encoding configuration for signed and encrypted emails

I have a 8820 device (no BES server) - I have certificates downloaded and trust on the device. I can attach the requisite certificates to the message, but I do not have the option to select signing or encrypting encoding. the menu does not give me this option. I have the S/MIME package installed. Any thoughts / pointers?

The S/MIME support package is only supported with a BES. You might try Djigzo for BlackBerry. Djigzo for BlackBerry is an add-on to the Djigzo Email Encryption Gateway which can be used to send and receive S/MIME digitally signed and encrypted email from a BlackBerry smartphone. An installation of the Djigzo gateway is required.
Djigzo for BlackBerry and the Djigzo gateway is open source and can be freely used.

Mesage-Level Signing AND Encrypting Web Services?

Hello,
I have a Web Service on a Weblogic 9.2 that is able to encrypt or sign it's output messages but when I want to use both together I get the following error:
WSSecurityException: Signature failed to validate. Reference: #Body_B1Zi6a4UPGCpLPRh does not validate.
Could this be an ordering problem of signing and encryption and do I have any influence on what should be done first?
By the way signing and encrypting input messages from a consumer works fine. I'm not using any user defined ws-policy files.
thanks for help

I found out now that encryption alone does not work properly as I thought it would. The messages look fine on TCP-Monitor and I get no Exception or error message but the response content is empty, all fields are null.
Does anybody know if there is a bug with empty encrypted responses? (Sending and encrypted Request to the service works and it's content fields are not empty.)
regards

Outlook 2013: Cannot sign or encrypt messages

I've done clean install of Windows 8.1 and forgot to copy my certificate. Luckily I have offsite backup so I imported the certificate into path
"Certificates\Personal\Certificates" in MMC console (under my user account as well as computer account).
But I cannot sign or encrypt messages in Outlook 2013. Outlook says "Outlook had problems encrypting this message because the following recipients had missing or invalid certificates (my e-mail address here)".
Moreover I cannot see incoming encrypted messages, Outlook says "Sorry, we're having trouble opening this item. This could be temporary, but if you see it again you might want to restart Outlook. Your Digital ID name cannot be found by the underlying
security system."
I checked E-mail Security in Trust Center and everything seems to be OK, my certificate/DigitalID is installed, enabled and valid. I also have imported colleague's valid certificate in
"Certificates\Trusted People\Certificates".
I have Audit Failure in Event Log which says:

Issue while Signing and Encrypting the PDF Document.

Hello,
I am developing one component in VC++(MFC) which signs and encrypts the pdf documents.
When i sign and encrypt pdf document using my component, I am getting following error while opening the document in Adobe Acrobat
Error during signature verification
Unexpected byte range values defining scope of signed data.
Details: The signature byte range is invalid
But if i open that document in binary mode and calculate the byte range its looking correct.
The Process for signing and encrypting the PDF document is as follows :
1)Prepare the PDF document for signing (Add Annotation objects,n0,n2
layers,create blank signature field,new xref section etc.)
2)Encrypt the whole document(Password based encryption).
3)Put the ByteRange values.
4)Write the signature in blank signature field.
If i just perform encryption(128 bit RC4 Algorithm) on the pdf document its working fine.Only after adding the signature objects i am getting above error.I think it means something is wrong in signature related objects,but i am not able to recognize the exact problem.
So what can be the issue?
Please Help
Thanks in Advance

Is there a way to select which algorithms are used for signing and encryption when using S/MIME with the Mac Mail app?

Hi Abhay
Probably the issue is with the public keys which are stored in both the XI boxes , as both the keys will be same .

How can I sign and encrypt massage to send via rmi ??

Hi,,,
I want to sign a massage with RMI client private key and then encrypt the message with the signature using the RMI server public key.
How can I do this ?

I suspect you won't like my answer but a good starting point is "Beginning Cryptography with Java" by David Hook published by Wrox.
P.S. It is much more secure to use RMI with secure sockets since this provides both authentication and encryption and most of the work is done by existing system libraries.
