Change encryption and signing certifcate

Hi,
in my network I have Exchange 2007 and Outlook 2010/2013.
I need to replace the existing internal enterprise root Certification Authority with a new one.
Some people use the encryption email with certificates issued by current CA.
When will I replace the CA and install the new user certificate issued by the new root CA, what will happen to old encrypted emails ?
I need users to be able to read the old encrypted email.
Thanks
Andrea

Hi Andrea:
where do you want to apply this change?
For Email encryption, if public key of the old certificate is still available, user will be able to read the mail. Otherwise, no.

Timestamp Error when calling Encrypt and Signed Web Service

Hello,
I maked one Web Service in the Oracle Service Bus 10gR3 that supports Encryption and Sign, basically inserting (manually) this on WSDL Contract:
This two namespaces:
xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"
xmlns:wsp="http://schemas.xmlsoap.org/ws/2004/09/policy"
This Declarations:
<wsp:UsingPolicy Required="true"/>
<input>
<wsp:Policy>
<wsp:PolicyReference URI="policy:Encrypt.xml"/>
</wsp:Policy>
<soap:body use="literal" />
</input>
<wsp:Policy>
<wsp:PolicyReference URI="policy:Sign.xml"/>
</wsp:Policy>
The above declarations was inserted in the correct points inside the WSDL Contract and the Web Service is working correctly.
The Problem is related to Sign.xml declaration, when i insert this declaration:
<wsp:Policy>
<wsp:PolicyReference URI="policy:Sign.xml"/>
</wsp:Policy>
Then, the Web Service shows an error. Following the Request and Resonse (That shows the error):

Biztalk PGP encryption and signing

Hi,
Currently i am working on a custom pipeline component to PGP encrypt and sign the outgoing message from Biztalk 2013 with public and private keys.
I am referring the content mentioned in the below posts
https://code.msdn.microsoft.com/windowsdesktop/BizTalk-Sample-PGP-ebcbc8b2
http://bajwork.blogspot.co.nz/2007/08/pgp-pipeline-component.html
But we have a requirement to use PGP version 6.5.8 and i could not find what PGP versions the above components supports.
Any one has any idea about Biztalk and PGP version 6.5.8 for encryption and signing?
Thanks
JB

PGP has different versions and 6.5.8 is older one. If just download the Bouncy castle pgp dll, it’s not going to use the 6.5.8 version of PGP.
http://www.pgpi.org/products/pgp/versions/freeware/win32/6.5.8/
With latest Bouncy castle pgp dll, there are few issues encountered by the user you tried to use PGP version 6.5.8, especially around signature validation. Following are the discussion on
the issues faced..
http://stackoverflow.com/questions/7193323/encrypt-with-bc-and-decrypt-with-pgp-6-5-8
http://bouncy-castle.1462172.n4.nabble.com/ERROR-encrypted-session-key-is-bad-when-trying-to-decrypt-td1466221.html
http://bouncy-castle.1462172.n4.nabble.com/Compatibility-Issue-with-PGP-6-5-8-td1467170.html
People have manage to get it working with few changes to the PGP code (which you can get it here
http://www.bouncycastle.org/csharp/index.html )
This forum is not the right place to raise question about finding the Bouncy castle pgp dll version compactable with v6.5.8. try to post this question here
http://bouncy-castle.1462172.n4.nabble.com/
Once you have their dll compactable with v 6.5.8, then you can use it in BizTalk suggested by the links referenced by you.

Help required on Encryption and Signing.

Hello All,
Client:
Client is having his own Private key and the public key of the Server.
Server:
Server is having his own Private key and the public keys of all the clients.
When a client wants to send a document to the server with both encryption and signed,
then he will encrypt the document with the server's public key and then sign the encrypted document
with his own Private key.
And then sends it to the server.
When the server receives the signed object from the client, he has to verify the signature with
the public key of the client and he has to decrypt the document with the Pirvate key of the server.
How can we verify the signature?
By just saying,
Signature sig = Signature.getInstance("SHA1withRSA");
sig.initVerify(kp.getPublic());
boolean verifies = sig.verify(realSig);
where "realSig" is the signed object.
In this case i am unable to verify the signature. Even if i succeeded here in verifying the signature,
how do i decrypt the signed object.
My question is,
When the client sends signed object to server, does he sends anything else along with it?
Say for example if he sends the encrypted document along with the signed object then if i say,
Signature sig = Signature.getInstance("SHA1withRSA");
sig.initVerify(kp.getPublic());
sig.update(cipherText);
boolean verifies = sig.verify(realSig);
where "cipherText" is the encrypted document.
In this case i am able to verify the document and since i will have the encrypted document
along with the signed object i will decrypt this using the Private key of the server.
So is it must and should that i need to send the encrypted document everytime along with the signed object to the server.
Thanks and have a nice time.

I have two suggestions for you
First read a good book about cryptography. Even using secure cryptographic algorithms is no guarantee that your solution is secure. Without thorough understanding of cryptography and security someone might break in due to some implementation mistake in your security mechanism. My recommendations: "Applied Cryptography" written by Bruce Schneier and "An Introduction to Cryptography (IntrotoCrypto.pdf)" by Phil Zimmermann, Network Associates. This PDF document can be downloaded as part of the free PGP product from http://www.pgp.com, http://www.pgpi.com or http://www.nai.com
Second take a serious look at S/MIME. S/MIME allows information to be wrapped in signed and/or encrypted data blocks in a secure way. The S/MIME standard is around for a few years and has been thoroughly reviewed. Bouncycastle (www.bouncycastle.org) contains an library for creating and handling S/MIME data. Never invent your own formats when a standard is available. More information about S/MIME can be found at RSA labs (www.rsa.com or www.rsalabs.com).

S/MIME support in Mail (encryption and signing)

Hi,
is there S/MIME support in iPhones Mail-Client? Mail.app for OS X has great support for encrypting and signing eMails using S/MIME certificates and I wonder if iPhones Mail-Client is able to use S/MIME, too.
best,
Jens

I have the same question. Much of my mail comes with either S/MIME or GnuPG encryption. A device that lets me receive but not read my e-mail isn't much use for communication.
Can someone confirm?
Mac OS X (10.4.10)

No indication whether the email is encrypted and signed with S/MIME

I have been using OpenPGP/GPGMail V2.0b6 for email encryption for some time. Now I added S/MIME. What I noticed is that if I send an encrypted and signed email with GPGMail the header in the send mail will show that it was encrypted and signed. However, if I send an encrypted and signed email with S/MIME there is not notification in the mail header. Only be checking the send mail in the iPad was I able to confirm that the email was really encrypted and signed with S/MIME.
Does anybody else have experienced this?
Is there a solution to this problem?

I have now further analysed the behaviour of S/MIME encryption and signitures on the iPad (iOS 7.0.2) and the iMac (OSX 10.8.5).
I installed a Comodo free email certificate on my iMac and the same certificate on my iPad. Another Comodo free email certificate I installed on the iMac of a friend of mine.
Sending back and forth encrypted, signed or both encrypted and signed messages between iMacs and iMac and iPad works with no problem. In the iPad email header it is indicated with symbols wether the email is encrypted, signed or both encrypted and signed. On the iMac on the other hand only when the email is signed is that indicated with a symbol in the email header (see figure below).
When an email is encrypted or encrypted and signed is this not indicated with symbols in the email header. This is in contrast to OpenPGP. OpenPGP emails always indicate with symbols whether they are encrypted, signed or both encrypted and signed (see figure below).
I hope that in OSX 10.9 email header symbols will indicate whether emails are S/MIME encrypted, S/MIME signed or S/MIME encrypted and signed.

I had to change my email acct and do not have access to the original one my icloud, iTunes,etc have. I changed it and signed out and was able to successfully change to the new email on iTunes and Apple ID. However, I can not get icloud to change over and.

I can not get icloud to let me change the email to my new acct???

To change the iCloud ID you have to go to Settings>iCloud, tap Delete Account, provide the password for the old ID when prompted to turn off Find My iDevice, then sign back in with the ID you wish to use. If you don't know the password for your old ID, or if it isn't accepted, and if your old ID is an earlier version of your current ID, go to https://appleid.apple.com, click Manage my Apple ID and sign in with your current iCloud ID. Click edit next to the primary email account, change it back to your old email address and save the change. Then edit the name of the account to change it back to your old email address. You can now use your current password to turn off Find My iDevice on your device, even though it prompts you for the password for your old account ID. Then save any photo stream photos that you wish to keep to your camera roll. When finished go to Settings>iCloud, tap Delete Account and choose Delete from My iDevice when prompted (your iCloud data will still be in iCloud). Next, go back to https://appleid.apple.com and change your primary email address and iCloud ID name back to the way it was. Now you can go to Settings>iCloud and sign in with your current iCloud ID and password.

Re: help i can't push"change password and sign me"...

I can not keep changing my screennames to keep this up. Please email me at [email protected] Thank you Michelle Grissom

Hi Michelle,
You have more than one Skype account and some of them are blocked.
In order to sort out this problem you need to contact customer service: https://support.skype.com/en/faq/FA1170/How-can-I-contact-Skype-Customer-Service

How to process encrypted and signed PGP message in BC library ?

Message is encrypted by rsa and idea algorithm. I've got decrypted idea sesssion key. But i don't know how to decrypt this message (and what is the structure). Maybe somebody would post working code for that operation.

Here is another option.
I had the same problem with my Mac OSX System 10.8.4 after update cups from 1.6.2 to 1.6.3.
I have a MacBookPro with the same system version and copy the libcups.2.dylib file form /usr/lib/ then replace the error file in my other Mac.
1. Install cups 1.6.2 again
2. Replace the file libcups.2.dylib in /usr/lib/ directory with this one libcups.2.dylib
Note: I added the link if you dont have an other mac in the same version available.
This works for me.

WSE3.0 encrpyt and sign soap message together with disabled WSAdressing

Good Morning,
my task is to develop client´s applications written in .net4 who calls webservice (written by other- foreign firm in Java). My application, which calls webservice of other firm are: (plugin of MS CRM 2013, windowservice, windowformsapp for testing this communication)..
I had to implement encrypt and sign comunication with this webservice by client and servers certifikate.
I implemented this functions from:
http://msdn.microsoft.com/en-us/library/aa528788.aspx
and
http://msdn.microsoft.com/en-us/library/aa529565.aspx
by WSE 3.0.
Now I have to implement to disable WSAdresing in soap messege. Is it possible to use encrypt and sign from WSE together with disabled WSadressing?
(Other firm needs so as nodes of WSA will not be in soap message). With nodes WSAdresing in soap message, my communication with other webservice do not works. They (other firm) require no WSA nodes in soap message
If it is posible, how to implement this functionality?

I have most of my music stored on my old iphone. i bought a new I pad, and signed up with a new e mail adress as my old one is defunct. How do i change my e mail adress to the new one, because it keeps telling me apple id already in use.

You can change the primary email address on an account by logging into it via the 'manage your apple id' button on http://appleid.apple.com, or via the Store > View Account menu option on your computer's iTunes, or by tapping on it in Settings > iTunes & App Store on your phone and logging into it.
You won't be able to change it to an email address that is being used an alternate or rescue email address on the account (they can be viewed/changed/removed via http://appleid.apple.com), nor to one that is currently being used as the primary email address on an account

HT5622 I changed ISP and as a result, I lost the use of my email address which I used as my apple id. I changed my id on one iPad (I have two) but the change is not recognized on the 2nd. I keep being asked to sign in under the old id. What's up?

I changed ISP and as a result lost access to the email address I used as my Apple ID I went to the Apple ID page and changed my id to my new email address for my personal iPad. But when I use my other iPad, I am asked to login using my old email address and password. When I try to reset my id for the 2nd iPad, using the Apple ID page, it shows my new email. How do I import the hanged Apple ID to my 2nd iPad?

Sign out and sign in with new Apple ID
Settings>iTunes and App Store>Apple ID

Had to change my Apple ID because the original email address is no longer valid. How do I change the iCloud user name on iMac? I found instructions about signing out of iCloud and signing back end. It asks questions about contact, etc.

Had to change Apple ID due to email address no longer valid. Trying to change id for icloud...saw direction online about signing out of icloud and signing back in...when it ask questions about contacts, photos, etc. being deleted how do I answer those? That just sort of freaks me out.

For the ones that give you an option, select the option you want (keep on the Mac or Delete). For the ones that are simply warning you, click on Delete from Mac.
They will all come back when you sign back on, since all you did was change your existing Apple ID to a new email address. It's the same iCloud account, just with a different name.
It's the only way to get your updated ID signed onto iCloud.
Cheers,
GB

I find that the easiest way to change the account you are using on your mobile device is to scroll down to the bottom of the iTunes Store or App Store on the device and tap the Apple ID button. Then:
- To sign out, or to sign in to a different account, tap the Sign Out button.
- To sign back in, tap the Sign In button, then tap either Use Existing Apple ID or Create New Apple ID, and follow the on-screen instructions from there. I hope this helps.
