Digital signature and certificates on Mail

Hello All,
I'm new using mac and i have a token with my digital certificate. So i wanna know:
How can i use subscribe or use a digital signature on Mail. How can i use my certificate to sign the message.
Thanks,
Altemir Pacheco

Altemir ... It's important that the certificate has been created for the e-mail address you want to use as sender e-mail. Your certificate needs to be imported into keychain. Keychain only accepts certificates in a number of formats, among them .p12. You can import in a number of ways, you can for example drop your .p12 file (the certificate) on the keychain icon. Then open keychain and check whether the certificate is visible under "my certificates". It has to appear there and it has to show as "valid" and not as "expired". Control-click on the certificate and set-up a new preferred identity for your e-mail address (I am not sure whether this step actually does any difference but give it a try). Close mail.app and restart mail.app. When you now create a new e-mail and you choose as sender e-mail the e-mail address for which you have the certificate then you should see on the right side, just below the subject line a little symbol which you can click on for activating the signature for the e-mail your writing. Hope all this works.

Message level security: difference digital signature and certificate

Hi everybody,
could anybody please explain the difference between <b>digital signature</b> and <b>certificate</b>?
Thans
Regards Mario

Mario,
A digital signature is an electronic signature that can be used to authenticate the identity of the sender of a message or the signer of a document, and possibly to ensure that the original content of the message or document that has been sent is unchanged. Digital signatures are easily transportable, cannot be imitated by someone else, and can be automatically time-stamped. The ability to ensure that the original signed message arrived means that the sender cannot easily repudiate it later.
A digital signature can be used with any kind of message, whether it is encrypted or not, simply so that the receiver can be sure of the sender's identity and that the message arrived intact. A digital certificate contains the digital signature of the certificate-issuing authority so that anyone can verify that the certificate is real.
where as
A digital certificate is an electronic "credit card" that establishes your credentials when doing business or other transactions on the Web. It is issued by a certification authority (CA). It contains your name, a serial number, expiration dates, a copy of the certificate holder's public key (used for encrypting messages and digital signatures), and the digital signature of the certificate-issuing authority so that a recipient can verify that the certificate is real. Some digital certificates conform to a standard, X.509. Digital certificates can be kept in registries so that authenticating users can look up other users' public keys.
hope it helps u.

Digital Signatures and Certificates

I use Adobe Profession 8,
I installed a certifcate on my computer (certnew.cer) which has my informations and stuff on it.. ok so far. We have our own certificate server.
When i try to apply a signature on a pdf i created, my name is not on the list (Adobe). The only options i have is to create one or import one (.pfx, .p12). I dont mind importing one but it cant import .cer files.
Testing on another computer, after installing his certificate, his name was shown on the list in adobe.
Is there something that I can be doing wrong?
Is there are way to import a .cer file instead of a .pfx, .p12?
Is there an easy method of converting a .cer to .pfx (.p12) apart from using Windows Drivers Kit?

A cer file doesn't have a private key. It contains a public key and other certificate data. Signing requires a digital ID which includes both the cert/public key and the private key, and these are usually stored in pfx/p12 files.
Self-signed digital IDs are inherently less secure, but they can be made more secure if the recipient verifies the cert "thumbprints" that the signer shares ahead of time. . .
Comprehensive digital signature instructions exist in this doc:

Digital Signatures and Certificate Authorities

My users are wanting a way to sign PDF documents, and have them verified for internal and external receipients. We are currently using Acrobat 9 Standard. I know you can create signatures and 'self-sign' them, but those are only trusted if the receipient manually adds them to their 'Trusted' people.
From my reading, it looks like we need to purchase a third party code signing certificate, such as the following: http://www.verisign.com/code-signing/
My question is, what do we need to do to make that certificate availbable to my users to use for their signatures? I'm having a hard time finding documentation on this part.

Here's a good starting point for understanding how CDS and AATL work with Acrobat and Reader: http://learn.adobe.com/wiki/display/security/Digital+Signatures+101
Another option you should look into is Adobe EchoSign: http://blogs.adobe.com/acrobat/tag/echosign

Digital Signatures and Encryption in Yosemite Mail

After upgrading to Yosemite, I am having difficulty using the Mac Mail app to send digitally signed and encrypted email.
Before the upgrade to Yosemite, I was able to send signed and encrypted emails using certificate/keys in my keychain using both the Mac Mail app and Microsoft Outlook 2011 for Mac.
After upgrading, I am still able to send signed and encrypted message in Outlook, but the Mac Mail app gives the following error when I attempt to send a signed email:
'You don’t have a trusted certificate in your keychain that matches the email address “XXXX@XXXX”. Without a certificate, you can’t sign messages sent from this address.' (Actual name replaced)
When I look at my certificates in my keychain, a certificate is available with "Usage: Digital Signature" that has the email address from the error message "XXXX@XXXX" with exact case in the RFC 822 Name.
Another interesting piece of data that might help track this down is that when I first launch the Mac Mail application, the Mac Mail application is able to successfully decrypt emails that have been previously sent encrypted to me. HOWEVER, after I attempt to send an email and get the "You don’t have a trusted certificate..." error message, these emails are no longer able to be decrypted. I get the "Unable to decrypt message" header above the message and the content of the message is just a "smime.p7m". If I close the mail application and restart it, these encrypted message are once again decrypt-able until I attempt to send a message.
It almost seems like things are working until mail tries to access the keychain.
I have attempted to delete my certificate and keys from my keychain and then adding those items again.
I have attempted to close the mail application and reopen it.
I have attempted to reboot my computer.

1. I want to confirm that this is still an issue for me in 10.10.1 and mail Version 8.1 (1993)
2. I have another data point.
At my office I have wired networking and wireless networking available. Primarily I utilize the wired networking for access to network drives, etc.
When using the wired networking, I experience all the problems that have been catalogued in this thread. Can't sign, can't encrypt, can't close the compose window after the mail program fails to find my certificate.
However, when I switch to wireless networking before starting the mail application, digital signatures and encryption seem to work! This is pretty weird behavior. Make sure to restart mail if you were previously wired.
Here are some theories:
Something to do with OCSP? When I am wired vs wireless I am on different ip subnets and subject to different firewall rule sets. Perhaps OCSP is trying to determine the status of the certificate and failing?
Here are some things I have tested:
I switched to a different official apple brand thunderbolt to ethernet adapter with no change in behavior
I disabled wireless and disconnected my wired network. So no network access at all. Signatures and encryption work! The message obviously does not send, but it appears in my outbox and I don't get the signature error. When I reconnect my wired cable, the message sends successfully and appears as encrypted in my sent folder!
I have attempted to disable OCSP by using "Keychain Access --> Preferences --> Certificates Tab --> OCSP (OFF) and CRL (OFF)" but this hasn't made a difference in the behavior of wired networking.
Ran a TCPDUMP on traffic to the OCSP service but didn't see any traffic when I attempted to send a message and received the signature error
I am pretty stumped on this. This is very odd behavior
Does anyone else experience this behavior?

Digital Signatures and APEX

Has anyone had any success implimenting digital signatures (PKI) within APEX?
Here is a brief synapsis of what we are looking to accomplish and realize that third-party hardware/software might be necessary. We require users to login using LDAP credentials. We want them to be able to generate documents (i.e. PDF, Word, or Excel) from our application data. We want the users to have the ability to Digitally Sign their documents. We will be issuing individual private keys & certificates and we are considering generating the documents as XML. We are still in requirements gathering, but wanted to explore any and all capabilities within APEX.
Any thoughts? Thanks.

Digital Signature and SharePoint 2013

Dear Expert,
My company has a plan to do digital signature and sharepoint 2013. Now, we focus for internal use that I know use AD CS. and in near future we use for external use. We plan to buy 3rd party certificate.
My question
1. How to implement this solution? Please suggest
2. If I implemented AD CS, can we use public certificate in near future.
3. Can we use public certificate with SharePoint 2013?
Thank you

Hi,
Based on your description, my understanding is that you want to use Digital Signature in SharePoint Server 2013.
You can use digital signatures in forms ,then use these forms in you SharePoint site.
In InfoPath form ,you can change the form to allow signature here: File>Info>Advanced form options >Digital Signatures .You can choose to sign the whole form or a field .

besides, here is a similar post, you can take a look at:

PKI- Digital signature and doc cypher

Hello everybody, I have a problem and I need help please. This is my situation:
I would like to cypher a world document and add a digital signature. I want to use certificates to do so. That is why I have developed a PKi in order to get certificates to use digital signature and ASYMMETRIC encryption. I have to add that I am trying to assure
non repudiation, integrity and confidentiality of word documents.
Is there any way to do it? if so, how can i do it and what software application do you recommend? thanks!

As Elke explains and shows via that link, that informs you how to digitally sign a document. However a digital signature only provides non-repudiation and integrity of a document, not confidentiality. Symmetric Encryption is needed for that.
You would not use Asymmetric encryption to bulk encrypt files, it would be too slow.
Unfortunately there is no easy way to symmetrically encrypt files with the tools available in modern Windows distributions. Personally I would digitally sign the document, then use a tool like 7-Zip
to encrypt them with AES-256 and a passphrase, or to go one better than that use Symantec Encryption Desktop. Using the latter allows you to do encrypt either with a passphrase, or with
your targets PGP public key (that does of course assume they are also using PGP) so that only they can decrypt it with their private half.
Also signing an Office document (or PDF for that matter) with an internal PKI certificate is only valuable if the documents are internally distributed within the same organisation, or when the other organisation(s) trust your root CA certificate, otherwise
they will not be able to verify the signature (think of it like the error in your browser with the red X stating there is a problem with your certificate).
I'm not quite sure what your use case is, but if it's just for distributing internal documents then no problem. Otherwise you'll have to get a document signing certificate from a vendor like
GlobalSign who have a trusted root certificate which ships with most operating systems so that anyone who receives the document can verify it.

Digital signatures and wet ink signatures

HI all,
I am in the process of converting our paper checklists into fillable pdf forms. Everything is working well, but Im trying to get my head around digital signatures.
Ideally I just want to click the signature part, choose a user from a list, enter the password and the 'wet ink' signature that is scanned in gets added to the form.
So on my laptop I setup a new appearance for my signature, scanned my signature and added it to my digital signature. Perfect.
Problem is, I want to be able to use this on other computers. I copied the digital signature .pfx file and imported it on that new computer, which worked, but it drops the 'wet ink' signature and appearance.
It also appears that anyone can create a digital ID on my laptop and choose my wet ink signature appearance, and sign the document which makes it appear as if I have signed it. I was hoping the wet ink signature was locked with the digital signature but it appears this isnt the case.
Im trying to find the best way to store our signatures (we are all on a network), so that any user can use any computer and ideally lock the wet ink signature to the digital signature.
Many thanks
Chris

It doesn't work for everyone, but if you are considering moving to the world of digital signatures, it's best to forget the signature appearance ("wet"). This is just a distraction to the actual signature, and it encourages a deeply flawed workflow: one where people look at the picture on the page rather than learning about digital signatures and how to verify them. Since digital signatures are (if done properly) unfakeable and (in some places) legally recognised, it is best to completely change workflow, rather than trying to give the illusion it is just an electronic version of a paper workflow.

Java SSF for Digital Signatures and Document Encryption

Hello,
I have read in "SAP Help - Java Development Manual" that there is a Java SSF library for Digital Signatures and Document Encryption API.
http://help.sap.com/saphelp_nw04s/helpdata/en/4f/65c3b32107964996a56e4165077e24/frameset.htm
I am trying to develop an example application in NWDS using Interfaces/classes (ISsfData, SsfDataXml...), but NWDS does not find this classes in any library.
I have searched for Javadocs in NWDS plugins directory and this classes and interfaces should be in JAR com.sap.security.api.jar, but they aren't there.
Our WAS version is: NW04s WAS 7.0 SP11 and he have downloaded Java Crypto Library (IAIK) and also SAP XML Toolkit.
Does anyone know how to find or obtain this library?
Thanks in advance,

Digital Signatures and Coldfusion

I want to add a digital signature field (3 to be exact) to a PDF file that I
generate via coldfusion (via the cfdocument tag), OR use a form built in livecycle that once it is signed by the first person, the only allowable changes to the form are the second and third digital signature.
Any help would be appreciated as digital signatures are not handled in cfdocument as well (at all) as I had hoped.
Thanks,
