Digital Signatures and Email Encryption on iPhone

One of our clients has implemented a policy whereby all email communications with vendors must be digitally signed and encrypted. I know SSL allows the iPhone to create an encrypted connection to the email server. However, is there a way to actually digitally sign and encrypt an email sent via the iPhone...or to receive a digitally signed or encrypted email on the iPhone?

Maybe there is a separate email client app in the App Store that supports PGP or S/MIME (the built-in email doesn't).

  • 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 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 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.

  • 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 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?

  • Digitally Signed and/or Encrypted Emails -- Can't Scan or Search

    I work in an environment where we enforce digital signatures and encryption on emails when certain conditions exist in the body of the email (e.g. hyperlinks, attachments, etc.).  What we've found, over the years, is that Exchange 2010 doesn't appear
    to be able to read the body or attachments on emails that are signed or encrypted.  We've found this because Transport rules consitently fail against these emails and Search-Mailbox fails to return results against test emails that have been digtially
    signed/encrypted using Body or Attachment keywords as criteria.
    Has anyone else run into this, can explain this, or know if there is a workaround/hotfix?  I heard from someone that Exchange 2013 fixes this issue but need a resolution for 2010.  Any assistance would be greatly appreciated.

    No you're right.  The customer keeps coupling the two because of their adjacency in Outlook and I repeated it because I've been hearing it all day.  The limitation of encryption is well understood but digitally signed emails are only plain-text
    with added s/mime data.  However, this latter case still seems to baffle Exchange 2010 -- Transport rules don't act upon rules based on body-content and attachments and Search-Mailbox will not report users' mailboxes as having mail that's searched for
    if it's digitally signed.

  • Digital Signatures and Encryption

    .NET and Workshop using digital signatures and encryption.

    Hi Amber,
    The work is based on the finalization and imminent publication of the

  • Looking for "PDF Public-Key Digital Signature and Encryption Specification"

    Hi,
    i am looking for the following ("old") document:
    PDF Public-Key Digital Signature and Encryption Specification
    Originally i could be found here:
    http://partners.adobe.com/asn/developer/acrosdk/DOCS/ppk_pdfspec.pdf
    But not anymore. Does somebody of you still have it? Adobe today just offers the latest documents but i specifically need that older version.
    Or is there an archive i don't know of?
    Thanks for your help,
    ToM

    You can read the PDF 1.5 specification OR even ISO 32000-1 itself for that information. Each feature is "tagged" with the specific version in which it was introduced.
    Digital Signatures were first introduced in Acrobat 4 (PDF 1.3) and have seen various improvements which each version since.

  • 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 .
