Encrypting email using .Mac certificate

With 10.4.3, iChatAV gets a secure and encrypted chat feature. This requires a paid .Mac account, which generates the certificate for you.
On first launch of 10.4.3, I was able to use the .Mac certificate to encrypt and sign Mail.app mail.
Now, I have re-installed 10.4 (now running 10.4.3) and re-issued a new .Mac certificate (revoke the old one), I can no longer encrypt and/or sign. Secure iChatAV still works.
HELP.

Hi, I don't use Entourage so I can't help you much, but you might want to post your question or do a search here in the MS Office for Mac community since this is the MacBook hardware forum. Hopefully someone else here can help you out though.
Cheers

I am unable to open encrypted emails using webmail and a CAC reader. It says "content can't be displayed because the S/MIME control isn't available." I'm using a Macbook Pro with 10.10 OS and have tried both Safari and Chrome.

I am using a Macbook Pro with OS X Yosemite 10.10.2. I am unable to open encrypted emails using webmail. I have verified my certificates are loaded in the keychain for my military common access card while using a CAC reader.

We used to get a 'whooshing' noise when we sent an eMail using mac Mail. This no longer happens. We recently updated to Mountain Lion 10.8.1 Can anyone throw light on this please? David

Encrypt Emails using PKI Infrastructure (X.509 Certificates)

Dear HTMLDB Fans,
i wonder if anybody ever needed to send passwords via email to the enduser and how you are doing this via plsql. As far as i can see there is no easy way to send encrypted Emails with a Plsql Package. I read that Oracle took over the PHAOS Company in order to fullfill Requirements in the Security Area but there must have been some solutions out there before?!
The way to do it seems preety easy.
1. Download the public Key of an User you want to send an email.
2. Encrypt your Message with that Key
3. Send your Message
Any Hints are appreciated.

I tried using demo_mail and DBMS_OBFUSCATION_TOOLKIT but it doesn't seem to be able to deal with x.509 certificates.....
Has anyone succeeded before me?

Anyone had trouble sending emails using mac pro

Until recently I was sending and recieving email with no problem using my Mac Mail and home router to a Hotmail server. About 2 weeks ago I was unable to send emails to anyone it came back with the message smtp server not responding. I know the server is ok because I can send from other PCs and via web mail on the Mac. I have concluded there is a mismatch between my router and Mac Mail application and wondered if any one else has experienced this. More importantly do you know how to fix it?
Any advice is welcome

Simply it is Mac Mail. For any reason, or no reason at all, it just stops sending or recieving mail.
If you want to forgo these type problems in the future switch to some other, ANY OTHER, Mail program.
Mac Mail is the worst. If you don't believe me just do a search of these forums for Mail Stopped sending Mail, or Can Recieve but can't Send.
I use Thunderbird on all my computers, PC and Mac, and have not had one problem with it in the year+ I've been using it.
I used Mac Mail for about a day and said "There Has to be Something better". I then switched to Thunderbird on the Mac then a few days later switched my PCs, multiples, to Thunderbird.

Cannot send email using mac mail and yahoo att

I recently was hacked and changed my att yahoo password and security questions. I got a confirmation email about this but not about changing the password. I can receive mail, but not send any. All my settings in preferences seem to be correct. The TLS certificate is not check however, and I'm wondering if that has something to do with it. The port number has not been changed, nor the outgoing service address: which is: smtp.att.yahoo.com: (followed by my email account name). I've had this email address for years and want to keep using it. apparently Yahoo has been having allot of problems over the last few days and I've found it hard to access their trouble shooting sites and log in page. Is there something I can do on my end to fix this? Thanks.

Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.

Can't send emails using .mac accounts? Finally the solution!!! Nice & Easy!

Found this after searching these discussions for over an hour, and it really works, but you MUST create a new account, don't edit your existing one. Very quick & easy!!! Here you go, courtesy of Guillermo Toro-Lira:
OK guys, problem solved, at least for those with a dotMac account like me.
You have to create a new MobileMe account in your iPhone using your new MobileMe email address ( [email protected] instead of [email protected] ).
Select Add Account... on Settings->Mail, Contacts, Calendars. Then MobileMe, enter your name, MobileMe address, password and description and select Save. The system will validate your account first. Then go back to Accounts, select your dotMac account and select delete. Your new mails, contacts, calendars will be sync'd by your new MobileMe account.
It looks like iPhone classic 2.0 requires your new MobileMe address ([email protected]) to send emails.

I accessed my .Mac account with the iPhone's mail client with my first generation iPhone for over a year including for a while after the change to MM before I purchased my iPhone 3G.
The first generation iPhone and the iPhone 3G are capable of running the same firmware so there is no difference between the two in this regard. To say the first generation iPhone requires creating and accessing the @Me account instead of the @Mac account is incorrect.
If this is true with many, how come not a single person has chimed in with this thread saying the same thing?

Mail uses wrong certificate for encrypting S/MIME messages

Encrypted email I send using Mail Version 4.2 (1077) under OS X 10.6.2 to my work account cannot be decrypted. It appears that Mail is using the signing certificate, rather than the encryption certificate, to encrypt the email.
The internal Certificate Authority at my employer has issued two certificates to me: A signing and an encryption certificate. Both certificates are properly stored in my keychain.
The encryption certificate carries a 0x20 in the key usage field to designate the certificate to be used for encipherment purposes. The signing certificate carries a 0x80 in the key usage field to designate the certificate to be used for digital signatures.
I understand that the S/MIME standard stipulates that for encrypting messages, the certificate with 0x20 in the key usage field should be used by the mail application.
However, messages I sent are encrypted using the signing certificate (0x80 in the key usage field) and therefore cannot be decrypted on the receiving end. I examined the encrypted email using an [application|http://www.eriugena.org/blog/?p=57] to extract the serial number of the certificate used for encryption.
We are using Outlook 2003 as our mail application at work.
Has anybody ever come across this problem? Am I missing something - is there a way to tell Mail what certificate to use for encryption?
Thanks,
-Michael.

I'm have a problem that sounds related.
Both my wife and I created self signed mail certificates, and sent email to each other and trusted each others certificates. We were then able to send encrypted emails back and forth and our emails showed up as having trusted digital signatures.
Then, we both purchased Verisign email certificates, and installed them in our keychains, deleting the old self-signed certificates, and repeated the process of establishing a chain of trust.
This worked fine for me running Snow Leopard but did not work for her on Leopard. Her emails to me appear to be signed by both the old self-signed certificate and to include the new verisign certificate. Looking at the message source there is only one application/pkcs7-signature block, but in the UI it is showing both certificates.
I don't understand how the self-signed certificate is showing up at all, since it has been deleted from her keychain.

How do I use outlook digital id's to read encrypted email?

I'm strugging with this one. I have an exchange account that makes use of digital ID's to encrypt email using MS Digifal ID's. Is there a location or feature on the iPhone4 where I can use the imported ID to let me read email that's been encrypted with s/mime on the iphone4?

OR... *sorry" is there a third party application that I can put on the iPhone4 to allow me to do this?

Sending Encrypted Email

I am having problems sending encrypted email using Mail 2.1. I have imported my certificate file into my keychain. The certificate, encryption and decryption keys appear in my login keychain. If I am reading the mail how-to correctly I should simply need to click on the compose mail icon where I should see the icons to sign or encrypt the email message. I do not see these icons. The interesting thing is that I seem to be able to receive encrypted messages. (Incoming encrypted messages are visible and show the security: encrypted identifier in the header) I am guessing that I am missing something in the way my certificate is installed/ configured. Unfortunately, I am not having any luck figuring out what I am missing. Any suggestions?

I have not tested sending encrypted email with Apple's Mail application yet, but I think I can shed some light on your problem. Encryption requires knowledge of the recipients' public keys, which is part of the recipients' certificates, not just your own certificate.
Check out http://www.joar.com/certificates/. Specifically, it states:
The easiest way to let Mail know that a recipient has a certificate, and to give Mail access to that certificate, is to have that recipient first send you a signed message (not encrypted, just signed). Mail will automatically store the certificates it receives in the Keychain for future reference.
The encrypt button will not be visible when the recipient doesn't have a certificate, or if it has one but you don't have a copy of the certificate stored in your Keychain.

Sign and encrypt in Mail with certificates?

Hi there
maybe I'm just to stupid, but how can I install certificates (e.g. Thawte) in order to sign and/or encrypt emails using the mail.app in iphone?

User cannot cc self when encrypted emails

I have a user that can send encrypted emails and recieve encrypted emails using her encryption certificates. However if she CCs herself in an email to someone else (who does successfully recieve and open encrypted messages regularly from her) the error
message says some users in the CC list cannot recieve encrypted mail. Send unencrypted?
The users public keys were published the GAL and other users regularly successfully send and recieve encrypted emails from her.
any ideas where the problem could be?

If she can send, receive, and open encrypted email then there is nothing
wrong with her certificate or with its being published to the GAL. I would
look at the email client as the problem and as such, you should probably
post your question in a forum for whatever email client she's using, rather
than here.
Someone should also probably teach her about the Sent items folder. There's
no reason to cc one's self in the first place.

Problem sending emails with Mac Mail 1.3.11

Desperately in need of help. I'm able to receive but not send email using Mac Mail. I keep getting an error message:
"This message could not be delivered and will remain in your Outbox until it can be delivered.
The sender address [email protected] was rejected by the server"
I have already tried the following at the advice of AppleCare reps:-
Have verified & repaired disk utilities & keychains
Have reinstalled the operating system
Have trashed the mail.plist file
Have trashed the outbox.mbox file
Getting quite frustrated now because we have a mac bookpro with identical mail settings and it is able to send and receive mail without any problems.Could it be the version of Mail I'm running ?
I initially thought that the problem related to having switched to a new ISP but the fact that one of the mac's has no problem has led me to be less convinced of that idea.
Any suggestions gratefully accepted.
Many thanks

I am having the same problem exactly. I can read e-mail, but get the same error message trying to send it. I can't use .Mac anymore--have to use alternate e-mail for the last month--since some time in October 2006.
I haven't changed anything on my G4, haven't upgraded anything, and the problem started about the time .Mac reported some customers were unable to use Mail for a couple of days in October.
I see nobody answered your post. Did you ever get your mail to work? I have repaired permissions, but I don't think it has anything to do with that.
Thanks,

How do I use the Certificate Assistant to set up secure email for clients

I was at first thrilled to find the Certificate Assistant, and now I'm frustrated. I need to have secure, encrypted email for my psychotherapy clients. I thought that if I created my own certificate authority and then issued certificates to my clients, I would be fine. But I can't get this to work. I set up my own authority, but when I try to get a certificate (using a different email account) I can't get it to work. For example, I go to the website created on mac.com and click the "download an invitation" button and then click the download, which opens the Assistant. I fill out the form, but I get an error saying I haven't configured an email account. How do I "configure" an email account? I mean, I use this account all the time; what more configuration does it need?
Second question. Will anybody with a Windows machine be able to use that webpage? Seems like it's a mac only program, so what good is it in the real world?
I know I could try to do this with Thawte or whatever, but asking my clients to get trusted so I can use encryption is unreasonable. If not having my own authority (if I could get THAT to work) is there any other way? Are there any good things to read about this? With the federal HIPAA privacy requirements, there are lots of doctors wrestling with this question.

If you are referring to your "iCloud account", then simply tap "settings / iCloud" - delete the account you are currently logged in with, and add the correct one.
