I use APG (Android Privacy Guard) on my Android phone for this:

https://play.google.com/store/apps/details?id=org.thialfihar.android.apg

I use the IMAP client "K-9 Mail" which uses APG for PGP functionality.

https://play.google.com/store/apps/details?id=com.fsck.k9

K-9 Mail only supports inline PGP though. I'm not aware of any email
application on Android which provides PGP/MIME support at this time.
The authors of K-9 Mail have been saying for over two years now that
they will provide PGP/MIME support. I'm no longer optimistic about this.

It's also worth noting that The Guardian Project is working on porting
GnuPG to Android:

There is APG (Android Privacy Guard) in Google Play Store, which can
be used by e.g. K9 Mail, which can sign, decrypt and encrypt messages.
I am not sure can it generate keys, by itself, but it accepts keys
created in gnupg.

More information at [APG home page] and [K9 Mail Google Code page].

Thank you both for replying to my question about IPODs and Androids. It sounds like neither will work to be fully functional with gnupg or pgp then. Perhaps I should get a small laptop computer. I wonder if one of those small driveless computers and a USB storage device would work. I need an inexpensive solution for a friend.in Europe. Since Poland and the Ukraine are in the European Union there shouldn't be any problem using pgp for private communication among friends right? I have been using pgp since the 90's as a hobby and believe if privacy is not use it will be lost. I used to chat with Julf at Anon penit fi back then to but not with pgp.

APG functions on android remarkably well, with key servers and key
generation features. The only thing missing that comes to mind is the
WOT side. As long as this is between friends, that becomes relatively
unnecessary. Also possible is to just import pre existing keys. Also of
interest would be whether sufficient entropy exists on the device to
actually generate a secure key, so caveat emptor, so to speak. Both
elgamal and rsa keys of up to unspecified sizes can be generated, but
the instructions within the app suggest 8192 at least; more than
sufficient. As noted in another reply, PGP/mime is not supported. That
functionality may be an issue, but given all three of the replies that
I've seen to your query (including mine) are inline, that shouldn't be a
problem with day to day operations.

Attachments do not have sigs produced for them when emailed, but you can
manually encrypt them using the APG app before attaching them to an
email. K-9 works well with that app. File compression and message
compression are both supported, most if not all of the encryption and
hashing algorithms commonly found in gnupg are incorporated, and the app
even supports ASCII armoured docs. All in all, an excellent tool.
Someone recently forked the APG app, around the same time I was looking
at doing the same, since the project has been inactive for nearly two
years. His name escapes me, but he also manages the ad-away app. Also,
The Guardian Project is porting gnupg.

All in all an excellent project, highly recommended.

oPenGP Lite (couldn't find any version without the 'Lite'). This version works one way, it decrypts only, doesn't encrypt. This is a PGP Corporation (owned by Symantec now) App, hence the upper case PGP in oPenGP.

I don't know whether there is, or will be, a Mobile GnuPG what will work under iPhone or iPad iOS.

I generated on my Mac a new key pair (default RSA/RSA 2048). I didn't want to use my "regular" key.

Exported the secret key to the Mac's Desktop.

Connected the iPhone via iTunes (hardwired USB)

Imported the secret key to the iPhone via iTunes and an App called 'Files' <http://www.olivetoast.com/files/>.

In 'Files' I could see the key block, select all/copy.

Back to oPenGP, Import clipboard, ascertained that the key is now in the keyring.

Back to 'Files', set an access locked code. Checked that it works. Deleted the secret key keyblock.

Sent myself a test message encrypted with the public key of the above keypair.

Downloaded the e-mail in iPhone, select all/copy.

Back to oPenGP, Import/Decrypt Clipboard, enter the passphrase.

It works.

I don't feel at ease having my secret key in my iPhone, but i can learn to live with it, if I really want to use this iPhone feature. I'm not sure I want to.

Charly


So ios can use PGP on iphones and ipads?

What are the security issues? How safe is the private key and pass phrase on these devices?

GnuPG is a crypto tool, which implements standards like OpenPGP
and Cryptographic Message Syntax.

An email application is needed in addition
to read and send OpenPGP/MIME or S/MIME emails.

(There are other tools, that also implement those standards.)

So your question can be understood in several dimentions:
a) is there a port (or distribution) of GnuPG
for Android?

Not really. Details: There used to be
https://github.com/guardianproject/gnupg-for-android
but it is unmaintained and outdated.
So it is technically feasable, but not one does the work.

b) is there a port (or distribution) of GnuPG
for iOS?

Not that I know of.
Details: There are probably technical and license challenges to port
GnuPG to iOS. While I believe that it is possible to port C applications
to iOS, it is unclear if someone could place it is in the appstore.
Note that GnuPG ports to MacOSX exist.


c) Are there compatible OpenPGP and OpenPGP/MIME implementations for
Android?

Yes, e.g. Openkeychain + K9Mail (both being Free Software)


d) Are there compatible OpenPGP and OpenPGP/MIME implementations for iOS?

Yes, though proprietary Software (AFAIK), for example I've heard about
Canary Mail, iPGMail, PGPro, Safe Easy Privacy

Bernhard

PGPro is open source, but neither it nor iPGMail handle openPGP/MIME -
they use various tricks with the clipboard and attachments to exchange
ciphertext with the native iOS mail app, due to restrictions in iOS
<=v13 that forbid third-party apps direct access to the mail delivery API.

(The less said about SAFE Easy Privacy's hateful UX, the better)

Canary Mail is the only one of the above which has (so far) taken
advantage of the new iOS 14 app policy to implement openPGP/MIME. I have
not used it much, but it appears well-built (and closed-source, and pricey).

I can also name following Android Apps here

- FairEMail (+ Openkeychain)
- R2Mail2
- MailDroid (+ Crypto-PlugIn)

which supports BOTH OpenPGP and S/MIME.
All of them are available for a small fee.

thanks for sharing your experiences?

Anyone cares to link this from wiki.gnupg.org?
To me it would be cool, if more details are available there,
I do sometimes updates some, but more help would be cool. ;)
