Without getting into the innards of what PGP is and who it is for, I will assume that you are here because you straight away want to know how you can use PGP on your android device.
My setup is here, and I hope this works across most android devices, but just in case:
1. Android 4.3
2. Samsung Galaxy Note 3 SM-N900
3. Built-in e-mail client.
4. Assumption: You already have a key pair you wish to import and use.
(If you want to use a separate e-mail client, I highly recomend K-9 mail, which works very beautifully with APG, all available free in the Play Store).
- Transfer your key pair from wherever you store them, to your device. There are many ways to do this, but i use Dropbox.
- On the device, save the key par to /openpgp/export/ on the built in storage. You can export directly from Dropbox to any location on your device.
- Rename the keys to the following format:
_ _0x _Pri.asc
_ _0x _Pub.asc
For the private and public keys respectively. For example, if your email configuration is as follows:
E-Mail address: john@xxxxxxx.net
Name: John XXXXNET
Key ID: 0xABCD1234
Your file names would be:
john@xxxxxxx.net_John XXXXNET_0xABCD1234_Pri.asc
john@xxxxxxx.net_John XXXXNET_0xABCD1234_Pub.asc
4. On your device, import the key-pair as follows: Settings - your_email_account - More Settings - Security Options - Private (or Public Keys); then click "Import Keys" on the menu option.
Hope this helps.
