[[!meta title="OpenPGP passphrase encryption"]]
With <span class="application">Tails gpgApplet</span> you can **encrypt text
with a passphrase** using the passphrase encryption of OpenPGP.
[[!inline pages="doc/encryption_and_privacy/gpgapplet.warning" raw="yes"]]
<div class="note">
<strong>This technique requires you to share a secret passphrase with the people
who will decrypt the text.</strong> OpenPGP also allows you to use public-key
cryptography to send confidential messages without having a shared passphrase.
[[See the corresponding documentation.|gpgapplet/public-key_cryptography]]
</div>
1. Write your text in a text editor. **Do not write it in the web browser!**
For example, open <span class="application">gedit</span> from the menu
<span class="menuchoice">
<span class="guimenu">Applications</span> ▸
<span class="guisubmenu">Accessories</span> ▸
<span class="guimenuitem">gedit Text Editor</span></span>.
2. Select with the mouse the text that you want to encrypt. To copy it
into the [[!wikipedia Clipboard_(computing) desc="clipboard"]],
right-click on the selected text and choose <span
class="guimenuitem">Copy</span> from the menu.
<span class="application">Tails gpgApplet</span> now shows
lines of text, meaning that the clipboard contains non-encrypted text.

text"]]
3. Click on <span class="application">Tails gpgApplet</span> and select <span
class="guimenuitem">Encrypt Clipboard with Passphrase</span> from the menu.
If you receive the error message “<span class="guilabel">The clipboard does
not contain valid input data</span>”, try to copy your text again, starting
from step 2.
4. In the <span class="guilabel">Passphrase</span> dialog box, enter a
passphrase of your choice. Repeat the same passphrase in the second dialog box.
5. <span class="application">Tails gpgApplet</span> now shows a
padlock, meaning that the clipboard contains encrypted text.
[[!img gpgapplet_with_padlock.png link=no alt="Tails gpgApplet with a
padlock"]]
6. To paste the encrypted text into another application, right-click in the
application where you want to paste it and choose <span
class="guimenuitem">Paste</span> from the menu.
For example, you can paste it into the web browser to send it by email.
[[!img browser_paste.png link=no alt="Encrypted text starting with
-----BEGIN PGP MESSAGE-----"]]
<div class="next">
You can also [[decrypt a text that is encrypted with a
passphrase|decrypt_verify]] using <span class="application">Tails
gpgApplet</span>.
