 Make sure to store the passphrase safely and securely in a password manager or so, otherwise you can not get to your data any longer or everyone can do so.

+**Remark**
+Sometimes, gpg tries to ask for the passphrase via the configured pinentry app, which sometimes fails. In those cases add
+
+```
+--pinentry-mode loopback
+```
+
+to the commandline:
+
+
+```
+gpg --pinentry-mode=loopback --symmetric --cipher-algo AES256 --armor --output secrets.asc secrets.txt
+
+gpg --pinentry-mode=loopback --decrypt --output secrets.txt secrets.asc
