The receiver cannot decrypt my emails

You need to clear your key cache.

• On a BlackBerry device: Do a battery pull

• On an Android or Secure Phone device, follow the instructions:

1. Open the app drawer and select Key management.

2. Tap Manage public keys and select the Cached tab.

3. Find and tap the user with whom you have problems communicating.


This will delete the key associated with the selected account. The new key will be downloaded automatically from the server.


To make sure that your contacts’ public keys are always up to date, go to Settings > Keystore settings and turn off Use cached keys. Note, that this may slow down the app performance because the receiver’s key needs to be checked on server level each time you send a message.
