A Secure Message is a Short Text Message that can be sent and received securely using
. Secure Messages share the same communication infrastructure provided used for secure voice.
EVSS do do not relay at all on Apple Push Notification or Google Cloud Messaging, in order to protect users' security:
...
Secure Messages are text only, thus no attachments are provided. Maximum length of a Secure Message is 160 characters.
How does a Secure Message work?
When a user chooses to send a Secure Message, it triggers an HTTPS POST request in his client towards
which plays a "store-and-forward" role. If recipient is online, Secure Message is immediately delivered. Otherwise it is stored temporarily in
up to 3 days before expiring: as soon as the recipient pops up online,
delivers the Secure Message.

Secure Messages compared to
...
regular Text Messages (SMS)
Secure Messages provide a user experience very similar to SMS, adding security and with some minor differences. Some current constraints will be relaxed in next versions.
...
- You cannot attach anything to a Secure Message: Secure Messages are actually text only.
- Secure Message length is fixed to a maximum of 160 characters.
- Each Secure Message has a time validity, after which it expires. Expiration means that the Secure Message content is no longer readable and it's gone for good. Instead of message content you'd rather read "Message received" or "Message sent".
Each time you send a Secure Message you can see a status icon appearing on its side. Here follows an explanation of each icon along with its status name and meaning:
| Icon | Description | Meaning | Timeouts and general behaviour |
|---|
| Image Modified | Sending Message | is actually trying to send the Secure Message to its recipient via | If there is some network issue, then starts the retry procedure: it tries to send 5 times the message to . If it fails at the fifth try (5 * TLSTimeout = 60 secs), then the message remains in the client queue waiting for one of the following triggers:- The user can connect to Sip Server
- The client sends a SIP KeepAlive to the server
- The user sends another message
If more than 12 hours passed and the message is still in client queue waiting to be sent, then the message expires: a "Send error" notification is fired by and the message is removed from local queue |
| Image Modified | Message Enqueued | Secure Message has been enqueued in encrypted storage and will be delivered to recipient as soon as possible. | If delivery is not possible because the peer if offline, retries as soon as recipient registers for up to an expiration period (72h), before removing them definitely from the database. |
| Image Modified | Message Delivered | Secure Message has been delivered to recipient's device, who could have read it or not. | None |
| Image Modified | Error sending Message | This status is a fall back for any other one and it's triggered both by timeouts and error responses. | None |
