[SIGFOX] “We are using the RC1692 Sigfox modules. Is it possible for us to encrypt the payload from the device to the tower, and from the tower/server to the user. As there are only 8 bytes in the upload packets, we feel this will not provide enough entropy to do our own encryption.”

“Sigfox does include encryption and many security mechanism.
See: https://www.sigfox.com/sites/default/files/1701-SIGFOX-White_Paper_Security.pdf

However these are handled by Sigfox and you only have 12 byte of data to play with.
You can code these 12 bytes as you like, but as the number of bytes are limited, it will be challenging to find an proper crypto algorithm.
