Descriptions
The goTenna Pro series does not use SecureRandom when generating its cryptographic keys. The random function in use is not suitable for cryptographic use.
The goTenna Pro App does not use SecureRandom when generating passwords
for sharing cryptographic keys. The random function in use makes it
easier for attackers to brute force this password if the broadcasted
encryption key is captured over RF. This only applies to the optional
broadcast of an encryption key, so it is advised to share the key with
local QR code for higher security operations.
