Before installing SuprSend, you need to generate three essential
keys for your deployment. These keys ensure secure communication and
encryption between different components of SuprSend.
Generate Deployment Secret Key
This key is a unique random string used to authenticate and secure your
SuprSend installation.
Run the following Python script to generate a strong secret key:
Then, in the interactive shell:
import secrets
"".join(secrets.choice("abcdefghijklmnopqrstuvwxyz0123456789!@#$%^&*(-_=+)") for i in range(50))
x2#e9ahb!@1d3f_4g5jklmn6opq7rstuv8wxyz
Keep this key private. It should never be committed to version control or shared publicly.
Generate NATS NKey Pair
SuprSend uses NATS as its internal messaging backbone.
You’ll need to generate a public/private key pair for secure message
signing and validation.
-
Install the
nk CLI tool for generating NATS keys:
go install github.com/nats-io/nkeys/nk@latest
-
Generate a new user key pair:
You’ll get two keys: - Private Key → starts with SU... - Public
Key → starts with U... Example output:
SUAGC2U8QYUZ7A... (Private Key)
UAGB2UZJBNFJZ3... (Public Key)
- Store the private key securely — it must not be exposed or shared.
- The public key can be shared with your SuprSend deployment configuration.
Generate AES Cipher Secret and Vector
SuprSend uses AES encryption for sensitive payloads.
You’ll need to generate a shared AES key and an initialization
vector (IV).
Run the following Python script:
Then, inside the interactive shell:
def aes_cipher():
import os
shared_secret = os.urandom(32)
iv = os.urandom(16)
print("Shared Secret (AES Key):", shared_secret.hex())
print("Vector (IV):", iv.hex())
aes_cipher()
Shared Secret (AES Key): `3f2a9e5b1d0a6c4d4e7f9b1c2d3a4b5c6d7e8f90123456789abcdef1234567890`
Vector (IV): `1a2b3c4d5e6f70819283746556473829`
Save both values safely. They’ll be required in your SuprSend configuration under encryption settings.
