How to Generate Random Secret OpenSSL
- Ashik Nesin
Whenever we work on a new project, we might need to generate a random secret for our projects like for example JWT secret which is used to sign the token or any other auth tokens.
Sure, we can generate it online using various apps but if you've security/privacy concerns and want to generate locally then OpenSSL might be a good choice for you.
If you don't have OpenSSL already in your machine, you can install it using various methods.
brew install openssl
And for others, you can refer to their docs
Generate random secrets
rand command which we'll be using to generate secrets
The usage of it is like this:
# num -> length openssl rand [-base64 | -hex] [-out file] num
Generate random base64 secrets
openssl rand -base64 12 # dfzpJRkPLAguzfRQ
Generate random hex secrets
openssl rand -hex 12 # 56705a986f27b8e9f8857ec1
Happy generating secrets!
