Generating secrets for applications

Using Python and Terminal:

python -c 'import secrets; print(secrets.token_urlsafe(16))'

python -c 'import secrets; print(secrets.token_hex(16))'

If for some of you on Windows does not work, replace single quotes ' into double quotes ".

Using OpenSSL:

openssl rand -base64 16

openssl rand -hex 16

The number you choose is the length of the secret in bytes, a hex of 16 bytes will produce 32 character strings.
