Responding to requests via simple route matching is built in to Go's net/http standard library package. Just register the path prefixes and callbacks you want invoked and then call the ListenAndServe to have the default request handler invoked on each request. For example:
package main
import (
| # Create your CA crt and key: | |
| openssl req -new -x509 -nodes -newkey rsa:4096 -extensions v3_ca -sha256 -days 3650 -subj "/C=US/ST=CA/L=San Francisco/O=Acme Inc./CN=Acme Insecure Certificate Authority" -keyout ca.key -out ca.crt | |
| chmod 600 ca.key | |
| # Create a CSR: | |
| openssl req -newkey rsa:2048 -nodes -sha256 -keyout cert.key -out cert.csr -subj "/C=US/ST=CA/L=San Francisco/O=Snakeoil Inc./OU=Core/CN=lobotomat.de" | |
| # Check contents of CSR (optional): | |
| openssl req -in cert.csr -text -noout |
