+# Generate self signed certificate with GnuTLS under Windows
+
+
+## 1. Install GnuTLS
+
+Download and decompress the Windows version of GnuTLS from [here](http://www.gnutls.org/download.html)
+
+Add the directory `gnutls-3.4.9-w64/bin` to your PATH environment and restart your console
+
+## 2. Generate private.key
+
+Run the following command to create `private.key`
+```
+certtool.exe --generate-privkey --outfile private.key 
+```
+
+## 3. Generate public.crt
+
+The easiest way is to generate certificate is to specify its information under a file. You can find an example below. We'll call that file `cert.cnf`.
+
+```
+# X.509 Certificate options
+#
+# DN options
+
+# The organization of the subject.
+organization = "Example Inc."
+
+# The organizational unit of the subject.
+#unit = "sleeping dept."
+
+# The state of the certificate owner.
+state = "Example"
+
+# The country of the subject. Two letter code.
+country = "EX"
+
+# The common name of the certificate owner.
+cn = "Sally Certowner"
+
+# In how many days, counting from today, this certificate will expire.
+expiration_days = 365
+
+# X.509 v3 extensions
+
+# DNS name(s) of the server
+dns_name = "localhost"
+
+# (Optional) Server IP address
+ip_address = "127.0.0.1"
+
+# Whether this certificate will be used for a TLS server
+tls_www_server
+
+# Whether this certificate will be used to encrypt data (needed
+# in TLS RSA ciphersuites). Note that it is preferred to use different
+# keys for encryption and signing.
+encryption_key
+```
+
+Now, it is time to generate the public certificate using this command:
+
+```sh
+certtool.exe --generate-self-signed --load-privkey private.key --template cert.cnf --outfile public.crt 
+```
+
+That's it.
