## Generate a TLS certificate
```
cd ~
go get -u -v github.com/lu4p/genCert
genCert --help
```
```
Usage of genCert:
-ca
whether this cert should be its own Certificate Authority
-duration duration
Duration that certificate is valid for (default 8760h0m0s)
-ecdsa-curve string
ECDSA curve to use to generate a key. Valid values are P224, P256 (recommended), P384, P521
-host string
Comma-separated hostnames and IPs to generate a certificate for
-rsa-bits int
Size of RSA key to generate. Ignored if --ecdsa-curve is set (default 2048)
-start-date string
Creation date formatted as Jan 1 15:04:05 2011
```
Example Certificate:
```
genCert --ca --ecdsa-curve P384 --host example.tld
```
This will result in the PrivateKey ```key.pem``` and the TLS-Certificate ```cert.pem```
Note: The PrivateKey should be kept PRIVATE, if the PrivateKey is disclosed an attacker is able to:
- imperson you
- decrypt your traffic
- etc.
