Creating self signed certificates with keytool

Content

1. Self signed certificate
2. Multiple domain names
3. Certificates for 2wayTLS
4. Certificate chain

NOTE: Do not use self signed certificates in PRODUCTION, for that use a certificate signed by some CA (Certification Authority), and then avoid man-in-the-middle attack.

'Twas the night before implementation and all through the house,
not a program was working not even a browse.
The programmers hung by their tubes in despair,
with hopes that a miracle would soon be there.

The users were nestled all snug in their beds,
while visions of inquiries danced in their heads.
When out in the machine room there arose such a clatter,
I sprang from my desk to see what was the matter.
