golang encyrpt, decrypt key with kms
/*
The code below shows how to encrypt and then decrypt some plaintext into a cyphertext using
KMS's Encrypt/Decrypt functions and secretbox (https://godoc.org/golang.org/x/crypto/nacl/secretbox).
The plaintext message is sealed into a secretbox using a key that is generated by kmsClient.GenerateDataKey().
Note that this procedure reuquires that a master key would *already exist in KMS* and that its arn/alias is specified.
The aws library assumes that the proper credentials can be found in the shared file (~/.aws/credentials)
and opts for the 'default' role.
Once sealed, the cyphertext is then unboxed, again by first getting the key from kms (kmsClient.Decrypt),

Set up kerberos on Redhat/CentOS 7

Installing Kerberos on Redhat 7

This installation is going to require 2 servers one acts as kerberos KDC server and the other machine is going to be client. Lets assume the FQDN's are (here cw.com is the domain name, make a note of the domain name here):

  • Kerberos KDC Server: kdc.cw.com
  • Kerberos Client: kclient.cw.com

Important: Make sure that both systems have their hostnames properly set and both systems have the hostnames and IP addresses of both systems in
