Hiera-eyaml is a backend for Hiera which provides OpenSSL encryption/decryption for Hiera properties

Usage:
  eyaml [options] 
  eyaml -i file.eyaml       # edit a file
  eyaml -e -s some-string   # encrypt a string
  eyaml -e -p               # encrypt a password 
  eyaml -e -f file.txt      # encrypt a file
  cat file.txt | eyaml -e   # encrypt a file on a pipe

  EOS
