# Simple script to change all the passwords in the PE answer files.
# It should run from a directory containing the answer files.
# It will scan all .txt files looking for "q_.*password", generate a new
# password for each unique answer and replace the password on all files
# The console admin user password is hardcoded to "puppetlabs"

# Simple password generator
function pwgen {
  local l=$1
  local symbols=('0' '1' '2' '3' '4' '5' '6' '7' '8' '9' 'a' 'b' 'c' 'd' 'e' 'f' 'g' 'h' 'i' 'j' 'k' 'l' 'm' 'n' 'o' 'p' 'q' 'r' 's' 't' 'u' 'v' 'w' 'x' 'y' 'z' 'A' 'B' 'C' 'D' 'E' 'F' 'G' 'H' 'I' 'J' 'K' 'L' 'M' 'N' 'O' 'P' 'Q' 'R' 'S' 'T' 'U' 'V' 'W' 'X' 'Y' 'Z' '-' '_')
  local max=${#symbols[@]}
  local pass=""

  i=0
  while [ $i -lt $l ]
  do
    pass="${pass}${symbols[$[$RANDOM%$max]]}"
    ((i++))
  done
  echo ${pass}
}

regex="s:^q_puppet_enterpriseconsole_auth_password.*:q_puppet_enterpriseconsole_auth_password=puppetlabs:;"

for line in $(grep -h ^q_.*password *.txt|sed -e 's:=.*::' |sort -u )
do
  pass=$(pwgen 22)
  regex="${regex} s:^${line}.*=.*:${line}='${pass}':;"
done

sed -i.bak -e "${regex}" *.txt

Original version logic was less than optimal (and by less than optimal I mean I fucked up). It was overwriting the .bak once for each password. So the .bak files were useless.

Now it should work as expected.

The console password is hardcoded to puppetlabs now and you are going to change it anyway (you ARE going to change it, right?)
