Pengantar

Cloud KMS adalah layanan pengelolaan kunci kriptografi di Google Cloud. Sebelum menggunakan KMS, Anda harus mengaktifkannya di proyek Anda. Di lab ini Anda telah disediakan KMS yang seharusnya sudah diaktifkan. Anda dapat memastikannya dengan menggunakan salah satu perintah gcloud CLI. Jalankan yang berikut ini di sesi Cloud Shell Anda:

Buat Cloud Storage bucket

Jalankan cloud shell berikut

BUCKET_NAME=<YOUR_NAME>_enron_corpus

Buat Bucket

gsutil mb gs://${BUCKET_NAME}

Check out the data

Download local

gsutil cp gs://enron_emails/allen-p/inbox/1. .

tail download

tail 1.

Enable Cloud KMS

gcloud services enable cloudkms.googleapis.com

Buat Keyring dan Cryptokey

KEYRING_NAME=test CRYPTOKEY_NAME=qwiklab

Buat keyring

gcloud kms keyrings create $KEYRING_NAME --location global

Buat cryptokey

gcloud kms keys create $CRYPTOKEY_NAME --location global \
      --keyring $KEYRING_NAME \
      --purpose encryption

Buka Navigation menu > Security > Key management:

Encrypt Your Data

PLAINTEXT=$(cat 1. | base64 -w0)

encrypt key

curl -v "https://cloudkms.googleapis.com/v1/projects/$DEVSHELL_PROJECT_ID/locations/global/keyRings/$KEYRING_NAME/cryptoKeys/$CRYPTOKEY_NAME:encrypt" \
  -d "{\"plaintext\":\"$PLAINTEXT\"}" \
  -H "Authorization:Bearer $(gcloud auth application-default print-access-token)"\
  -H "Content-Type: application/json"

save file

curl -v "https://cloudkms.googleapis.com/v1/projects/$DEVSHELL_PROJECT_ID/locations/global/keyRings/$KEYRING_NAME/cryptoKeys/$CRYPTOKEY_NAME:encrypt" \
  -d "{\"plaintext\":\"$PLAINTEXT\"}" \
  -H "Authorization:Bearer $(gcloud auth application-default print-access-token)"\
  -H "Content-Type:application/json" \
| jq .ciphertext -r > 1.encrypted

cek decrypt

curl -v "https://cloudkms.googleapis.com/v1/projects/$DEVSHELL_PROJECT_ID/locations/global/keyRings/$KEYRING_NAME/cryptoKeys/$CRYPTOKEY_NAME:decrypt" \
  -d "{\"ciphertext\":\"$(cat 1.encrypted)\"}" \
  -H "Authorization:Bearer $(gcloud auth application-default print-access-token)"\
  -H "Content-Type:application/json" \
| jq .plaintext -r | base64 -d

upload encrypt file ke bucket

gsutil cp 1.encrypted gs://${BUCKET_NAME}

Configure IAM Permissions

authorize user

USER_EMAIL=$(gcloud auth list --limit=1 2>/dev/null | grep '@' | awk '{print $2}')

assign IAM permission

gcloud kms keyrings add-iam-policy-binding $KEYRING_NAME \
    --location global \
    --member user:$USER_EMAIL \
    --role roles/cloudkms.admin

assign cryptokey

gcloud kms keyrings add-iam-policy-binding $KEYRING_NAME \
    --location global \
    --member user:$USER_EMAIL \
    --role roles/cloudkms.cryptoKeyEncrypterDecrypter

Back up data on the Command Line

copy email

gsutil -m cp -r gs://enron_emails/allen-p .

Copy ke bucket

MYDIR=allen-p
FILES=$(find $MYDIR -type f -not -name "*.encrypted")
for file in $FILES; do
  PLAINTEXT=$(cat $file | base64 -w0)
  curl -v "https://cloudkms.googleapis.com/v1/projects/$DEVSHELL_PROJECT_ID/locations/global/keyRings/$KEYRING_NAME/cryptoKeys/$CRYPTOKEY_NAME:encrypt" \
    -d "{\"plaintext\":\"$PLAINTEXT\"}" \
    -H "Authorization:Bearer $(gcloud auth application-default print-access-token)" \
    -H "Content-Type:application/json" \
  | jq .ciphertext -r > $file.encrypted
done
gsutil -m cp allen-p/inbox/*.encrypted gs://${BUCKET_NAME}/allen-p/inbox
