Introduction
Vault has the ability to encrypt binary files such as images. For safe transit, data must be transmitted to the Vault in the form of base64-encoded plaintext. Here we are using Transit Secret engine for encryption and decryption.
Prerequisites (if applicable)
- Vault
- Transit Secrets Engine (enabled)
- Required access to perform all necessary operations and Vault Token
- Install jq using for JSON data (Ex - snap install jq)
Information
- Encrypt/decrypt images using transit secret engine ( via CLI commands )
Steps to encrypt the image :
Once the transit secrets engine has been configured, any Vault client holding a valid token with the proper permissions can send any data to encrypt.
1. Convert image into base64 image
root@vaults0:/home/vagrant# base64 -w 0 absolute_path_of_image > base64_image.txt
example:-
root@vaults0:/home/vagrant# ls -ltr | grep -i flower_lily.jpg
#-rwxrwxr-x 1 root root 250366 Jul 13 09:12 flower_lily.jpg
root@vaults0:/home/vagrant# base64 -w 0 ./flower_lily.jpg > base64_image.txt
root@vaults0:/home/vagrant#
2. Run the command to store the encrypted value as an environment variable.
#Sending base64 converted image for encryption
#Here transit secret engine is already enabled at path /transit and key is created with name orders
root@vaults0:/home/vagrant# export CIPHERTEXT=$(vault write -format=json transit/encrypt/orders plaintext=@base64_image.txt | jq -r '.data | .ciphertext')
root@vaults0:/home/vagrant#
Steps to decrypt the image :
Any client holding a valid token with proper permissions can decrypt ciphertext generated by Vault. To decrypt the ciphertext, invoke the transit/decrypt
endpoint using the key which we used for encryption.
1. Decrypt the ciphertext emitted in the encrypt secrets step 2.
#Here we are decrypting the encrypted image that we did on above steps
root@vaults0:/home/vagrant# vault write -format=json transit/decrypt/orders ciphertext=$CIPHERTEXT > decrypt.json
root@vaults0:/home/vagrant# cat decrypt.json | jq -r '.data | .plaintext' > decrypt.txt
#For example it should look like this
root@vaults0:/home/vagrant# cat decrypt.txt
