credkeep 0.2.1

Store credentials securely as ciphertext and decrypt on the fly with AWS KMS

credkeep

credkeep is a python package that helps ease the pain of storing sensitive credentials. Credentials that are securely encrypted using AWS’s Key Management Service (KMS) can be stored in version control systems where they cannot be decrypted without access to a users encryption key on KMS.

Installation

pip install credkeep

Usage

credkeep requires you to configure your own KMS master key. This key is used to encrypt/decrypt your data and is securely stored by AWS. Your KMS master keys can be viewed at https://console.aws.amazon.com/iam/home#encryptionKeys. For information about creating new master keys, see http://docs.aws.amazon.com/kms/latest/developerguide/create-keys.html.

Plaintext api secrets should not be stored in plain text. For example developer_secrets.json

{
    "SECRET_API_KEY": "thisismysecretkey",
    "ANOTHER_API_KEY": "anotherkey"
}

By calling credkeep.encrypt_file

{
  "SECRET_API_KEY": "CiAr4gKwrApZNibuqh1YKjlIGMj4A4GSHArF+0lCqBnqOxKfAQEBAgB4K+ICsKwKWTYm7qodWCo5SBjI+AOBkhwKxftJQqgZ6jsAAAB2MHQGCSqGSIb3DQEHBqBnMGUCAQAwYAYJKoZIhvcNAQcBMB4GCWCGSAFlAwQBLjARBAzGyPmdgqEbxzvnjKICARCAMzOd+DIaI/rUbc8dYQTxGS8aQQNjgXPt6Or0rxo7fFn0rA5/Kf6zpnui0q9XXtUatL4D3Q==",
  "ANOTHER_API_KEY": "CiAr4gKwrApZNibuqh1YKjlIGMj4A4GSHArF+0lCqBnqOxKXAQEBAgB4K+ICsKwKWTYm7qodWCo5SBjI+AOBkhwKxftJQqgZ6jsAAABuMGwGCSqGSIb3DQEHBqBfMF0CAQAwWAYJKoZIhvcNAQcBMB4GCWCGSAFlAwQBLjARBAxgB3p/zbVarLd/5a4CARCAK4w48/dCK7EvwTDELb11bpBe8TpaIhcCalfOqACQzoLoqgciAY8DuczOvRs="

This encrypted json file is safe to distribute via version control as it requires access to the master key on KMS. When the secrets in the file are required the file can be decrypted using credkeep.decrypt_file. This function can optionally set local environment variables with the decrypted secrets. These environment variables will not persist between shells or reboots.
