For more information, see [Supported versions](/apigee/docs/hybrid/supported-platforms#supported-versions).\n\n\nBy default, the following data is stored *encrypted* in the hybrid\nruntime plane:\n\n- Key management system (KMS) data\n- Key-value map (KVM) data\n- Cache data\n\n\nData encryption does not require any special configuration on your part. However, if\nfor some reason you want to use your own encryption keys (replacing the default ones) you can\ndo so, as explained in this topic.\n\nEncryption key scope\n--------------------\n\n\nEncryption keys for KMS, KVM, and cache have scope. For example, KMS keys have *organization*\nscope. This means that the key is used to encrypt KMS data for the entire organization.\nThe following table lists the scope for\neach type of key:\n\nAbout the default encryption keys\n---------------------------------\n\n\nBy default, Apigee hybrid provides a set of Base64-encoded keys that are used to\nencrypt KVM, KMS, and cache data. The Apigee hybrid installer stores the keys in the\nruntime plane as\n[Kubernetes\nSecrets](https://kubernetes.io/docs/concepts/configuration/secret/), and uses them to encrypt your data with AES-128 standard encryption.\nThe keys are under your control;\nthe hybrid management plane is never aware of them at any time.\n| The default keys will work for most use cases. If you want to change the default encryption keys, do so when you initially install Apigee hybrid into a new cluster. If you change the encryption keys after the runtime is created in your cluster, previously encrypted data can no longer work (it cannot be decrypted); only new data added after the change will be encrypted and function as expected.\n\nChanging the default encryption keys\n------------------------------------\n\n\nAlthough not required, you can change any of the default encryption keys if you wish.\nTo replace one or more default keys, follow these steps:\n| If you change the encryption keys after the runtime is created in your cluster, previously encrypted data can no longer work (it cannot be decrypted); only new data added after the change will be encrypted and function as expected.\n\n1. Copy the following stanzas into your overrides file. This configuration lets you change the KMS and KVM encryption keys for the organization level and the KVM and cache encryption keys for the environment level: \n\n ```\n defaults:\n org:\n kmsEncryptionKey: base64-encoded-key\n kvmEncryptionKey: base64-encoded-key\n env:\n kvmEncryptionKey: base64-encoded-key\n cacheEncryptionKey: base64-encoded-key\n ```\n2. Generate a new key for each key you wish to replace. Each key must be a Base64-encoded string that is exactly **16, 24, or 32 bytes long** . See also [How to create an encoded\n key](#how-to-create-an-encoded-key).\n3. Replace the default keys with new ones. In this example, all of the default keys are replaced with keys: \n\n ```\n defaults:\n org:\n kmsEncryptionKey: \"JVpTb1FwI0otUHo2RUdRN3pnVyQqVGlMSEFAJXYmb1c=\"\n kvmEncryptionKey: \"T3VkRGM1U3cpOFgtNk9fMnNZU2NaSVA3I1BtZWxkaUU=\"\n env:\n kvmEncryptionKey: \"Q3h6M3R6OWdBeipxTURfKjQwQVdtTng2dU5mODFHcyE=\"\n cacheEncryptionKey: \"b2NTVXdKKjBzN0NORF9XSm9tWFlYKGJ6NUhpNystJVI=\"\n ```\n4. Apply the overrides file to your cluster as follows:\n - If you change KVM or Cache keys, update only the environment: \n\n ```\n $APIGEECTL_HOME/apigeectl apply -f overrides/overrides.yaml --env env_name\n ```\n - If you change KMS keys, update both the org and environment: \n\n ```\n $APIGEECTL_HOME/apigeectl apply -f overrides/overrides.yaml --env env_name --org org_name\n ```\n\nA note about backward compatibility\n-----------------------------------\n\n\nIf you were to remove the encryption keys in your overrides file the first\ntime you install Apigee hybrid, you would\neffectively disable encryption and values would be stored unencrypted.\nIf at a later\ntime you enable encryption by providing keys,\nexiting data remains unencrypted; however, any future data that is added will\nbe encrypted. The system\nwill continue working normally with the unencrypted data and the new encrypted\ndata.\n\n\nAlso, note that\nyou cannot later change the encryption keys\nonce the runtime data is encrypted.\n\nHow to create an encoded key\n----------------------------\n\n| NOTE: You must generate your key from ASCII characters. Apigee hybrid does not support using non-printable characters, such as characters generated using the openssl random command.\n\n\nA properly formatted Base-64-encoded key is required for KVM, KMS, and cache encryption.\nThe key used for any of these purposes must be Base-64 encoded from a string that is 16, 24, or\n32 bytes long, as explained in the following steps:\n| The key string length requirement exists because the [Advanced\n| Encryption Standard](https://en.wikipedia.org/wiki/Advanced_Encryption_Standard) (AES) cipher works on a block size of 128 bits, but can take three different key lengths: 128, 192, and 256 bits (16, 24, or 32 bytes).\n\n\nThe following example commands generate suitable, randomly generated, 32 character,\nBase64-encoded strings that do not include non-printable characters: \n\n```\nLC_ALL=C tr -dc A-Za-z0-9_\\!\\@\\#\\$\\%\\^\\&\\*\\(\\)\\\\-+= \u003c /dev/urandom | head -c 32 | openssl base64\nPSFvX0BPc1Z2NVklcXdxcF8xR0N4MV4temFveStITU4=\n```\n\n\nor \n\n```\nLC_ALL=C tr -dc \"[:print:]\" \u003c /dev/urandom | head -c 32 | openssl base64\n```"]]
