# AESKey

The AES key to use for Knowledge Discovery data encryption.

Setting this parameter or AESKeyFile turns on encryption for your View component cache. If you change the encryption key, any existing encrypted documents that are stored in the cache become inaccessible and are deleted.

NOTE: You cannot set both `AESKey` and AESKeyFile.

You can use this option to import a key directly from a secret source, such as an environment variable or HashiCorp Vault. See Include a Value from an Environment Variable and Import a Value from an External Source.

The key protects access to your encrypted data, so OpenText strongly recommends that you do not to supply it as a plain text configuration value. Setting a plain text value returns a configuration validation error, but does not prevent the server from starting up.

NOTE: You can also enable encryption by using the `-dataencryptionkey` command line parameter when you start the View component. If you use this option, it overrides the `AESKey` setting.

Type: | String
Default: |
Required: | No
Configuration Section: | DataEncryption
Example: |
    < :HASHICORPVAULT [VaultSettings] KDDataEncryptionAESKey : AESKey
This example imports the value of the `KDDataEncryptionAESKey` parameter in your HashiCorp Vault as the AES encryption key for data encryption.
