Information noteFor complete documentation, see the Microsoft New-SelfSignedCertificate documentation. The public key is used to encrypt the data and the private key is used to decrypt the data encrypted by the public key. Key encryption keys (KEK) are private and public key pair for secure, asymmetric encryption of the data encryption keys. A new key is generated for each object that is encrypted. The encryption solution uses two types of keys:ĭata encryption keys (DEK) are auto-generated keys for AES-256 encryption of the data. The key can be fetched even if the certificate has expired, and therefore there is no need to renew an expired encryption certificate. The encryption certificate functions as a shell around the encryption key. The certificates must be stored in a certificate store for the user running the QlikView Distribution Service (QDS). Encryption certificates overviewĮncryption keys are best managed through certificates. Older versions of Qlik Sense and QlikView returns an error when reading encrypted QVDs files. Information noteYou must reload an existing QVD for it to be encrypted after QVD encryption has been enabled in the settings.ini file. The engine then generates a new data encryption key (DEK) which is used to encrypt the data. #KEEP OLD FILE AFTER ENCRYPTO WINDOWS#The engine reads and then uses the thumbprint to get the key from the Windows CNG key store. QVD encryption is not enabled by default. The encryption is configured in the settings.ini file where encryption is enabled and the certificate thumbprint is added. The encryption keys are managed through certificates, that must be stored in a certificate store for the user running the QlikView Distribution Service (QDS). You can encrypt sensitive data in QVD files with customer supplied key pairs which allows you to control who gets access to your data.
