Digital Signatures
QNAP uses digital signatures to validate apps created by QNAP or QNAP-trusted publishers. The use of
digital signatures prevent the unauthorized tampering of apps that may lead to security risks.
A digital signature is considered valid if it meets the following criteria.
• The digital signature has not been tampered with.
• The digital signature has not expired.
• The digital signature is certified by QNAP.
Enabling Installation of Apps without Digital Signatures
Warning
• A valid digital signature ensures that an application was created by QNAP or a QNAP-
trusted publisher. It also ensures that the app has not been maliciously tampered with.
Installing apps without valid digital signatures may expose your NAS to security risks.
QNAP shall not be held liable for any damages, data loss, or security vulnerabilities
resulting from the installation and use of such apps.
