VeraCrypt audit[edit]

QuarksLab conducted an audit of version 1.18 on behalf of the Open Source Technology Improvement Fund (OSTIF), which took 32 man-days. The auditor published the results on 17 October 2016.[14][23][24] On the same day, IDRIX released version 1.19, which resolved major vulnerabilities identified in the audit.[25]

Fraunhofer Institute for Secure Information Technology (SIT) conducted another audit in 2020, following a request by Germany's Federal Office for Information Security (BSI), and published the results in October 2020.[26][27]
