Let's simplify your question to the above.
The answer is no.
Truecrypt is no longer maintained, and at least two serious flaws have been found.
Windows users who rely on TrueCrypt to encrypt their hard drives have
a security problem: a researcher has discovered two serious flaws in
the program.
TrueCrypt may have been abandoned by its original developers, but it
remains one of the few encryption options for Windows. That keeps
researchers interested in finding holes in the program and its
spin-offs.
James Forshaw, a member of Google's Project Zero team that regularly
finds vulnerabilities in widely used software, has recently discovered
two vulnerabilities in the driver that TrueCrypt installs on Windows
systems.
The flaws, which were apparently missed in an earlier independent
audit of the TrueCrypt source code, could allow attackers to obtain
elevated privileges on a system if they have access to a limited user
account.
The original authors of TrueCrypt, who have remained anonymous,
abruptly shut down the project in May 2014 warning that "it may
contain unfixed security issues" and advised users to switch to
BitLocker, Microsoft's full-disk encryption feature that's available
in certain versions of Windows.
...
Since TrueCrypt is no longer actively maintained, the bugs won't be
fixed directly in the program's code. However, they have been fixed in
VeraCrypt, an open-source program based on the TrueCrypt code that
aims to continue and improve the original project.
VeraCrypt 1.15 that was released Saturday, contains patches for the
two vulnerabilities, identified as CVE-2015-7358 and CVE-2015-7359, as
well as for other bugs. The program's developer only flagged the
CVE-2015-7358 flaw as critical and said that it can be exploited by
"abusing drive letter handling."
...
Users who still use TrueCrypt should switch to VeraCrypt as soon as
possible. In addition to patches for these two flaws, the program also
has other security improvements over its predecessor.
