#6517 closed Bug report (rejected)

Certificate expired! (v3.3.5.1)

Reported by: Owned by:
Priority: low Component: FileZilla Client
Keywords: Cc:
Component version: Operating system type: Windows
Operating system version: XP Pro SP3


Doing an FTPES connection to (with any random username and password) gives a "Unknown certificate" message which says that the certificate expired in 01/01/1970 !!!

Is the certificate faulty, or FileZilla ?

By the way, this is the same certificate mentioned in bug #5693
so it's possible that those code changes caused the problem.

Definitely a broken certificate.

I have attached the decoded certificate. The notAfter field of the certificate is:

<P O="211" T="[UNIVERSAL 24]" TL="2" V="15" A="GeneralizedTime">19020219092442Z</P>

According to RFC 2459 which defines the structure of the certificate, the GeneralizedTime of the notAfter MUST be encoded according to YYYYMMDDHHMMSSZ.


This clearly shows that the certificate has expired over a hundred years ago.
