encryption – Is SECCURE (still) safe enough for public backups

I recently came across the SECCURE tools for simple encryption of data, but I’m uncertain about how up to date their security is. On the page the author says that the tools have been audited by Ulf Harnhammar and Brian M. Carlson of the Debian auditing team in august 2006, but both links to the audits are dead and 2006 is a long time ago anyway.

Does someone know about other (maybe more recent) security audits of SECCURE or has any other indication of its suitability for backup encryption in 2020?
