cloud-assisted file encryption software? I don't think adding that buzzwords is clever from a PR point of view. Or is it just me who associates cloud with privacy and security problems?

DON'T use for strong crypto till there's been a cryptanalysis from a reputable expert. SCTR, never heard of it. Probably we never will.

I can promise everyone $50,000 too as long as I stay anonymous, see their PrivacyProtect whois entry and anonymous email contact.

 

I don't like it. They give zero information about the ciphers used. All we know is it uses a "512 bit symmetric block cipher" which is not standard (I am not aware of any 512 bit block ciphers being a part of any recognized crypto standard). They also do not provide source code which is a big red flag.

 

that's what makes me wonder..
