Hi, I was wondering whether the GNU core utility Shred is capable of performing the various secure deletion modes such as the military standard mode (DoD), NSA, and Guttman. I know you can specify the number of passes it performs, but is it possible to put these algorithms put in effect at all? If not, is there a free command line utility / C/C++ API that I can use to perform those secure deletion modes on Linux? I'm trying to do this programatically. Thanks.
