I use this function to determine who accessed any database program (and therefore its dbfs) , and sets the authority level so only I can see the good stuff :) and it also decrypts the necessary dbf files with an external encryption program using aes256.

Are there legal minimum requirements for security?

Also unless all your DBF files are encrypted too it's kind of redundant.

Thanks. I read the pdf only to find that he referenced a hash method that I am using (salted 2007 without going farther on an open forum). Unfortunately, the .fll file is compiled and I cannot see the source code to determine if it is using visual foxpro only code, or functions that are available in fpdos 2.6. This is what I use so I can run under ubuntu/dosemu or my true dos partitions. When I bought vpf 5.0 years ago, there was a 'not enough ram' error that friends were also having. It had something to do with the fact that I had excessing ram and vfp calced the ram to not enough. I was unable to find a solution and vfp did not seem to run reliably under linux/wine do I stayed with dos. I am no praying with gambas and pure basic,

I am currently using some code that I acquired years ago to hash (1 way encrypt) passwords. Now I am wondering if it is sufficient for the use. Is there either a foxpro (.prg) source that I can incorporate into my log on program or binary that I can load into memory? This is for my alarm company dispatch center, so i have a responsibility to be secure.

I'm sorry, John, I missed the "fox/dos" in the message title.

You may want to contact Craig Boyd, the proprietor of Sweet Potato Software, to determine if he can supply you with a .PLB (the DOS equivalent of FLLs).

A quick search for "Password Hash in DOS" fails because of "Denial of Service" and "Dos and Don'ts" filling the list...
