[Cryptography] A two key file/program

[Allen Schaaf]

Hi folks,

I'm looking for a program or file system to run on Windows 
7/8.1/10 to keep data protected that requires two separate keys 
used at the same time to open the file. It needs to be like the 
missile launching system that was created using two physical keys 
at the same time to prevent one crazy person from starting a war.

The goal for the credit union is to encrypt login information 
used by the staff.

Each of the staff has six or seven user names and passwords for 
various local and remote systems. The manager/CEO and assistant 
manager need to enable access to each account when either there 
is a potential problem or when they are not available. One 
example of this need is that US law requires each employee to 
take a minimum one week vacation so that any fraudulent behavior 
will be interrupted and also that the transaction they did can be 
audited without them overseeing the audit process.

I recall that there is a system like this but I'm unable to find 
it. Given that it is a very small credit union and that it 
functions in a lower income market it would be best if it was 
free or low cost.

I'm President of the BoD and the primary tech support person in 
my retirement.

Thanks,

Allen
