I have a worksheet where I need to lock two specific ranges of cells with two different digital signatures. Essentially, one person will enter data and sign and then the file will be sent to another for more data entry that will also need to be signed. So far, I haven't been able to use the digital signature except to convert the entire workbook to Read-Only.

You can only currently use a digital signature on an entire workbook or a macro project, not a range
