When signing with XolidoSign Desktop appears "Algorithm specified is not valid"

When performing a signature process, there are several options for calculating the summary function HASH of the file to be signed. By default, following the latest safety recommendations SHA-256 is used.

Some devices or enviroments, such as your cryptographic card, are incompatible with some advanced HASH algorithms. In these cases, we recommend using SHA-1 algorithm.

To do this you must access in XolidoSign Desktop to Sign -> Options -> Configuration F5 -> Advanced options

In this option, choose SHA-1. Lastly, Apply the changes and Accept.
