Creating digital IDs
If you're not using a third-party digital ID, you can create your own self-signed digital ID.
The resulting file stores an encrypted private key used for signing or decrypting
documents, and a public key contained in a certificate, which is used for validating
signatures and encrypting documents.

You can create either a PKCS#12 digital ID, which is a standard encryption format, or a
Windows Default Certificate digital ID, which is stored in the Windows Certificate Store.
PKCS#12 file extensions are .pfx in Windows and .p12 in Mac OS.

RSA, but 1024-bit RSA is more universally compatible.
8. From the Use Digital ID menu, choose whether you want to use the digital ID for digital
