Digital IDs

Nitro PDF Pro for Windows

 A Digital ID is used to verify your identity and secure PDF files.

You can use a Digital ID to:

    • Create digital signatures
    • Encrypt PDF files
    • Control access and usage rights per user
    • Validate document authenticity

A Digital ID includes a public key and a private key.

    • Public key: Contains certificate and identity information. You share it with other users
    • Private key: Remains secure and is never shared. It is used to decrypt files and apply signatures

How Digital IDs work

    • Users share public keys
    • Public keys are used to encrypt documents
    • Only the matching private key can decrypt the document
    • This protects document integrity and access
