What is a digital ID?
A digital ID is like an electronic driver’s license or passport that proves your identity. A digital ID usually contains your name and email address, the name of the organization that issued it, a serial number, and an expiration date. Digital IDs are used for certificate security and digital signatures.
Digital IDs contain two keys: the public key locks, or encrypts data; the private key unlocks, or decrypts that data. When you sign PDFs, you use the private key to apply your digital signature. The public key is in a certificate that you distribute to others. For example, you can send the certificate to those who want to validate your signature or identity. Store your digital ID in a safe place, because it contains your private key that others can use to decrypt your information
What are self-signed digital ID?
Self-signed digital IDs can be adequate for personal use or small-to-medium businesses. Their use should be limited to parties that have established mutual trust.
What are IDs from certificate authorities?
Most business transactions require a digital ID from a trusted third-party provider, called a certificate authority. Please contact IT Dept. if you require a Trusted ID certification to sign any business documents digitally.
