Digital Envelope
Not started
A digital envelope uses symmetric encryption for large documents (because it is fast) and public key cryptography to encrypt and send the symmetric key — combining the strengths of both methods.
- Define a digital envelope.
- Explain why digital envelopes combine symmetric and public key methods.
- Describe the steps of creating and opening a digital envelope.
- Identify the advantage of digital envelopes over either method alone.
