Full Title or Meme
Certificates and Credentials typically include an Expiry date-time or event, such as "on first use".
Context
- Many digital documents include a start data and an Expiry date.
- Many digital documents include a nonce or serial number which typically is used to ensure that the document is only processed on time, and then expires.
Problems
Expiry can be devilishly difficult to determine.
- Typically, a Certificate will expire on a give data and time, which seems very clear.
- When a key with a certificate is used to sign a document, should the data of validation or the date of signing be operative?
