Hi, I though this was already discussed, but I cannot find pointers.
When some entity verifies a certificate, finds a valid signature etc but the current date is not between "Valid From" to "Valid To", meaning the certificate seems "not yet valid" or "expired", what is recommended to do? I think, essentially, this should be application specific, but are there guide lines or common sense? In practice there could be issues with wrong sytem date / system clocks / time stamps, which could lead to bad situations, especially when users are not allowed to change the system date (for security reasons) and then failing to remotely administrate (because the peer rejects the actually valid certificate as "expired" or "not yet valid"). It cannot be assumed all entities are connected to the internet or any other external trusted time (except maybe an SSL protected one). Are there standards, recommendatations or any writings discussing such topics, in particular system date related topics? oki, Steffen About Ingenico: Ingenico is a leading provider of payment, transaction and business solutions, with over 15 million terminals deployed in more than 125 countries.
