how to create cert with a bigger validity using pyndnsec

[killerdbob]

Hi, I would like to ask while I was using pyndnsec New-Item /pcnl/ndn/video/sz02/live, the 'NotAfter' filed seems only have +1 day of validity, and I don't see an option for pyndnsec to prolong it.

• /pcnl/ndn/video/sz02/live +-> /pcnl/ndn/video/sz02/live/KEY/-F%96%1F%40%04%2F%05 +-> /pcnl/ndn/video/sz02/live/KEY/-F%96%1F%40%04%2F%05/self/v=1649990055921 Certificate name: /pcnl/ndn/video/sz02/live/KEY/-F%96%1F%40%04%2F%05/self/v=1649990055921 Validity: NotBefore: 19700101T000000 NotAfter: 20220415T023415 <------------------- out of date Public key bits: MFkwEwYHKoZIzj0CAQYIKoZIzj0DAQcDQgAE1h+7WRmW8/n7lJ6cfyMaDiGdYqQH 9EFjUc5Df1e9RbmtjIXbPLRiCxTC5Dbyh/TY59YvOV8IEQRQQU30t4Y/Dw== Signature Information: Signature Type: SignatureSha256WithEcdsa Key Locator: /pcnl/ndn/video/sz02/live/KEY/-F%96%1F%40%04%2F%05

Thank you for reporting this. This is a bug and I have fixed it.

so, how do I prolong the validity? or should I use python-ndn v3.1?

You need to delete the certificate and create a new one. You can use the latest pyndnsec (not published so you need to install from GitHub) or ndnsec.
