Bismillah,

Saat menggunakan password manager pass saya melihat bahwa salah satu GnuPG Key saya sudah expired.

abdullah@E202SA:~$ pass -c ssh/abdullah_key 
gpg: Note: secret key 840A4C6EXXXXXXXX expired at Tue 23 Sep 2025 10:21:04 AM WITA
Copied ssh/abdullah_key to clipboard. Will clear in 45 seconds.

Baik, saya cek dulu dengan kondisinya:

abdullah@E202SA:~$ 
abdullah@E202SA:~$ gpg --list-key abdullah@muntaza.id
pub   rsa3072 2020-08-16 [SC] [expired: 2025-09-23]
      55FB01545D893727472E1828E8CCFF0EXXXXXXXX
uid           [ expired] Abdullah <abdullah@muntaza.id>

Iya, ternyata memang expired, Kemudian, saya akan memperpanjang nya 1 tahun, dengan perintah “edit-key” seperti ini

abdullah@E202SA:~$ 
abdullah@E202SA:~$ gpg --edit-key abdullah@muntaza.id

Ketik expire, perpanjang 1 tahun dengan perintah 1y dan konfirmasi.

gpg: WARNING: Your encryption subkey expires soon.
gpg: You may want to change its expiration date too.

Kemudian, saya perpanjang juga subkey nya, ketik “key 1”, lakukan perintah expire dan perpanjang 1 tahun juga:

gpg> key 1

sec  rsa3072/E8CCFF0EXXXXXXXX

Langkah terakhir, ketik “save” untuk menyimpan.

gpg> save
abdullah@E202SA:~$

Saya cek bahwa GnuPG benar sudah di perpanjang:

abdullah@E202SA:~$ gpg --list-key abdullah@muntaza.id
pub   rsa3072 2020-08-16 [SC] [expires: 2026-12-12]
      55FB01545D893727472E1828E8CCFF0EXXXXXXXX
uid           [ultimate] Abdullah <abdullah@muntaza.id>
sub   rsa3072 2020-08-16 [E] [expires: 2026-12-12]

Demikian proses perpanjangan masa aktif GnuPG Key, semoga bermanfaat.

Alhamdulillah
