I recently read about OpenGPG cards, hardware tokens that support authentication and encryption. They are usually smartcard-based, but USB-based tokens also exist (for example, Nitrokey and YubiKey).
My laptop has an “SD-MMC… Continue reading Is there an OpenGPG hardware token for an SD-MMC slot? [on hold]
I frequently use GPG to verify downloads. By doing that I implicitly put trust in a key provided by the author. At least I trust the key enough to run software verified using the given key on my computer. Some examples might … Continue reading Is it responsible to sign an OpenPGP key without verifying person’s identity?
If a signature was made before the key was revoked will it still be considered as valid after revocation? Assuming that the key was revoked as superseded, the answer is obvious if the key was compromised.
In particular I’m i… Continue reading Is an OpenPGP signature made before a key is revoked considered valid?
Encryption is one of the pillars of modern-day communications. You have devices that use encryption all the time, even if you are not aware of it. There are so many applications and systems using it that it’s hard to begin enumerating them. Ranging from satellite television to your mobile phone, from smart power meters to your car keys, from your wireless router to your browser, and from your Visa to your Bitcoins — the list is endless.
One of the great breakthroughs in the history of encryption was the invention of public key cryptography or asymmetrical cryptography in the 70’s. …read more
GnuPG offers a set of different trust models, but the manual isn’t sufficient (for me at least) to figure out which one to use.
Ideally, I would like a trust model that accepts the trust I explicitly assign to a key using Gn… Continue reading How should I choose a trust model in GnuPG?
Here is context:
I am using PGP to encrypt messages in a chat web app. After going through some articles, I get brief idea how PGP works and here is how I am doing it with openPGPJs :
Client(web browser) generate the public/private key-pa… Continue reading PGP encryption for the server based app
I was wondering if anyone has any recommendations for getting my OpenPGP key signed by others. I live in the middle of nowhere, and there aren’t meetup groups within 50 miles of me ever.
How to get my key signed by people, a… Continue reading How to get my OpenPGP keys signed?
I have a few text files (private keys of crypto currency wallets) that I have encrypted with GPG/openpgp.
I have additionnaly encrypted the private key that I used for this in zip file.

I generated a key pair with GPG Tools for Mac and exported the public and private key to a safe place.
I assume that I can decrypt my stuff with this USB in any OS (e.g. Linux) and any GnuPG software.
Is that correct?
… Continue reading Are GPG Tools Keys Just Plains GnuPG Keys?
I had two OpenPGP key files on two separate TAILS OS USB flash drives, but the most recent one fails to boot up. Then I discovered that I don’t remember the old keys passphrase on the first USB flash drive.
I still can export the private … Continue reading Forgot OpenPGP key’s passphrase, can I recover key or files somehow?
