I had problems generating an OpenPGP key on my XUbuntu machine, because GnuPG did not get enough entropy. After some time of browsing and doing stupid stuff to generate more entropy, still nothing happened.
So I followed an … Continue reading Is my OpenPGP key rubbish because of bad entropy?
I’d like to be able to log into and out of my ssh servers freely without entering a password. Previously, I did this with ssh-keygen, storing the key file under my ~/.ssh directory.
Since I also have an OpenPGP key, I though… Continue reading Does it defeat the purpose to create an OpenPGP authentication subkey that is not password-protected?
Regarding to the second point of 15 reasons not to start using PGP:
Thanks to its easily detectable OpenPGP Message Format it is an easy exercise for any manufacturer of Deep Packet Inspection hardware to offer a detectio… Continue reading Is it possible to detect OpenPGP mails in TLS encrypted connections?
What is the common practice when a subkey reaches its expiration date?
Generate a new subkey
Pros
Increases security if the subkey has been stolen (without noticing) since Malory cannot use the old one anymore for futur… Continue reading Should I change my OpenPGP subkey, or just extend its expiration date?
I’m encrypting a file using the python-gnupg module like this. Ultimately, I want to use the AES256 cipher for encryption:
status = gpg.encrypt_file(fin, recipients=[‘root@frarakee’], output=’foo.bin.gpg’)
When I check the… Continue reading How can I tell what cipher was used by python-gnupg?

I am trying to set up my Yubikey 4 for GnuPGP following the Yubico documentation. I plugged in my Yubikey and it is recognized:
$ lsusb

However, when running any gpg2 co… Continue reading Setting up Yubikey for GnuPG on Linux Mint: Unsupported certificate
Recently, I have a need to encrypt few large files. I have the option to use the OpenSSL command line utility, however I prefer to use GnuPG.
How does GnuPG works under the hood with the –encrypt option?
Does it generate … Continue reading Does GnuPG use symmetric + public key encryption for large files?
