Why isn’t PGP used to authenticate with keyservers?
OpenPGP can be used to sign messages / authenticate. Why is this not required by keyservers to ensure that only the owner of the private key can upload / modify / remove the public key on the server?
I understand that keys … Continue reading Why isn’t PGP used to authenticate with keyservers?
Is zero knowledge possible with webbased email services?
I’m presently using mailfence.com
They claim all encryption happen in the browser and that they are zero knowledge.
My question is this: Where do they store my key. If my private key is stored on their servers, can’t the… Continue reading Is zero knowledge possible with webbased email services?

How do I revoke my OpenPGP keys if I do not have access to my private key?
I have lost access to my PGP Private Key. However I still have the revocation certificate, the passphrase (and the public key).
Is it possible to revoke my key pair from the Public Key Servers using this information? If so, … Continue reading How do I revoke my OpenPGP keys if I do not have access to my private key?
Does GnuPG allow sub-sub-keys?
If subkeys are useful, does GnuPG have sub-sub-keys as well?
The current implementation of GnuPG feels a bit rigid, in that it only allows a two-level key management and subkeys are closely affiliated to their master key, ha… Continue reading Does GnuPG allow sub-sub-keys?
Can I encrypt with GnuPG and decrypt with OpenSSL?
I wonder why this does not work on Linux?
gpg –cipher-algo AES256 -c -o test.zip.enc test.zip
Enter passphrase:
openssl enc -AES-256-CBC -d -in test.zip.enc -out test.zip
enter aes-256-cbc decryption password:
bad magic number
To giv… Continue reading Can I encrypt with GnuPG and decrypt with OpenSSL?
OpenPGP key transition: strong RSA subkey under a weak DSA masterkey?
I have a DSA/ElGamal 1024/2048 OpenPGP key and want to migrate to a stronger set. I see two options but I’m unsure which is smarter.
keep DSA 1024 masterkey, generate 4096 RSA subkey
ditch the whole thing and generate a bra… Continue reading OpenPGP key transition: strong RSA subkey under a weak DSA masterkey?

How to raise a key to ultimate trust on another machine?
I have created a master key with two subkeys: one for signing and the other for encryption. Finally, I have exported the two subkeys to a new machine.
How can I tell the new machine to consider the master as “ultimate”, even if it is abse… Continue reading How to raise a key to ultimate trust on another machine?
