I am in the process of learning PGP (GnuPG more precisely).
I am trying to figure out which is the best strategy for my encryption ([E]) subkey in terms of expiration/revocation/renewal. Could you please tell me if the following affirmatio… Continue reading PGP expired encryption subkey : renew or replace?
How do I indicate that a specific document or transaction associated with a particular signature should no longer be considered valid?
I’m talking of recalling a signed document, not revoking the private key, because with the private key I… Continue reading Revoking a digital signature at the cryptographic level
I am planning on making a basic groupchat application only for me and my colleagues. It needs to be as secure and anonymous as possible without leaving any fingerprints. Already existing applications cannot be trusted.
This is how I would … Continue reading Implementing a anonymous encrypted peer-to-peer chat [closed]
I’ve been able to locate http://www.aaronsw.com/2002/draft-swartz-pgp-urn-00, but it appears to be an unofficial proposal never submitted to the IETF. Does it hold any water?

Sometime back I installed GPG and been using it to encrypt files and text.
Command used to encrypt:
gpg -c file.zip > file.zip.gpg
Command used to decrypt:
gpg -d file.zip.gpg > file.zip
Till now, I didn’t pay attention to which ke… Continue reading GPG: Which key is gpg exactly using for encrypting and decrypting? [migrated]
I came across a PGP public key that seems invalid. The key is a secp256k1 public key that supported by GPG. In fact, GPG allows importing that key even if it has an invalid secp256k1 public key inside.
Running –list-packets on the key sho… Continue reading GPG allows importing an invalid secp256k1 public key
Eleptial Curve is now included in PGP. However when I run gpg2 –full-gen-key, I get
Please select what kind of key you want:
(1) RSA and RSA (default)
(2) DSA and Elgamal
(3) DSA (sign only)
(4) RSA (sign only)
(14) Existing… Continue reading Why is ECC (Eliptical Curve) an `–expert` feature in PGP?
If we are self hosting our own email server with mydomain.com with a self sign CA for S/MIME. What are some possible ways that our email content can get leaked?
Then if we use PGP email, does it make any difference? Since we agree that wit… Continue reading With selfhosting email server, selfsigned certificate, does it make a difference with PGP mail, What can be leaked?
In order to keep all my secret in the same place, I would like to store my GPG private key in KeePassXC, under the "Notes" field.
Provided that the db file has very good password, is this safe?
Os this field encrypted?
What is the most secure way and privacy-focused to send email now (current tech)? PGP or S/MIME, Given both parties willing to learn the technical parts?
Use case, both of parties use third party email services, like gmail/hotmail/proton… Continue reading What is the most secure way to send email now? PGP or S/MIME, Given both parties willing to learn the technical parts
