I check emails every 1-2 days.
First: Through Email
is a complete and free implementation of the OpenPGP standard as defined by RFC4880 (also known as PGP).
1. Import My Public Key
# fetch & import my public key
curl -sL https://deep-swarm.xyz/pgp.txt | gpg --import
# check this key
gpg --list-keys firstname.lastname@example.org
Note: alternative way:
gpg --search email@example.com, then check the fingerprint.
The fingerprint should be
2. Write Email
- open a text editor, Gnu Emacs
, write the text.
- find the path of this file, you'd better move it to a place, say: the
- find the filename your written email, say:
# enter into this folder
mkdir temp & cd temp
# the text.md here is the filename
gpg --encrypt --sign --armor -r firstname.lastname@example.org text.md
Then a file called:
text.md.asc will be generated.
Copy this encryped text to clipboard then paste to your written email page.
xclip -sel clip < text.md.asc
3. Attach Your Public Key For Me
- If you don't have a pgp/gpg public key, follow these steps:
# ---- then follow the interactive instruction ----
# select a type: choose (1) RSA and RSA
# select size: choose default, return
# set valid date, recommend 6 months: 6m
# Use a fake name, then return.
# then input your Email address
# then confirm: O
# then set a passphrase to protect your new key
## (save it in a safe place: KeePassXC)
Note: you can use this command:
openssl rand -base64 18 to generate random number for passphrase, and save it safely in keepassXC.
- Then export your public key as a txt file:
# export your public key
gpg --export --armor --output my_pubkey.txt <SELECT>
# check the path of this export file
Your public key's generated and you need to attach this txt file inside your email for me.
Send the email.

Fourth: Through Cwtch
You can first directly contact me through email, with or without gpg. Then we make an appointment to communicate through Cwtch.
Cwtch has a rule: If your contact is offline, messages can't be delivered. So we need to make an appointment in advance.
