How to Send an Encrypted Message

Option 1: Use aliceandbob.io(easiest)

  1. Go to aliceandbob.io/online-pgp-tool
  2. Paste the public key above into the "Recipient's Public Key" field
  3. Type your message and click Encrypt
  4. Copy the encrypted output and email it to seqrets@proton.me

aliceandbob.io runs entirely in your browser — nothing is sent to any server.

Option 2: GPG Command Line

# Download and import the key
curl -sO https://seqrets.app/pgp.txt
gpg --import pgp.txt

# Encrypt a message
echo "Your secret message" | \
  gpg --encrypt --armor \

  document.pdf

Send the encrypted output (.asc) as an email or attachment to seqrets@proton.me.

Option 3: Email Clients

Thunderbird

Built-in OpenPGP support. Go to Settings → End-to-End Encryption → OpenPGP Key Manager → Import. Then compose to seqrets@proton.me and click the encrypt button.

Apple Mail

Install GPG Suite, import the key, then compose normally — it auto-encrypts when a recipient key is available.

Outlook (Windows)

Install Gpg4win with Kleopatra, import the key, then use the GpgOL plugin to encrypt from Outlook.

Proton Mail users: messages sent to seqrets@proton.me from another Proton account are end-to-end encrypted automatically — no extra steps needed.
