PGP Encrypt Message

Encrypt text messages using PGP/GPG public keys for secure communication and data protection.

Overview

PGP Encrypt Message lets you encrypt any text using a recipient's PGP/GPG public key and produce standard ASCII-armored ciphertext (.asc) ready to paste into an email or any other channel. The entire OpenPGP operation runs inside your browser — your plaintext message and the recipient's public key are processed locally and never sent to a server. You can add multiple public keys at once to produce a single ciphertext that each intended recipient can independently decrypt with their own private key. No account, no installation, and no file upload required.

Common Use Cases

  • Secure Email Communication — Encrypt sensitive messages before pasting them into email so only the intended recipient — holding the matching private key — can read them.
  • Confidential File Transfers — Wrap confidential text content (API keys, credentials, legal text) in PGP encryption before transmitting over insecure channels like Slack or shared drives.
  • Multi-Recipient Encryption — Encrypt a single message to multiple colleagues by importing each person's public key, so every recipient can decrypt independently without sharing a password.
  • Offline / Air-Gapped Use — Because the tool works fully offline, you can load the page, disconnect from the internet, and encrypt sensitive messages on an air-gapped machine.
  • PGP Workflow Testing — Developers and security engineers can quickly test public-key distribution and encryption round-trips without setting up a local GPG installation.

How It Works
1

Import Recipient's Public Key

Upload or paste the PGP public key of the person you want to send an encrypted message to.

2

Enter Your Message

Type or paste the text message you want to encrypt. The message can be any length of text content.

3

Encrypt and Share

The tool encrypts your message using the recipient's public key. Copy the encrypted text to send via email or other channels.

Frequently Asked Questions

How does PGP message encryption work?
PGP uses the recipient's public key to encrypt messages that only their private key can decrypt. This ensures only the intended recipient can read your message.

Do I need the recipient's private key?
No, you only need their public key to encrypt messages. They use their private key to decrypt and read your message.

Can I encrypt messages to multiple recipients?
Yes, you can add multiple public keys to encrypt the same message for several recipients. Each person can decrypt it with their own private key.

Is the encryption process secure?
Yes, all encryption happens locally in your browser. Your message and the recipient's public key are never transmitted to external servers.

What if I don't have the recipient's public key?
You need to obtain their public key first. They can share it via email, key servers, or generate one using our PGP key generator tool.
