WhisperKey

Try WhisperKey free for 30 days. Encrypt messages before you send them in WhatsApp, Signal, iMessage, and more. Subscribe after your trial to keep encrypting.

WhisperKey is free to download and adds an extra layer of encryption to messages you send in apps you already use—like WhatsApp, Signal, iMessage, SMS, Teams, Slack, and email. Type in WhisperKey, encrypt, then share or copy into any messaging app.

HOW IT WORKS Open the Compose tab and type your message. Choose an encryption mode: Open, WhisperKey, or a paired contact. Tap Encrypt. Tap Share or Copy and send it through your favorite messaging app. When you receive an encrypted message, paste it into Compose, choose the same mode, and tap Decrypt.

ENCRYPTION MODES • Open — send plain text with no encryption. • WhisperKey — encrypt so any WhisperKey user can decrypt. No setup required. • Private — pair with a contact using a shared phrase. Only you and that contact can decrypt each other’s messages.

PAIRING Create or share a pairing phrase with someone you trust. Both users save the phrase, verify that the generated verification code matches, and complete pairing. Verified contacts appear in the encryption mode menu.

PRIVACY All encryption and decryption are performed locally on your device. WhisperKey does not store your messages, pairing phrases, or decrypted content on external servers. Shared pairing information is protected using Apple’s secure Keychain technology.

FREE 30-DAY TRIAL New users receive a free 30-day trial with full access to encryption and decryption in Compose. No subscription is required during the trial. After the trial ends, WhisperKey Annual ($9.99/year) is required to continue using Encrypt and Decrypt. You can still browse the app, manage contacts, and use the tutorial without a subscription.

SUBSCRIPTION WhisperKey Annual unlocks continued access to encryption and decryption after the free trial. Subscribe, restore purchases, or manage your plan in Settings.
