Workflow

1. Encrypt Plaintext

Type plaintext in Secret Text and generate ciphertext on the local device.

2. Send via Any Channel

Copy ciphertext and deliver it however you like — IM, email, or even a paper letter. The channel doesn't matter; only the ciphertext does.

3. Verify and Decrypt

Paste received ciphertext into Secret Text and decrypt after handshake and fingerprint checks.
