Silent Circle - Security, Simplicity and Service

Silent Text Features:
Encrypted Instant Messaging
Secure File Transfer
Cross-Platform Functionality
Burn Notice

As a Silent Circle member using Silent Text, you can transmit encrypted text messages with attached files up to 100MB between Silent Circle members, anywhere, worldwide.

You decide how long your text can be seen by turning on the Burn feature. You can even manually delete sent messages, off both your device and the recipient’s device, simultaneously, with a touch of the bubble. Sent a sensitive document to the wrong person? Made a typo error or modified the contract? Simply redact what was sent with the touch of your screen.

Messages are encrypted on your device. New encryption keys are negotiated for each conversation. Every Silent Text message is encrypted to a new key that is only used once and then destroyed. There are no keys held anywhere after the conversation is complete.

Created by original innovators and globally recognized encryption experts using modern encryption algorithms: ECDH384 & AES256.

Silent Text uses Silent Circle Instant Messaging Protocol (SCIMP). Our founders are the creators of the world’s most widely used encryption software – PGP and ZRTP - open source, peer-reviewed encryption.

When a Silent Circle subscriber makes a phone call, sends a text, transfers a file or video chats with another Silent Circle member, that transmission is encrypted end-to-end from your own mobile device or computer on our proprietary Silent Network.

Members in over 130 countries. As seen in NY Times, Forbes, CNN, The Register, Business Insider, Slate, and many others around the world.
