Cyphr - Encrypted messaging simplified.
Cyphr makes encrypted messaging easy. All messages are encrypted, private and 100% yours. Generate your public and private key pair so only you can read your messages, start group conversations with friends, and share attachments privately.
ONLY YOU CAN READ YOUR MESSAGES. Cyphr generates a unique public and private key pair so only you and your friend can read your conversation - not us, not your phone company, and not a 3rd party. We take a zero-access approach, and give you total control of your data.
BE AS PRIVATE AS YOU WANT TO BE. Whether you are a casual user or a privacy fanatic, you can adjust Cyphr's settings to fit your privacy needs. If a feature requires information sharing, you can choose to disable that feature.
PRIVACY WITHOUT SACRIFICES. Cyphr doesn't sacrifice simplicity or features for privacy. Start single or group conversations, send attachments, and more.
WE DON'T STORE DATA ABOUT YOUR MESSAGES. We do not needlessly store information about you, your recipients or your messages.
MULTIPLE LAYERS OF SECURITY. Cyphr encrypts your messages using a combination of symmetric keys, and public and private key pairs. Cyphr also verifies messages with public key verification to ensure you and your friends know messages are from each other, not an impersonator. All messages are transmitted securely with SSL/TLS to protect your personal data, in addition to the message.
YOUR MESSAGES. OUR SERVERS. NO 3RD PARTIES. At Golden Frog we own our servers, write our code, and manage our own network to deliver the highest levels of security, speed and privacy. Cyphr servers are located in Switzerland for maximum user privacy and protection.
A COMPANY YOU CAN TRUST. Golden Frog's founders are Internet veterans who have fought to preserve online privacy, security and freedom since 1994.

Ratings and Reviews
Easy to use and very useful
There are a few programs out there encrypting text messages. The big difference with this one is that it allows you to set up one account use this on multiple devices - this might be considered a small security risk since one of the devices could get into the wrong hands and someone could impersonate the original account holder. Nevertheless, the user friendliness of having one account for all my devices is worth this risk with a self generated cypher key of 256 byte encryption. Cheers
Fuctional, no push notifications
Cyphr could be the perfect private messenger; however push notifications not working. I enabled at install (as per app support) and checked iOS settings. Hard and soft reset, no luck. Forums indicate that it's been a known issue for some time. Without this fundamental function it's hard to recommend Cypher.
Key-pair Generation Failing
Golden Frog, I would love to use this app but it keeps failing at key-pair generation.
I've browsed your FAQs and can't find anything relating to this issue. Is this something you guys are working on?
Since I love Golden Frog, ViprVPN, I'd absolutely give this 5 Stars once the issue is resolved. I know you guys respect privacy.
