These keys come in pairs, a public and private key, so you can use somebody’s public key (which they can freely share. BITMESSAGE AND TOR: Bitmessage is a next-generation email protocol that is both fully decentralized and encrypted, allowing anyone to send messages to any. To anybody else the message will be scrambled and will seem like complete nonsense. Use a passphrase to make an address: If you use this option, you can recover your messages and keys as long as you remember the password. As BitMessage comes out of alpha we may see this change, but whether the developers want to get the protocol working well on mobile platforms remains to be seen. When you encrypt a message you are effectively locking it up so that only somebody with the correct key can unlock it. The current proof-of-work implementation is too computationally intensive for most SoC devices: I was able to get it working on an overclocked raspberry pi 2, but the processing delay between writing a message and upload made it unusable for instant messaging. While it is a solid communication proof of concept, BitMessage is barred from the mobile space. And as of version 0.3.5, the protocol supports “chans,” anonymous bbs-style mailing lists that are next to impossible to take down or censor they are a permanent part of the ledger, accessible to anyone who knows their address. It is decentralized and trustless, meaning that you need-not inherently trust any entities like root certificate authorities' and is a Encrypted Chat app in the file sharing category. There are more and more services popping up that connect it to traditional communications networks: bitmessage.ch and bitmail allow users to link a BitMessage alias to an email address, offering seamless end to end encryption out of the box. Bitmessage Alternatives Bitmessage is described as 'P2P communications protocol used to send encrypted messages to another person or to many subscribers. Bitmessage achieves anonymity and privacy by. Bitmessage is a communication protocol, not an all in one package. decentralized messaging system that enables users to exchange messages and prevents accidental eavesdropping. Its real utility, though, comes from its extensibility. The Raspberry Pi doesn’t have enough power to use BitMessage for IM Bitmessage offers to encrypt your communications without complex settings, key exchanges, or central servers.
