Autocrypt
Autocrypt is a cryptographic protocol A security protocol (cryptographic protocol or encryption protocol) is an abstract or concrete protocol that performs a security-related function and applies cryptographic methods, often as sequences of cryptographic primitives. A protocol describe ... for email clients aiming to simplify key exchange and enabling encryption. Version 1.0 of thAutocrypt specificationwas released in December 2017 and makes no attempt to protect against MITM attacks. It is implemented on top of OpenPGP replacing its complex key management by fully automated unsecured exchange of Key (cryptography), cryptographic keys between peers . Method Autocrypt-capable email clients transparently negotiate encryption capabilities and preferences and exchange keys between users alongside sending regular emails. This is done by including the key material and encryption preferences in the header of each email, which allows encrypting any message to a contact who has prev ...

Enigmail
Enigmail is a data encryption and decryption extension for Mozilla Thunderbird and the Postbox that provides OpenPGP public key e-mail encryption and signing. Enigmail works under Microsoft Windows, Unix-like, and Mac OS X operating systems. Enigmail can operate with other mail clients compatible with PGP/MIME and inline PGP such as: Microsoft Outlook with Gpg4win package installed, Gnome Evolution, KMail, Claws Mail, Gnus, Mutt. Its cryptographic functionality is handled by GNU Privacy Guard. In their default configuration, Thunderbird and SeaMonkey provide e-mail encryption and signing using S/MIME, which relies on X.509 keys provided by a centralised certificate authority. Enigmail adds an alternative mechanism where cooperating users can instead use keys provided by a web of trust, which relies on multiple users to endorse the authenticity of the sender's and recipient's credentials. In principle this enhances security, since it does not rely on a centralised entity which migh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
