- Enigma Plugin for Roundcube
- This plugin adds support for viewing and sending of signed and encrypted
- messages in PGP (RFC 2440) and PGP/MIME (RFC 3156) format.
- The plugin uses gpg binary on the server and stores all keys
- (including private keys of the users) on the server.
- Encryption/decryption is done server-side. So, this plugin
- is for users that trust the server.
- Implemented features:
- ---------------------
- + PGP: signatures verification
- + PGP: messages decryption
- + PGP: Sending of encrypted/signed messages
- + PGP: keys management UI (key import, export, delete)
- + PGP: key generation (client- or server-side)
- + Handling of PGP keys attached to incoming messages
- + User preferences to disable plugin features
- + Attaching public keys to email
- + Key server(s) support (search, import)
- TODO:
- -----
- - Handling of big messages with temp files (? - security)
- - Key info in contact details page (optional)
- - Extended key management:
- - disable,
- - revoke,
- - change expiration date, change passphrase, add photo,
- - manage user IDs
- - export private keys
- - Generate revocation certs
- - Search filter to see invalid/expired keys
- - Key server(s) support (upload, refresh)
- - Mark keys as trusted/untrasted, display appropriate message in verify/decrypt status
- - Support for multi-server installations (store keys in sql database? probably impossible with GnuPG 2.1)
- - Performance improvements:
- - cache decrypted message key id so we can skip decryption if we have no password in session
- - cache (last or successful only?) sig verification status to not verify on every msg preview (optional)
- - S/MIME: Certs generation (?)
- - S/MIME: Certs management
- - S/MIME: signed messages verification
- - S/MIME: encrypted messages decryption
- - S/MIME: Sending signed/encrypted messages
- - S/MIME: Handling of certs attached to incoming messages
- - S/MIME: Certificate info in Contacts details page (optional)
- KNOWN ISSUES:
- -------------
- There are some known issues with accepting key passphrases on various
- system configurations. This is caused by issues in PinEntry handling.
- Make sure that vendor/bin/crypt-gpg-pinentry works from command line.
- Possible reasons:
- - non-working loader in shebang (#! /usr/bin/env php)
- Make sure it works for the user the php scripts are executed upon
- (i.e. apache, www-date, etc.)
- Note: pinentry is used with gpg >= 2.0 and <= 2.1.12.
- Note: for server use GnuPG developers still recommend version 1.4.
