How does it work ?

wp2pgpmail includes an OpenPGP Message Encryption System in Javascript, based on Herbert Hanewinkel’s work. Visitors enter a message in a form, encrypt it (with the PGP public key you entered in wp2pgpmail option settings), then an e-mail is sent to you (blog admin e-mail address). The message is encrypted locally on the visitor’s computer, so no data is transfered in clear !

Is it secure ?

All code is implememented in readable Javascript.
You can verify the source code.
No binaries are loaded from a server or used embedded.
No hidden transfer of plain text.

Supported languages :

English
French
German
Spanish
Estonian
Greek
Indonesian

FAQ
