Title: WP jCryption Security Author: andreyk Published: Gener 1, 2015 Last modified: Maig 16, 2015 --- Search plugins ![](https://ps.w.org/wp-jcryption/assets/banner-772x250.png?rev=1057868) This plugin **hasn’t been tested with the latest 3 major releases of WordPress**. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress. ![](https://s.w.org/plugins/geopattern-icon/wp-jcryption_68bca9.svg) # WP jCryption Security By [andreyk](https://profiles.wordpress.org/andreyk/) [Download](https://downloads.wordpress.org/plugin/wp-jcryption.zip) * [Details](https://bal.wordpress.org/plugins/wp-jcryption/#description) * [Reviews](https://bal.wordpress.org/plugins/wp-jcryption/#reviews) * [Installation](https://bal.wordpress.org/plugins/wp-jcryption/#installation) * [Development](https://bal.wordpress.org/plugins/wp-jcryption/#developers) [Support](https://wordpress.org/support/plugin/wp-jcryption/) ## Description The plugin increases security of a site in case it has no SSL certificate, useful for owners of small sites who want to secure their passwords and other posted data but don’t want to buy SSL certificate for each domain and subdomain: it protects from sniffering the most important data such as passwords when they are being sent from forms of your site to the server. When the form served by the plugin is submitted all input data are being joined into a string, then this string is being encrypted with AES algorythm by disposable key and only encrypred string will be sent. A browser encrypts the disposable key in javascript by the RSA public key and sends it to the server; then the server decrypts it with the RSA private key and then use it to decrypt the posted data with AES. Translations included: Ukrainian, Russian, German and Brazilian Portuguese. I just adapted usage in WordPress the jCryption jQuery plugin, v. 3.1.0. Please check www.jcryption.org to learn how jCryption works. ## Screenshots * [[ * HTTP headers without encryption. * [[ * Log-in process encrypted by WP jCryption. ## Installation Upload wp-jcryption.zip using the wordpress plugin installation interface and activate the plugin. On the very first activation 1024-bit RSA key pair will be generated and the list of forms the plugin is primarily destinated for will be saved. You may add other form IDs to this list on the plugin settings page: Settings – WP jCryption. ## FAQ Installation Instructions Upload wp-jcryption.zip using the wordpress plugin installation interface and activate the plugin. On the very first activation 1024-bit RSA key pair will be generated and the list of forms the plugin is primarily destinated for will be saved. You may add other form IDs to this list on the plugin settings page: Settings – WP jCryption. Why should I use this plugin? If you don’t use https on your site your password could be stolen through man-in- the-middle attack when you are submitting log-in form because form data (including password) are being sent as plain text. This plugin encrypts submitted data in a way similar to https transmission. Does this plugin encrypts transmission of my site pages entirely? No. The plugin encrypts only data being posted from most important forms (that contain password fields: login, reset password, user profile) and forms you specify additionally. To secure all incoming and outgoing traffic of your site a SSL certificate is needed. I have SSL certificate installed on my site already. Do I need to install the plugin? No. Can I check whether the form data are being sent encrypted? Yes, you can do it by means of Firefox LiveHTTPHeaders extension, Fiddler or similar tools. What are system requirements for the plugin? PHP version >= 5.3 with OpenSSL PHP extension. Do I need to generate RSA private and public key files with Linux commands? No. PHP generates keys for you and save them in a database. So, this plugin is usable on (almost) any shared hosting. The plugin works with login form but disables other form during it’s being submitted. Try to enable the plugin option: Fix button id=”submit” and name=”submit”. ## Reviews ![](https://secure.gravatar.com/avatar/b6853eab0d51da161561de8cca10ba04b2cea39ed97c1f728acea8fcc5ffe617? s=60&d=retro&r=g) ### 󠀁[Don't have SSL? Then this is indispensable!](https://wordpress.org/support/topic/dont-have-ssl-then-this-is-indispensable/)󠁿 [Gahapati](https://profiles.wordpress.org/gahapati/) Setembre 3, 2016 For a number of years I found this plugin to be quite indispensable, since until recently I did not have access to SSL-encryption. If ever I were to set up WordPress on a server that lacked SSL again, WP jCryption Security would be the first plugin to install! ![](https://secure.gravatar.com/avatar/93a1c7798169c84b5cabf316a321e86190361e5b82a8ae0f19770f0546fcde42? s=60&d=retro&r=g) ### 󠀁[Great](https://wordpress.org/support/topic/great-4369/)󠁿 [sotnas](https://profiles.wordpress.org/sotnas/) Setembre 3, 2016 A small necessary tool!
