  • Form submissions without FormMailEncoder are insecure!

    A form submission from a customer travels across the World Wide Web to your server. It then travels to you via email.

    Throughout its journey, your customer's data is in clear text and is viewable by any eavesdropper!

    The HTTPS protocol only achieves partial security.

  • You need HTTPS and FormMailEncoder

    For full end-to-end security you need HTTPS between the user's browser and your server, then FormMailEncoder to encrypt the data from your server to your email inbox.

    The HTTPS protocol only achieves partial security.

    FormMailEncoder provides the security that HTTPS lacks - from your server to you.

  • How secure is FormMailEncoder/Decoder?

    FormMailEncoder uses the AES algorithm with a 128-bit key. The key is randomly generated for each message (i.e. each form submission) using truly random values supplied by your server's operating system. It protects this key using the RSA Public Key algorithm with a 2304-bit modulus.

    At current estimates, it would take a huge network of the fastest computers well over 50 years to guess a message key and decrypt the message.

  • Key management

    You can generate any number of RSA key pairs using FormMailDecoder. Each key pair is stored securely (using a password you choose) in a file on your local hard disk.

    You can copy a key file to other computers thereby allowing additional staff to decrypt messages with their copy of FormMailDecoder.

    In this way, several people in your organization can be authorized to view the encrypted messages from your forms.


FormMailEncoder is the software you install on your server. FormMailEncoder is free of charge and you can install it on any number of servers.

I am so glad I have found your FormMail script and FormMail Encoder/Decoder!

They are robust, have great features and are easy to install, configure and use. Very impressed with the care and competence with which you have addressed security and spam attack issues.

About Web Cryptography

Cryptography is the technology of protecting data so that only an authorized person can view it.

On the Web, the HTTPS protocol (URLs that begin with https:// and show a lock icon in your browser) is the most common form of cryptography and we all rely on it to protect our credit cards, bank accounts, and other private information.

Check out the short movie that shows how this works:

HTTPs Only Movie

The only problem is that HTTPS works from the user's browser to your server. After their private data reaches your server it is no longer protected.

This is where FormMailEncoder fills the gap!

FormMailEncoder provides the encryption from your server to your email inbox.

By utilizing HTTPS protocol to your server and FormMailEncoder from your server to you, you can provide end-to-end encryption for your customers and web site visitors.
