Encrypted Emails PHP?

I have a form on one of my sites, when the form is submitted is there a way to encrypt the form? And then arrive in my email inbox un-encrypted?

Of would I have to encypt the form page? If so whats the easiest way to do wither of these things?

The form is a pretty standard PHP mailer type

Thanks

 

You can use the mcrypt http://php.net/mcrypt function to encrypt a string, and then email it and decrypt it locally using the same key.

If you need really strong encryption, here is a relly good AES class that will allow up to 256 Bit AES encryption.

I would encrypt, base64_encode, and then email it. You would then need to base64_decode, and decrypt it locally. You could also use a dynamic key like the specific email address with a salt.

 

i think mcrypt might do it, but do you have to decrypt manually?

 

When the email is received, it will be encrypted. At some point it will need to be decrypted so that it can be read. I don't now of any built-in function for an email program to decrypt a message.

 

hmm, is there a more secure way to send emails? https?
