Button Encryption

If you choose Button Encryption in the Button Factory, which is the default value, your 

website payments will be secure, thus both you and your customers remain protected. PayPal 

automatically encrypts your confidential information using the Secure Sockets Layer (SSL) 

protocol with an encryption key length of 128 bits (the highest level commercially available).

:

PayPal highly recommends encrypting your button code; however, doing so has three 

limitations:

1. Encrypted button HTML is not editable. If you want tp modify your button code manually, 

select No for this option.

2. You will not be able to encrypt your button if it has dynamically generated code from the 

Add More Options page, such as drop down Options fields (see step 5). If you need 

Option fields for your products, select No to turn encryption off.

3. If you choose to encrypt your button, you will not be able to create an email link.
