Abstract
Systems and methods for secure messaging are provided. A sender may encrypt content and send the encrypted content to a recipient over a communications network. The encrypted content may be decrypted for the recipient using a remote decryption service. Encrypted message content may be placed into a markup language form. Encrypted content may be incorporated into the form as a hidden form element. Form elements for collecting recipient credential information such as username and password information may also be incorporated into the form. At the recipient, the recipient may use the form to provide recipient credential information to the remote decryption service. The recipient may also use the form to upload the encrypted content from the form to the decryption service. The decryption service may provide the recipient with access to a decrypted version of the uploaded content over the communications network.
