How It Works

How CryptnSend works

  • Continue to use your existing email account as before. It really doesn't matter whether it is a free email account like Gmail, Yahoo, MSN or email account with your own domain name extension.
  • Subscribe to CryptnSend service for your existing email address.
  • Start sending secure, HIPAA compliant email messages using the same email address. Messages can be composed and sent in four different ways:

  • Message is delivered to MDVault once message is sent. MDVault encrypts the message and holds it in secure server without delivering to the recipient. A notification is sent to the recipient informing that a secure, encrypted email message has been received.
  • By clicking the secure web-link in the notification the recipient can log into MDVault Secure Server to decrypt, view the message and download attachments if any.

Other important features of CryptnSend include:

MDofficeMail works with almost all the systems:
  • Legal Archival. All the messages sent using CryptnSend are stored in a secure, remote server as soon as they are sent. These messages can not be edited or deleted. However they can be viewed and downloaded.
  • New recipient validation: By selecting this option while composing a message sender can restrict a new recipient from viewing the message without a security token. This token can be conveyed to the recipient over phone.
  • Password reset authorization: Unless the sender authorizes, recipient cannot reset a forgotten password to view a secure message.
  • Validation of recipient to reset password: Optionally, the sender can validate the recipient requesting for a reset of a forgotten password.
  • Option to send encrypted or plain message.
  • Download and Store locally: Recipient can save decrypted message to any local folder or email client folder.
  • Access logs: Access logs can be viewed for each user, as required by HIPAA

Are there any limitations with CryptnSend?

MDVault uses industry-standard AES-256 encryption in CBC mode with MD5 hash. Many federal agencies and financial institutions around the globe use the same class of encryption to protect very sensitive data. AES-256 encryption is so secure that there are no publicly-known attacks that will recover anything useful from an AES-256 encrypted file in any remotely reasonable amount of time.
