Instructions for Sending and Receiving Encrypted Data

The Center for Health Information Analysis is committed to protecting sensitive data. We have written this encryption program to ensure that data transmitted to us, or by us, is protected.

To electronically transmit sensitive data to us, you must use this program to encrypt it first.

CHIACryptor uses asymmetric encryption (i.e. public and private keys.)  The private key is 1024bit and the public key is 192bit.  The keys are generated using the RSA Cryptographic Services Provider.  The specific encryption algorithm used to encrypt files is not released.

Please uninstall any prior versions of CHIA Cryptor before downloading this software.

64 bit version of CHIA Cryptor,<Software> <User Manual> (Updated: Feb 2, 2010).

This version is compatible with Microsoft Windows XP and Vista running on a 64 bit computer only.

We have worked to simplify the installation process. If the software does not successfully install, please verify that you have proper permissions with your IT department before contacting us.

Once a file is encrypted, please use our FTP server to transmit it to us. <FTP Instructions>

CHIA has adopted encrypted file transmission via FTP to ensure privacy and avoid common problems associated with email attachments such as file size limitations and spam filtering. Please do not email sensitive data files to us as they will be rejected.
