Two Major Options• Encryption

– Pretty Good Privacy (PGP)– VeriCrypt, FileCrypt, Gnu Privacy Guard

• Secure file transfer– SSH2 protocol (includes SCP, SFTP,

FTPS, and Active FTPS)

• Either option is available for UNIX, Mac, or Windows

Steps to Using PGPwith the SPEEDE Server

• Obtain and install a copy of the PGP software • Use PGP to generate a public and private key

pair• Exchange public keys with the Server• Encrypt your outgoing files with the Server’s

public key• When you receive an encrypted file, decrypt it

with your private key before processing

• You must use RSA keys

Our Sincere Apologies

On Tuesday, April 10, we upgraded our sending SPEEDE server. Soon, we discovered that not everyone could decrypt what we were sending from this new server. So on Wednesday, April 18, we switched back to the previous sending server (and resent all data to those schools experiencing the problem).

We are currently testing to solve the problem.

• Obtain and install SSH2 software suite• Email your IP address, along with a userID and

password, to the server (regist@ediserver.reg.utexas.edu)

• Server will set up public key authentication on your sftp server, for sending via sftp* to you

*this includes scp and pure sftp – ftps (passive) andactive ftps both use userid and password

Steps to Using SSHwith the SPEEDE Server

** Sending **

• Notify the server that you wish to send via sftp (regist@ediserver.reg.utexas.edu)

• You may upload a public key to the Server to avoid having to use password

• Otherwise, you will use a userID and password when sending files
