By default, the ASE OLE DB Provider sends plain text passwords over the network to ASE for authentication. You can use this feature to change the default and encrypt passwords before they are sent over the network. When EncryptPassword is set to 1, the password is not sent over the wire until a login is negotiated; then, the password is encrypted and sent.
To encrypt passwords on Windows
Set the EncryptPassword property in the connection string to 1.
