Subject: VOUCH program encrypts with DSS keys
Message-ID: <01H9AE8TXK1094G4CB@delphi.com>
MIME-Version: 1.0

There is a program called VOUCH which implements the Digital Signature
Standard. In addition to signing, it has the interesting ability to do
public-key encryption with the DSS keys! The manual describes this as
Diffie-Hellman key exchange. As I understand DH exchange, it is an online
negotiation protocol. Can DH be combined with DSS to use the DSS keys
for public-key encryption? How? If His Excellency decides we should all
have DSS keys tattooed on our asses, the ability to encrypt with them
could be very useful.
Vouch is available by ftp from garbo.uwasa.fi in /pc/crypt/vouch10.zip
It's about 90K. The author is in Pakistan and gives only a snail address.
