     In case this group has not heard, RSA Data Security has
clarified that there is no charge for using the DESX algorithm,
which is described in draft-simpson-desx-02.txt.

Subject: Legal claims on encryption and authentication algorithm



Hello,
     While reading RFC 1321, I noted that if we use MD5, we must state that
it was developped by RSA Data Security, Inc.
     We use other encryption and authentication algorithms. Is there any
legal claims (copyrights, patents, etc.) tied to the following algorithms?
- Blowfish
- DES
- 3DES
- SHA-1
     Thank you
