  1. This file is part of the OpenSSH software.
  2. The licences which components of this software fall under are as
  3. follows. First, we will summarize and say that all components
  4. are under a BSD licence, or a licence more free than that.
  5. OpenSSH contains no GPL code.
  6. 1)
  7. * Copyright (c) 1995 Tatu Ylonen <ylo@cs.hut.fi>, Espoo, Finland
  8. * All rights reserved
  9. *
  10. * As far as I am concerned, the code I have written for this software
  11. * can be used freely for any purpose. Any derived versions of this
  12. * software must be clearly marked as such, and if the derived work is
  13. * incompatible with the protocol description in the RFC file, it must be
  14. * called by a name other than "ssh" or "Secure Shell".
  15. [Tatu continues]
  16. * However, I am not implying to give any licenses to any patents or
  17. * copyrights held by third parties, and the software includes parts that
  18. * are not under my direct control. As far as I know, all included
  19. * source code is used in accordance with the relevant license agreements
  20. * and can be used freely for any purpose (the GNU license being the most
  21. * restrictive); see below for details.
  22. [However, none of that term is relevant at this point in time. All of
  23. these restrictively licenced software components which he talks about
  24. have been removed from OpenSSH, i.e.,
  25. - RSA is no longer included, found in the OpenSSL library
  26. - IDEA is no longer included, its use is deprecated
  27. - DES is now external, in the OpenSSL library
  28. - GMP is no longer used, and instead we call BN code from OpenSSL
  29. - Zlib is now external, in a library
  30. - The make-ssh-known-hosts script is no longer included
  31. - TSS has been removed
  32. - MD5 is now external, in the OpenSSL library
  33. - RC4 support has been replaced with ARC4 support from OpenSSL
  34. - Blowfish is now external, in the OpenSSL library
  35. [The licence continues]
  36. Note that any information and cryptographic algorithms used in this
  37. software are publicly available on the Internet and at any major
  38. bookstore, scientific library, and patent office worldwide. More
  39. information can be found e.g. at "http://www.cs.hut.fi/crypto".
  40. The legal status of this program is some combination of all these
  41. permissions and restrictions. Use only at your own responsibility.
  42. You will be responsible for any legal consequences yourself; I am not
  43. making any claims whether possessing or using this is legal or not in
  44. your country, and I am not taking any responsibility on your behalf.
  45. NO WARRANTY
  46. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
  47. FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
  48. OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
  49. PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
  50. OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
  51. MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
  52. TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
  53. PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
  54. REPAIR OR CORRECTION.
  55. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
  56. WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
  57. REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
  58. INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
  59. OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
  60. TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
  61. YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
  62. PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
  63. POSSIBILITY OF SUCH DAMAGES.
