  5. DESCRIPTION
  6. -----------
  7. The OpenSSL Project is a collaborative effort to develop a robust,
  8. commercial-grade, fully featured, and Open Source toolkit implementing the
  9. Transport Layer Security (TLS) protocols (including SSLv3) as well as a
  10. full-strength general purpose cryptographic library.
  11. OpenSSL is descended from the SSLeay library developed by Eric A. Young
  12. and Tim J. Hudson. The OpenSSL toolkit is licensed under a dual-license (the
  13. OpenSSL license plus the SSLeay license), which means that you are free to
  14. get and use it for commercial and non-commercial purposes as long as you
  15. fulfill the conditions of both licenses.
  16. OVERVIEW
  17. --------
  18. The OpenSSL toolkit includes:
  19. libssl (with platform specific naming):
  20. Provides the client and server-side implementations for SSLv3 and TLS.
  21. libcrypto (with platform specific naming):
  22. Provides general cryptographic and X.509 support needed by SSL/TLS but
  23. not logically part of it.
  24. openssl:
  25. A command line tool that can be used for:
  26. Creation of key parameters
  27. Creation of X.509 certificates, CSRs and CRLs
  28. Calculation of message digests
  29. Encryption and decryption
  30. SSL/TLS client and server tests
  31. Handling of S/MIME signed or encrypted mail
  32. And more...
  33. INSTALLATION
  34. ------------
  35. See the appropriate file:
  36. INSTALL Linux, Unix, Windows, OpenVMS, ...
  37. NOTES.* INSTALL addendums for different platforms
  38. SUPPORT
  39. -------
  40. See the OpenSSL website www.openssl.org for details on how to obtain
  41. commercial technical support. Free community support is available through the
  42. openssl-users email list (see
  43. https://www.openssl.org/community/mailinglists.html for further details).
  44. If you have any problems with OpenSSL then please take the following steps
  45. first:
  46. - Download the latest version from the repository
  47. to see if the problem has already been addressed
  48. - Configure with no-asm
  49. - Remove compiler optimization flags
  50. If you wish to report a bug then please include the following information
  51. and create an issue on GitHub:
  52. - OpenSSL version: output of 'openssl version -a'
  53. - Configuration data: output of 'perl configdata.pm --dump'
  54. - OS Name, Version, Hardware platform
  55. - Compiler Details (name, version)
  56. - Application Details (name, version)
  57. - Problem Description (steps that will reproduce the problem, if known)
  58. - Stack Traceback (if the application dumps core)
  59. Just because something doesn't work the way you expect does not mean it
  60. is necessarily a bug in OpenSSL. Use the openssl-users email list for this type
  61. of query.

  65. LEGALITIES
  66. ----------
  67. A number of nations restrict the use or export of cryptography. If you
  68. are potentially subject to such restrictions you should seek competent
  69. professional legal advice before attempting to develop or distribute
  70. cryptographic code.
