  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. Secure Sockets Layer (SSLv3) and Transport Layer Security (TLS) protocols as
  10. well as a full-strength general purpose cryptograpic library. The project is
  11. managed by a worldwide community of volunteers that use the Internet to
  12. communicate, plan, and develop the OpenSSL toolkit and its related
  13. documentation.
  14. OpenSSL is descended from the SSLeay library developed by Eric A. Young
  15. and Tim J. Hudson. The OpenSSL toolkit is licensed under a dual-license (the
  16. OpenSSL license plus the SSLeay license), which means that you are free to
  17. get and use it for commercial and non-commercial purposes as long as you
  18. fulfill the conditions of both licenses.
  19. OVERVIEW
  20. --------
  21. The OpenSSL toolkit includes:
  22. libssl.a:
  23. Provides the client and server-side implementations for SSLv3 and TLS.
  24. libcrypto.a:
  25. Provides general cryptographic and X.509 support needed by SSL/TLS but
  26. not logically part of it.
  27. openssl:
  28. A command line tool that can be used for:
  29. Creation of key parameters
  30. Creation of X.509 certificates, CSRs and CRLs
  31. Calculation of message digests
  32. Encryption and decryption
  33. SSL/TLS client and server tests
  34. Handling of S/MIME signed or encrypted mail
  35. And more...
  36. INSTALLATION
  37. ------------
  38. See the appropriate file:
  39. INSTALL Linux, Unix, etc.
  40. INSTALL.DJGPP DOS platform with DJGPP
  41. INSTALL.NW Netware
  42. INSTALL.OS2 OS/2
  43. INSTALL.VMS VMS
  44. INSTALL.W32 Windows (32bit)
  45. INSTALL.W64 Windows (64bit)
  46. INSTALL.WCE Windows CE
  47. SUPPORT
  48. -------
  49. See the OpenSSL website www.openssl.org for details on how to obtain
  50. commercial technical support.
  51. If you have any problems with OpenSSL then please take the following steps
  52. first:
  53. - Download the latest version from the repository
  54. to see if the problem has already been addressed
  55. - Configure with no-asm
  56. - Remove compiler optimisation flags
  57. If you wish to report a bug then please include the following information
  58. and create an issue on GitHub:
  59. - On Unix systems:
  60. Self-test report generated by 'make report'
  61. - On other systems:
  62. OpenSSL version: output of 'openssl version -a'
  63. OS Name, Version, Hardware platform
  64. Compiler Details (name, version)
  65. - Application Details (name, version)
  66. - Problem Description (steps that will reproduce the problem, if known)
  67. - Stack Traceback (if the application dumps core)
  68. Just because something doesn't work the way you expect does not mean it
  69. is necessarily a bug in OpenSSL.
  70. HOW TO CONTRIBUTE TO OpenSSL

  73. LEGALITIES
  74. ----------
  75. A number of nations restrict the use or export of cryptography. If you
  76. are potentially subject to such restrictions you should seek competent
  77. professional legal advice before attempting to develop or distribute
  78. cryptographic code.
