  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.WIN Windows
  45. INSTALL.WCE Windows CE
  46. SUPPORT
  47. -------
  48. See the OpenSSL website www.openssl.org for details on how to obtain
  49. commercial technical support.
  50. If you have any problems with OpenSSL then please take the following steps
  51. first:
  52. - Download the current snapshot from ftp://ftp.openssl.org/snapshot/
  53. to see if the problem has already been addressed
  54. - Remove ASM versions of libraries
  55. - Remove compiler optimisation flags
  56. If you wish to report a bug then please include the following information in
  57. any bug report:
  58. - On Unix systems:
  59. Self-test report generated by 'make report'
  60. - On other systems:
  61. OpenSSL version: output of 'openssl version -a'
  62. OS Name, Version, Hardware platform
  63. Compiler Details (name, version)
  64. - Application Details (name, version)
  65. - Problem Description (steps that will reproduce the problem, if known)
  66. - Stack Traceback (if the application dumps core)
  67. Email the report to:
  68. rt@openssl.org
  69. In order to avoid spam, this is a moderated mailing list, and it might
  70. take a day for the ticket to show up. (We also scan posts to make sure
  71. that security disclosures aren't publically posted by mistake.) Mail
  72. to this address is recorded in the public RT (request tracker) database
  73. (see https://www.openssl.org/community/index.html#bugs for details) and
  74. also forwarded the public openssl-dev mailing list. Confidential mail
  75. may be sent to openssl-security@openssl.org (PGP key available from the
  76. key servers).
  77. Please do NOT use this for general assistance or support queries.
  78. Just because something doesn't work the way you expect does not mean it
  79. is necessarily a bug in OpenSSL.
  80. You can also make GitHub pull requests. If you do this, please also send
  81. mail to rt@openssl.org with a link to the PR so that we can more easily
  82. keep track of it.

  86. LEGALITIES
  87. ----------
  88. A number of nations, in particular the U.S., restrict the use or export
  89. of cryptography. If you are potentially subject to such restrictions
  90. you should seek competent professional legal advice before attempting to
  91. develop or distribute cryptographic code.
