8 | DESCRIPTION |
9 | ----------- | |
10 | ||
f1c236f8 | 11 | The OpenSSL Project is a collaborative effort to develop a robust, |
651d0aff | 12 | commercial-grade, fully featured, and Open Source toolkit implementing the |
26dee42d MC |
13 | Transport Layer Security (TLS) protocols (including SSLv3) as well as a |
14 | full-strength general purpose cryptographic library. | |
651d0aff | 15 | |
b06935f4 | 16 | OpenSSL is descended from the SSLeay library developed by Eric A. Young |
1c308226 | 17 | and Tim J. Hudson. The OpenSSL toolkit is licensed under a dual-license (the |
b06935f4 RS |
18 | OpenSSL license plus the SSLeay license), which means that you are free to |
19 | get and use it for commercial and non-commercial purposes as long as you | |
20 | fulfill the conditions of both licenses. | |

22 | OVERVIEW |
23 | -------- | |
24 | ||
1c308226 | 25 | The OpenSSL toolkit includes: |
651d0aff | 26 | |
f33d63c9 | 27 | libssl (with platform specific naming): |
b06935f4 | 28 | Provides the client and server-side implementations for SSLv3 and TLS. |
651d0aff | 29 | |
f33d63c9 | 30 | libcrypto (with platform specific naming): |
b06935f4 RS |
31 | Provides general cryptographic and X.509 support needed by SSL/TLS but |
32 | not logically part of it. | |
651d0aff | 33 | |
a2c96d88 | 34 | openssl: |
d7f0ab5f | 35 | A command line tool that can be used for: |
b06935f4 | 36 | Creation of key parameters |
a2c96d88 | 37 | Creation of X.509 certificates, CSRs and CRLs |
b06935f4 RS |
38 | Calculation of message digests |
39 | Encryption and decryption | |
40 | SSL/TLS client and server tests | |
d7f0ab5f | 41 | Handling of S/MIME signed or encrypted mail |
b06935f4 | 42 | And more... |

59 | If you have any problems with OpenSSL then please take the following steps |
60 | first: | |
61 | ||
7954dced | 62 | - Download the latest version from the repository |
d7f0ab5f | 63 | to see if the problem has already been addressed |
7954dced | 64 | - Configure with no-asm |
a2c96d88 | 65 | - Remove compiler optimisation flags |

67 | If you wish to report a bug then please include the following information |
68 | and create an issue on GitHub: | |
dfca822f | 69 | |
26dee42d MC |
70 | - OpenSSL version: output of 'openssl version -a' |
71 | - Any "Configure" options that you selected during compilation of the | |
72 | library if applicable (see INSTALL) | |
73 | - OS Name, Version, Hardware platform | |
74 | - Compiler Details (name, version) | |
d7f0ab5f UM |
75 | - Application Details (name, version) |
76 | - Problem Description (steps that will reproduce the problem, if known) | |
77 | - Stack Traceback (if the application dumps core) | |

932af161 | 79 | Just because something doesn't work the way you expect does not mean it |
26dee42d MC |
80 | is necessarily a bug in OpenSSL. Use the openssl-users email list for this type |
81 | of query. | |
