| 41 DESCRIPTION |
| 42 ----------- |
| 43 |
| 44 The OpenSSL Project is a collaborative effort to develop a robust, |
| 45 commercial-grade, fully featured, and Open Source toolkit implementing the |
| 46 Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) |
| 47 protocols as well as a full-strength general purpose cryptography library. |
| 48 The project is managed by a worldwide community of volunteers that use the |
| 49 Internet to communicate, plan, and develop the OpenSSL toolkit and its |
| 50 related documentation. |
| 51 |
| 52 OpenSSL is based on the excellent SSLeay library developed from Eric A. Young |
| 53 and Tim J. Hudson. The OpenSSL toolkit is licensed under a dual-license (the |
| 54 OpenSSL license plus the SSLeay license) situation, which basically means |
| 55 that you are free to get and use it for commercial and non-commercial |
| 56 purposes as long as you fulfill the conditions of both licenses. |
| 57 |
| 58 OVERVIEW |
| 59 -------- |
| 60 |
| 61 The OpenSSL toolkit includes: |
| 62 |
| 63 libssl.a: |
| 64 Implementation of SSLv2, SSLv3, TLSv1 and the required code to support |
| 65 both SSLv2, SSLv3 and TLSv1 in the one server and client. |
| 66 |
| 67 libcrypto.a: |
| 68 General encryption and X.509 v1/v3 stuff needed by SSL/TLS but not |
| 69 actually logically part of it. It includes routines for the following: |
| 70 |
| 71 Ciphers |
| 72 libdes - EAY's libdes DES encryption package which was floating |
| 73 around the net for a few years, and was then relicensed by |
| 74 him as part of SSLeay. It includes 15 'modes/variations' |
| 75 of DES (1, 2 and 3 key versions of ecb, cbc, cfb and ofb; |
| 76 pcbc and a more general form of cfb and ofb) including desx |
| 77 in cbc mode, a fast crypt(3), and routines to read |
| 78 passwords from the keyboard. |
| 79 RC4 encryption, |
| 80 RC2 encryption - 4 different modes, ecb, cbc, cfb and ofb. |
| 81 Blowfish encryption - 4 different modes, ecb, cbc, cfb and ofb. |
| 82 IDEA encryption - 4 different modes, ecb, cbc, cfb and ofb. |
| 83 |
| 84 Digests |
| 85 MD5 and MD2 message digest algorithms, fast implementations, |
| 86 SHA (SHA-0) and SHA-1 message digest algorithms, |
| 87 MDC2 message digest. A DES based hash that is popular on smart cards. |
| 88 |
| 89 Public Key |
| 90 RSA encryption/decryption/generation. |
| 91 There is no limit on the number of bits. |
| 92 DSA encryption/decryption/generation. |
| 93 There is no limit on the number of bits. |
| 94 Diffie-Hellman key-exchange/key generation. |
| 95 There is no limit on the number of bits. |
| 96 |
| 97 X.509v3 certificates |
| 98 X509 encoding/decoding into/from binary ASN1 and a PEM |
| 99 based ASCII-binary encoding which supports encryption with a |
| 100 private key. Program to generate RSA and DSA certificate |
| 101 requests and to generate RSA and DSA certificates. |
| 102 |
| 103 Systems |
| 104 The normal digital envelope routines and base64 encoding. Higher |
| 105 level access to ciphers and digests by name. New ciphers can be |
| 106 loaded at run time. The BIO io system which is a simple non-blocking |
| 107 IO abstraction. Current methods supported are file descriptors, |
| 108 sockets, socket accept, socket connect, memory buffer, buffering, SSL |
| 109 client/server, file pointer, encryption, digest, non-blocking testing |
| 110 and null. |
| 111 |
| 112 Data structures |
| 113 A dynamically growing hashing system |
| 114 A simple stack. |
| 115 A Configuration loader that uses a format similar to MS .ini files. |
| 116 |
| 117 openssl: |
| 118 A command line tool that can be used for: |
| 119 Creation of RSA, DH and DSA key parameters |
| 120 Creation of X.509 certificates, CSRs and CRLs |
| 121 Calculation of Message Digests |
| 122 Encryption and Decryption with Ciphers |
| 123 SSL/TLS Client and Server Tests |
| 124 Handling of S/MIME signed or encrypted mail |
| 125 |
| 126 |
| 127 PATENTS |
| 128 ------- |
| 129 |
| 130 Various companies hold various patents for various algorithms in various |
| 131 locations around the world. _YOU_ are responsible for ensuring that your use |
| 132 of any algorithms is legal by checking if there are any patents in your |
| 133 country. The file contains some of the patents that we know about or are |
| 134 rumored to exist. This is not a definitive list. |
| 135 |
| 136 RSA Security holds software patents on the RC5 algorithm. If you |
| 137 intend to use this cipher, you must contact RSA Security for |
| 138 licensing conditions. Their web page is http://www.rsasecurity.com/. |
| 139 |
| 140 RC4 is a trademark of RSA Security, so use of this label should perhaps |
| 141 only be used with RSA Security's permission. |
| 142 |
| 143 The IDEA algorithm is patented by Ascom in Austria, France, Germany, Italy, |
| 144 Japan, the Netherlands, Spain, Sweden, Switzerland, UK and the USA. They |
| 145 should be contacted if that algorithm is to be used; their web page is |
| 146 http://www.ascom.ch/. |
| 147 |
| 148 NTT and Mitsubishi have patents and pending patents on the Camellia |
| 149 algorithm, but allow use at no charge without requiring an explicit |
| 150 licensing agreement: http://info.isl.ntt.co.jp/crypt/eng/info/chiteki.html |
| 151 |
| 152 INSTALLATION |
| 153 ------------ |
| 154 |
| 155 To install this package under a Unix derivative, read the INSTALL file. For |
| 156 a Win32 platform, read the INSTALL.W32 file. For OpenVMS systems, read |
| 157 INSTALL.VMS. |
| 158 |
| 159 Read the documentation in the doc/ directory. It is quite rough, but it |
| 160 lists the functions; you will probably have to look at the code to work out |
| 161 how to use them. Look at the example programs. |
| 162 |
| 163 PROBLEMS |
| 164 -------- |
| 165 |
| 166 For some platforms, there are some known problems that may affect the user |
| 167 or application author. We try to collect those in doc/PROBLEMS, with current |
| 168 thoughts on how they should be solved in a future of OpenSSL. |
| 169 |
| 170 SUPPORT |
| 171 ------- |
| 172 |
| 173 See the OpenSSL website www.openssl.org for details of how to obtain |
| 174 commercial technical support. |
| 175 |
| 176 If you have any problems with OpenSSL then please take the following steps |
| 177 first: |
| 178 |
| 179 - Download the current snapshot from ftp://ftp.openssl.org/snapshot/ |
| 180 to see if the problem has already been addressed |
| 181 - Remove ASM versions of libraries |
| 182 - Remove compiler optimisation flags |
| 183 |
| 184 If you wish to report a bug then please include the following information in |
| 185 any bug report: |
| 186 |
| 187 - On Unix systems: |
| 188 Self-test report generated by 'make report' |
| 189 - On other systems: |
| 190 OpenSSL version: output of 'openssl version -a' |
| 191 OS Name, Version, Hardware platform |
| 192 Compiler Details (name, version) |
| 193 - Application Details (name, version) |
| 194 - Problem Description (steps that will reproduce the problem, if known) |
| 195 - Stack Traceback (if the application dumps core) |
| 196 |
| 197 Report the bug to the OpenSSL project via the Request Tracker |
| 198 (http://www.openssl.org/support/rt.html) by mail to: |
| 199 |
| 200 openssl-bugs@openssl.org |
| 201 |
| 202 Note that the request tracker should NOT be used for general assistance |
| 203 or support queries. Just because something doesn't work the way you expect |
| 204 does not mean it is necessarily a bug in OpenSSL. |
| 205 |
| 206 Note that mail to openssl-bugs@openssl.org is recorded in the publicly |
| 207 readable request tracker database and is forwarded to a public |
| 208 mailing list. Confidential mail may be sent to openssl-security@openssl.org |
| 209 (PGP key available from the key servers). |
| 210 |
| 211 HOW TO CONTRIBUTE TO OpenSSL |
| 212 ---------------------------- |
| 213 |
| 214 Development is coordinated on the openssl-dev mailing list (see |
| 215 http://www.openssl.org for information on subscribing). If you |
| 216 would like to submit a patch, send it to openssl-bugs@openssl.org with |
| 217 the string "[PATCH]" in the subject. Please be sure to include a |
| 218 textual explanation of what your patch does. |
| 219 |
| 220 If you are unsure as to whether a feature will be useful for the general |
| 221 OpenSSL community please discuss it on the openssl-dev mailing list first. |
| 222 Someone may be already working on the same thing or there may be a good |
| 223 reason as to why that feature isn't implemented. |
| 224 |
| 225 Patches should be as up to date as possible, preferably relative to the |
| 226 current CVS or the last snapshot. They should follow the coding style of |
| 227 OpenSSL and compile without warnings. Some of the core team developer targets |
| 228 can be used for testing purposes, (debug-steve64, debug-geoff etc). OpenSSL |
| 229 compiles on many varied platforms: try to ensure you only use portable |
| 230 features. |
| 231 |
| 232 Note: For legal reasons, contributions from the US can be accepted only |
| 233 if a TSU notification and a copy of the patch are sent to crypt@bis.doc.gov |
| 234 (formerly BXA) with a copy to the ENC Encryption Request Coordinator; |
| 235 please take some time to look at |
| 236 http://www.bis.doc.gov/Encryption/PubAvailEncSourceCodeNofify.html [sic] |
| 237 and |
| 238 http://w3.access.gpo.gov/bis/ear/pdf/740.pdf (EAR Section 740.13(e)) |
| 239 for the details. If "your encryption source code is too large to serve as |
| 240 an email attachment", they are glad to receive it by fax instead; hope you |
| 241 have a cheap long-distance plan. |
| 242 |
| 243 Our preferred format for changes is "diff -u" output. You might |
| 244 generate it like this: |
| 245 |
| 246 # cd openssl-work |
| 247 # [your changes] |
| 248 # ./Configure dist; make clean |
| 249 # cd .. |
| 250 # diff -ur openssl-orig openssl-work > mydiffs.patch |
