The OpenSSL Project is a collaborative effort to develop a robust,
commercial-grade, fully featured, and Open Source toolkit implementing the
- Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1)
- protocols as well as a full-strength general purpose cryptography library.
- The project is managed by a worldwide community of volunteers that use the
- Internet to communicate, plan, and develop the OpenSSL toolkit and its
- related documentation.

The OpenSSL toolkit includes:
libssl.a:
- Implementation of SSLv2, SSLv3, TLSv1 and the required code to support
- both SSLv2, SSLv3 and TLSv1 in the one server and client.
+ Provides the client and server-side implementations for SSLv3 and TLS.
libcrypto.a:
- General encryption and X.509 v1/v3 stuff needed by SSL/TLS but not
- actually logically part of it. It includes routines for the following:
-
- Ciphers
- libdes - EAY's libdes DES encryption package which was floating
- around the net for a few years, and was then relicensed by
- him as part of SSLeay. It includes 15 'modes/variations'
- of DES (1, 2 and 3 key versions of ecb, cbc, cfb and ofb;
- pcbc and a more general form of cfb and ofb) including desx
- in cbc mode, a fast crypt(3), and routines to read
- passwords from the keyboard.
- RC4 encryption,
- RC2 encryption - 4 different modes, ecb, cbc, cfb and ofb.
- Blowfish encryption - 4 different modes, ecb, cbc, cfb and ofb.
- IDEA encryption - 4 different modes, ecb, cbc, cfb and ofb.
-
- Digests
- MD5 and MD2 message digest algorithms, fast implementations,
- SHA (SHA-0) and SHA-1 message digest algorithms,
- MDC2 message digest. A DES based hash that is popular on smart cards.
-
- Public Key
- RSA encryption/decryption/generation.
- There is no limit on the number of bits.
- DSA encryption/decryption/generation.
- There is no limit on the number of bits.
- Diffie-Hellman key-exchange/key generation.
- There is no limit on the number of bits.
-
- X.509v3 certificates
- X509 encoding/decoding into/from binary ASN1 and a PEM
- based ASCII-binary encoding which supports encryption with a
- private key. Program to generate RSA and DSA certificate
- requests and to generate RSA and DSA certificates.
-
- Systems
- The normal digital envelope routines and base64 encoding. Higher
- level access to ciphers and digests by name. New ciphers can be
- loaded at run time. The BIO io system which is a simple non-blocking
- IO abstraction. Current methods supported are file descriptors,
- sockets, socket accept, socket connect, memory buffer, buffering, SSL
- client/server, file pointer, encryption, digest, non-blocking testing
- and null.
-
- Data structures
- A dynamically growing hashing system
- A simple stack.
- A Configuration loader that uses a format similar to MS .ini files.
+ Provides general cryptographic and X.509 support needed by SSL/TLS but
+ not logically part of it.
openssl:
A command line tool that can be used for:
- Creation of RSA, DH and DSA key parameters
+ Creation of key parameters
Creation of X.509 certificates, CSRs and CRLs
- Calculation of Message Digests
- Encryption and Decryption with Ciphers
- SSL/TLS Client and Server Tests
+ Calculation of message digests
+ Encryption and decryption
+ SSL/TLS client and server tests
Handling of S/MIME signed or encrypted mail
+ And more...
INSTALLATION
------------
- To install this package under a Unix derivative, read the INSTALL file. For
- a Win32 platform, read the INSTALL.W32 file. For OpenVMS systems, read
- INSTALL.VMS.
-
- Read the documentation in the doc/ directory. It is quite rough, but it
- lists the functions; you will probably have to look at the code to work out
- how to use them. Look at the example programs.
-
- PROBLEMS
- --------
-
- For some platforms, there are some known problems that may affect the user
- or application author. We try to collect those in doc/PROBLEMS, with current
- thoughts on how they should be solved in a future of OpenSSL.
+ See the appropriate file:
+ INSTALL Linux, Unix, etc.
+ INSTALL.DJGPP DOS platform with DJGPP
+ INSTALL.NW Netware
+ INSTALL.OS2 OS/2
+ INSTALL.VMS VMS
+ INSTALL.W32 Windows (32bit)
+ INSTALL.W64 Windows (64bit)
+ INSTALL.WCE Windows CE
