SSLeay 0.9.1a 06-Jul-1998 Copyright (c) 1997, Eric Young All rights reserved. This directory contains Eric Young's (eay@cryptsoft.com) implementation of SSL and supporting libraries. The current version of this library is available from ftp://ftp.psy.uq.oz.au/pub/Crypto/SSL/SSLeay-x.x.x.tar.gz There are patches to a number of internet applications which can be found in ftp://ftp.psy.uq.oz.au/pub/Crypto/SSLapps/ A Web page containing the SSLeay FAQ written by Tim Hudson can be found at http://www.psy.uq.oz.au/~ftp/Crypto Additional documentation is being slowly written by Eric Young, and is being added to http://www.cryptsoft.com/ssleay/doc. It will normally also be available on http://www.psy.uq.oz.au/~ftp/Crypto/ssleay This Library and programs are FREE for commercial and non-commercial usage. The only restriction is that I must be attributed with the development of this code. See the COPYRIGHT file for more details. Donations would still be accepted :-). THIS LIBRARY IS NOT %100 COMPATABLE WITH SSLeay 0.6.6 The package includes libssl.a: My implementation of SSLv2, SSLv3 and the required code to support both SSLv2 and SSLv3 in the one server. libcrypto.a: General encryption and X509 stuff needed by SSL but not actually logically part of it. It includes routines for the following: Ciphers libdes - My libdes DES encryption package which has been floating around the net for a few years. 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 polular 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. X509v3 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. Programs in this package include enc - a general encryption program that can encrypt/decrypt using one of 17 different cipher/mode combinations. The input/output can also be converted to/from base64 ascii encoding. dgst - a generate message digesting program that will generate message digests for any of md2, md5, sha (sha-0 or sha-1) or mdc2. asn1parse - parse and display the structure of an asn1 encoded binary file. rsa - Manipulate RSA private keys. dsa - Manipulate DSA private keys. dh - Manipulate Diffie-Hellman parameter files. dsaparam- Manipulate and generate DSA parameter files. crl - Manipulate certificate revocation lists. crt2pkcs7- Generate a pkcs7 object containing a crl and a certificate. x509 - Manipulate x509 certificates, self-sign certificates. req - Manipulate PKCS#10 certificate requests and also generate certificate requests. genrsa - Generates an arbitrary sized RSA private key. gendh - Generates a set of Diffie-Hellman parameters, the prime will be a strong prime. ca - Create certificates from PKCS#10 certificate requests. This program also maintains a database of certificates issued. verify - Check x509 certificate signatures. speed - Benchmark SSLeay's ciphers. s_server- A test SSL server. s_client- A test SSL client. s_time - Benchmark SSL performance of SSL server programs. errstr - Convert from SSLeay hex error codes to a readable form. Documents avaliable are A Postscript and html reference manual (written by Tim Hudson tjh@cryptsoft.com). A list of text protocol references I used. An initial version of the library manual. To install this package, read the INSTALL file. For the Microsoft word, read MICROSOFT This library has been compiled and tested on Solaris 2.[34] (sparc and x86), SunOS 4.1.3, DGUX, OSF1 Alpha, HPUX 9, AIX 3.5(?), IRIX 5.[23], LINUX, NeXT (intel), linux, Windows NT, Windows 3.1, MSDOS 6.22. Multithreading has been tested under Windows NT and Solaris 2.5.1 Due to time constraints, the current release has only be rigorously tested on Solaris 2.[45], Linux and Windows NT. For people in the USA, it is possible to compile SSLeay to use RSA Inc.'s public key library, RSAref. From my understanding, it is claimed by RSA Inc. to be illegal to use my public key routines inside the USA. Read doc/rsaref.doc on how to build with RSAref. 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 used them. I will be working on documentation. Look at the example programs. There should be a SSL reference manual which is being put together by Tim Hudson (tjh@cryptsoft.com) in the same location as this distribution. This contains a lot more information that is very useful. For a description of X509 Certificates, their use, and certification, read rfc1421, rfc1422, rfc1423 and rfc1424. ssl/README also goes over the mechanism. We have setup some mailing lists for use by people that are interested in helping develop this code and/or ask questions. ssl-bugs@mincom.oz.au ssl-users@mincom.oz.au ssl-bugs-request@mincom.oz.au ssl-users-request@mincom.oz.au I have recently read about a new form of software, that which is in a permanent state of beta release. Linux and Netscape are 2 good examples of this, and I would also add SSLeay to this category. The Current stable release is 0.6.6. It has a few minor problems. 0.8.0 is not call compatable so make sure you have the correct version of SSLeay to link with. eric (Jun 1997) Eric Young (eay@cryptsoft.com) 86 Taunton St. Annerley 4103.
