SSLeay 0.5.1 is now available. It should be quite stable and has documentation for the lower level cryptographic routines. It is incompatible with the previous version but has no global variables of consequence so it should be a much nicer starting point for threaded libraries. The library should have no memory leaks and the general cryptographic functionality has been filled out more. Tim Hudson <tjh@mincom.oz.au> will be updating the applications available on ftp.psy.uq.oz.au in the next few days. I leave for an 11 week holiday today so please address any problems and questions to the ssl-users@mincom.oz.au mailing list (if it is of general interest) or to ssleay@mincom.oz.au which goes to both myself and Tim Hudson (who will be fixing any bugs while I'm away). Anouncing software and then leaving for 3 months would probably not normally be considered a good practice but 0.5.0 has been tested for the last week or so and I have faith in Tim Hudson's ability to fix bugs after doing pre-alpha testing for the last 6 months :-) As per usual, the primary ftp site is ftp://ftp.psy.uq.oz.au/pub/Crypto/SSL http://www.psy.uq.oz.au/~ftp/Crypto Documentation on the demo application is sparse but I hope Tim Hudson will be able to fill in the gaps while I'm away :-) eric <eay@mincom.oz.au> -- SSLeay v 0.5.1 21/12/955 Copyright (c) 1995, Eric Young All rights reserved. This directory contains Eric Young's (eay@mincom.oz.au) 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.xx.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 written by Tim Hudson <tjh@mincom.oz.au> can be found at http://www.psy.uq.oz.au/~ftp/Crypto 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 :-). The package includes libssl.a: My implementation of Netscapes SSL v 2 protocol. This library implements the SSL protocol. libcrypto.a: General encryption and X509 stuff needed by SSL but not actual logically part of it. It include routines for the following: 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) a fast crypt(3), and routines to read passwords from the keyboard. RC4 encryption, IDEA encryption - 4 different modes, ecb, cbc, cfb and ofb. MD5 and MD2 message digest algorithms, SHA (SHA-0) and SHA-1 message digest algorithms, RSA encryption/decryption/key 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. X509 encoding/decoding into/from binary ASN1 and a PEM based ascii-binary encoding which supports encryption with a private key. 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. asn1parse - parse and display the structure of an asn1 encoded binary file. rsa - Manipulate RSA private keys. dh - Manipulate Diffie-Hellman parameter files. crl - Manipulate certificate revocation lists. 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. Documents included are A Postscript and html reference manual (written by Tim Hudson tjh@mincom.oz.au). A list of text protocol references I used. A initial version of the library manual. To install this package, read the INSTALL file. 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). 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@mincom.oz.au) 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-users-request@mincom.oz.au This library is reasonable stable now. Version 0.5 has had extensive rewriting since version 0.4. The purify package has been used extensively and I believe most if not all memory leaks have been removed. There are no writable global variable so a multi-threaded/DLL version of the library should be quite simple to write. Look at TODO for a list of thinks I know I still need to do. eric (December 1995) Eric Young (eay@mincom.oz.au) 86 Taunton St. Annerley 4103. Australia.
