Use the new pipeline cipher capability to encrypt multiple records being written out all in one go. Two new SSL/SSL_CTX parameters can be used to control how this works: max_pipelines and split_send_fragment. max_pipelines defines the maximum number of pipelines that can ever be used in one go for a single connection. It must always be less than or equal to SSL_MAX_PIPELINES (currently defined to be 32). By default only one pipeline will be used (i.e. normal non-parallel operation). split_send_fragment defines how data is split up into pipelines. The number of pipelines used will be determined by the amount of data provided to the SSL_write call divided by split_send_fragment. For example if split_send_fragment is set to 2000 and max_pipelines is 4 then: SSL_write called with 0-2000 bytes == 1 pipeline used SSL_write called with 2001-4000 bytes == 2 pipelines used SSL_write called with 4001-6000 bytes == 3 pipelines used SSL_write_called with 6001+ bytes == 4 pipelines used split_send_fragment must always be less than or equal to max_send_fragment. By default it is set to be equal to max_send_fragment. This will mean that the same number of records will always be created as would have been created in the non-parallel case, although the data will be apportioned differently. In the parallel case data will be spread equally between the pipelines. Reviewed-by: Tim Hudson <tjh@openssl.org> |

OpenSSL 1.1.0-pre4-dev Copyright (c) 1998-2016 The OpenSSL Project Copyright (c) 1995-1998 Eric A. Young, Tim J. Hudson All rights reserved. DESCRIPTION ----------- The OpenSSL Project is a collaborative effort to develop a robust, commercial-grade, fully featured, and Open Source toolkit implementing the Secure Sockets Layer (SSLv3) and Transport Layer Security (TLS) protocols as well as a full-strength general purpose cryptographic 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. OpenSSL is descended from the SSLeay library developed by Eric A. Young and Tim J. Hudson. The OpenSSL toolkit is licensed under a dual-license (the OpenSSL license plus the SSLeay license), which means that you are free to get and use it for commercial and non-commercial purposes as long as you fulfill the conditions of both licenses. OVERVIEW -------- The OpenSSL toolkit includes: libssl.a: Provides the client and server-side implementations for SSLv3 and TLS. libcrypto.a: 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 key parameters Creation of X.509 certificates, CSRs and CRLs Calculation of message digests Encryption and decryption SSL/TLS client and server tests Handling of S/MIME signed or encrypted mail And more... INSTALLATION ------------ 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.WIN Windows INSTALL.WCE Windows CE SUPPORT ------- See the OpenSSL website www.openssl.org for details on how to obtain commercial technical support. If you have any problems with OpenSSL then please take the following steps first: - Download the current snapshot from ftp://ftp.openssl.org/snapshot/ to see if the problem has already been addressed - Remove ASM versions of libraries - Remove compiler optimisation flags If you wish to report a bug then please include the following information in any bug report: - On Unix systems: Self-test report generated by 'make report' - On other systems: OpenSSL version: output of 'openssl version -a' OS Name, Version, Hardware platform Compiler Details (name, version) - Application Details (name, version) - Problem Description (steps that will reproduce the problem, if known) - Stack Traceback (if the application dumps core) Email the report to: rt@openssl.org In order to avoid spam, this is a moderated mailing list, and it might take a day for the ticket to show up. (We also scan posts to make sure that security disclosures aren't publically posted by mistake.) Mail to this address is recorded in the public RT (request tracker) database (see https://www.openssl.org/community/index.html#bugs for details) and also forwarded the public openssl-dev mailing list. Confidential mail may be sent to openssl-security@openssl.org (PGP key available from the key servers). Please do NOT use this for general assistance or support queries. Just because something doesn't work the way you expect does not mean it is necessarily a bug in OpenSSL. You can also make GitHub pull requests. If you do this, please also send mail to rt@openssl.org with a link to the PR so that we can more easily keep track of it. HOW TO CONTRIBUTE TO OpenSSL ---------------------------- See CONTRIBUTING LEGALITIES ---------- A number of nations, in particular the U.S., restrict the use or export of cryptography. If you are potentially subject to such restrictions you should seek competent professional legal advice before attempting to develop or distribute cryptographic code.
