CRYPTLIB MANUAL PDF

The technical reference manual covers the design and internals of cryptlib itself. cryptlib features 11 Performance cryptlib is re-entrant and completely thread-safe . This interface is more “Delphi-like” than , which is “C-like”. for DelphiCryptlib, but you should have read Peter Gutman’s cryptlib manual before. The cryptlib manual [23, page 35] states that the programmer is required to check that each function returns CRYPT_OK, and that the wrong code shown above.

This is to allow a central consistent version to be maintained.

All standard error handling from cryptlib is done manula Exception handling in Delphi. Note that decoupling the software from the user, for example by running in a SaaS configuration, does not exempt you from these requirements.

In addition the easy-to-use high-level routines allow for the exchange of encrypted or signed messages or the establishment of secure communications channels with a minimum of programming overhead.

DelphiCryptlib.pas

The user manual cryptljb intended for everyday cryptlib use and contains detailed documentation on every aspect of cryptlib’s functionality. The current cryptlib release is cryptlib 3.

Peter Gutman ‘s Cryptlib binaries version 3. These routines provide an unprecedented level of performance, in most cases running faster than expensive, specialised encryption hardware designed to perform the same task.

– Objectoriented Delphi interface for Peter Gutman’s Cryptlib library

This interface is more “Delphi-like” than cryptlib. Wolfgang Cryptlig has a web page with Visual Basic and Delphi add-ons for cryptlib that provide more VB- and Delphi-like interfaces than the standard one, as well as sample code in VB and Delphi. There is a very low volume mailing list available that covers cryptlib development and usage and implementation details.

Most of the core algorithms used in cryptlib have been implemented in assembly language in order to provide the maximum possible performance, and maual take advantage of crypto hardware acceleration facilities present in some CPUs such as the Via C3 family. Exact terms are given at the bottom of this page. Please use this with the latest CL In addition, mabual is free for use in low-cost, non-open-source applications such as shareware, and for personal and research use.

The application programming interface API serves as an interface to a range of plug-in encryption modules that allow encryption algorithms to be added in a fairly transparent manner, so that adding a new algorithm or replacing an existing software implementation with custom encryption hardware can be done without any trouble.

You may use the “F1”-key when editing your source to popup online help on any DelphiCryptlib object, method or property.

Before working with it, you should read at least the Installation section of the manual, which covers details on installing the software on different platforms under Unix you need to unzip with the -a option. In addition the author reserves the right to grant free licenses for commercial use in special cases for example where there is a general benefit to the publiccontact the author for details if you think you qualify. General questions on cryptlib are answered in the cryptlib FAQ.

In addition logical errors such as, for example, a key exchange function being called in the wrong sequence, are checked for and identified. Any software you create with this code may not be merely a set or subset of cryptlib, with or without minor added functionality or a different interface.

Any large-scale commercial mznual of cryptlib requires a license. In addition cryptlib itself is multithreaded so that computationally intensive internal operations take place in the background without impacting the performance of the calling application.

In particular you can’t distribute cryptlib or any modified form of it as your own encryption product. Peter Gutman ‘s Cryptlib version 3.

The standardised API allows any of the algorithms and modes supported by cryptlib to be used with a minimum of coding effort. For information on commercial cryphlib, there is a cryptlib brochure available in PDF format. Delphi interface cdyptlib generated from cryptlib. To subscribe, send mail to the list administrator with the word “subscribe” in the message body.

On initialisation it performs extensive self-testing against test data from encryption standards documents, and the APIs check each parameter and function call for errors before any actions are performed, with error reporting down to the level of individual parameters.

This allows cryptlib to be used in freeware and shareware applications, for evaluation and research purposes, and for non-revenue-generating or personal use kanual charge. The technical reference manual covers the design and internals of cryptlib itself, including the cryptlib security model and security mechanisms that protect every part of cryptlib. Most cryptlib attributes are defined as properties in DelphiCryptlib.

In addition the technical manual provides a wealth of background information to help users understand the security foundations on which cryptlib is built. Because it is thread-safe, lengthy cryptlib operations can be run in the background if required while other processing is performed in the foreground.

This is to stop people adding their own wrappers and selling it as “their” encryption product. Look for sample code showing how to use Cryptlib. Peter Gutman ‘s cryptlib manual for version 3. Msnual should receive a reply informing you that you’ve been added to the list. You can also get the documentation ,anual Windows help format conversion performed by David Kelvin. The essential objects defined in DelphiCryptlib.

And you know, if you download the source, you do it on your own risk.
