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.

If you’re unable to comply with the above license then the following, alternate usage conditions apply:. If Cert is a TCryptCert variable, you may use:.

This allows cryptlib to be used in freeware and shareware applications, for evaluation and crypltib purposes, and for non-revenue-generating or personal use without charge. Please use this with the latest CL These routines provide an unprecedented level of performance, in most cases running faster than expensive, specialised encryption hardware designed to perform the same task.

And you know, if you download the source, you do it on your own risk. This is to stop people adding their own wrappers and selling it as “their” encryption product. Wolfgang Gothier has a web page with Visual Ctyptlib 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.

- Objectoriented Delphi interface for Peter Gutman’s Cryptlib library

Because it is thread-safe, manuall cryptlib operations can be run in the background if required while other processing is performed in the foreground. Please report problems and errors to problems cryptlib.

The essential objects defined in DelphiCryptlib. If you make any changes to the code, you should send a copy of the changes to the author to allow them to be integrated into the code.

DelphiCryptlib.pas

There is a very low volume mailing list available that covers cryptlib development and usage and implementation details. The GPL-compatible license a.

Peter Gutman ‘s Cryptlib binaries version 3. Delphi interface file generated from cryptlib. 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.

You can also get the documentation in Windows help format conversion performed by David Kelvin. Any software you create with this code may not be merely a set or subset of cryptlib, with or manuzl minor added functionality or a different interface. In mqnual cryptlib itself is multithreaded so that computationally intensive internal operations take place in the background without impacting the performance of the calling application.

In addition the crypptlib manual provides a wealth of background information to help users understand the security foundations on which cryptlib is built. An archive of older mailing-list postings is also available.

DelphiCryptlib is an objectoriented wrapper for the functions defined in cryptlib. Peter Gutman ‘s Cryptlib version 3.

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

A good overview and background behind the Sleepycat licensewhich also applies for cryptlib, is also available. For details of the implementation have a look into the crjptlib part of the DelphiCryptlib.

The user manual is intended for everyday cryptlib use and contains detailed documentation on every aspect of cryptlib’s functionality. I can’t give you any support and any warranties are explicitly disclaimed.

To subscribe, send mail to the list administrator with the word “subscribe” in the message body.

You may use the “F1”-key when editing your source to popup online help on any DelphiCryptlib object, method or property. You don’t have to check the return codes after every cryptlib call.

In most cases the code needed to secure an application can be crtptlib and pasted directly from the appropriate section of the manual, avoiding the need to learn yet another programming API.

Most cryptlib attributes are defined as properties in DelphiCryptlib. 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.

The standardised API allows any of the algorithms and modes supported by cryptlib to be used with a minimum of coding effort.
