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.

– Objectoriented Delphi interface for Peter Gutman’s Cryptlib library
Please use this with the latest CL Peter Gutman ‘s cryptlib manual for version 3. A Helpfile is available for DelphiCryptlib, but you should have read Peter Gutman’s cryptlib manual before. General questions on cryptlib are answered in the cryptlib FAQ. Peter Gutman ‘s Cryptlib version 3. Delphi interface file generated from cryptlib. In particular you can’t distribute cryptlib or any modified form of it as your own encryption product.
And you know, if you download the source, you do it on your own risk. In addition logical errors such as, for example, a key exchange function being called in the wrong sequence, are checked for and identified. Please report problems and errors to problems cryptlib. You should receive a reply informing you that you’ve been added to cryptkib list. 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.
Most cryptlib attributes are defined as properties in DelphiCryptlib. This is to stop people adding their own wrappers and selling it as “their” encryption product. In addition the author reserves the right to grant free licenses for commercial use in special cases for example where there cryptlbi a general benefit to the publiccontact the author for details if you think you qualify. To subscribe, send mail to the list administrator with the cruptlib “subscribe” in the message body.
Any large-scale commercial use of cryptlib requires a license. The GPL-compatible license a. Because it is thread-safe, lengthy cryptlib operations can be run in the background if required while other processing is performed in the foreground. Most of the core algorithms used in cryptlib have been implemented in assembly language in order to provide the maximum possible performance, and will take advantage of crypto hardware acceleration facilities present in some CPUs such as the Via C3 family.
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.
You don’t have to check the return codes after every cryptlib call.
Anyone who has a support contract for cryptlib version 3. If Cert is a TCryptCert variable, you may use:. 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 crtptlib messages or the establishment of secure communications channels with a minimum of programming overhead. For details of the implementation have a look into the interface part of the DelphiCryptlib.
An archive of older mailing-list postings is also available. The user manual is intended for everyday cryptlib use and contains detailed documentation on every aspect of cryptlib’s functionality. For information on commercial use, there is a cryptlib brochure available in PDF format.
If you’re unable to comply with the above license then the following, alternate usage conditions apply:. The application programming interface API serves as an interface to a range of plug-in encryption modules that allow encryption algorithms to be xryptlib 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. The standardised API allows any of the algorithms and modes supported by cryptlib to be used with a minimum of coding effort.
Wolfgang Gothier 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.
mxnual You can also get the documentation in Windows help format conversion performed by David Kelvin. The current cryptlib release is cryptlib 3. This is to allow a central consistent version to be maintained.

All standard error handling from cryptlib is done via Exception handling in Delphi. Peter Gutman ‘s Cryptlib binaries version 3.
DelphiCryptlib is an objectoriented wrapper for the functions defined cryptliv 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.
There is a very low volume mailing list available that covers cryptlib development and usage and implementation details. In addition manuaal technical manual provides a wealth of background information to help users understand the security foundations on which cryptlib is built.
I can’t give you any support and any warranties are explicitly disclaimed. You may use the “F1”-key when editing your source to popup online help on any DelphiCryptlib object, method or property. 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.
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. Anyone without a support contract will no longer be able to receive support for 3.
