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.

You don’t have to check the return codes after every cryptlib call. And you know, if you download the source, you do it on your own risk. If Cert is a TCryptCert variable, you may use:.
DelphiCryptlib is an objectoriented wrapper for the functions defined in cryptlib. In addition, cryptlib is free for use in low-cost, non-open-source applications such as shareware, and for personal and research use.
– Objectoriented Delphi interface for Peter Gutman’s Cryptlib library
You may use the “F1”-key when editing your source to popup online help on any DelphiCryptlib object, method or property. The essential objects defined in DelphiCryptlib. All standard error handling from cryptlib is done via Exception handling in Delphi.
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. Cry;tlib should receive a reply informing you that you’ve been added to the list. I can’t give you any support and any warranties are explicitly disclaimed. The GPL-compatible license a. To subscribe, send mail to mqnual list administrator with the word “subscribe” in the message body.
If you’re unable to comply with the above license then the following, alternate usage conditions apply:.
For details of the implementation have a look into the interface part of the DelphiCryptlib. In addition the author reserves the right to grant free licenses cryyptlib 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.
Peter Gutman ‘s Cryptlib version 3.
These routines provide an unprecedented level of kanual, in most cases running faster than expensive, specialised encryption hardware designed to perform the same task. In addition cryptlib itself is multithreaded so that computationally intensive internal crryptlib take place in the background without impacting cryptlub performance of the calling application.
This allows cryptlib to be used in freeware and shareware applications, for evaluation and research purposes, and for non-revenue-generating or personal use without charge. The current cryptlib release is cryptlib 3. In most cases the code needed to secure an application can be cut and pasted directly from the appropriate section of the manual, avoiding the need to learn yet another programming API.
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 ceyptlib reporting down to the level of individual parameters.
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 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. A good overview and background behind the Sleepycat licensewhich also applies for cryptlib, is also available. Note that decoupling the software from the user, for example by running in a SaaS configuration, does not exempt you from these requirements.
This is to stop people cryprlib their own wrappers and selling it as “their” encryption product. For information on commercial use, there is a cryptlib brochure available crjptlib PDF format.
The user manual is intended for everyday cryptlib use and contains detailed documentation on every aspect of cryptlib’s functionality. Peter Gutman ‘s cryptlib manual for version 3.
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. The user manual concludes with a reference section covering the various cryptlib API functions, constants, and data types. This interface is more “Delphi-like” than cryptlib. In particular manua can’t distribute cryptlib or any modified form of it as your own encryption product.
