Update history of cryptlib
v3.0 (May, 22. 2007)
The Unix randomness-gathering code now checks for and uses EGD/PRNGD if available.
Requirement that cryptlib be built via a network share under Windows is removed.
HTTP keyset access: server URL is given when keyset is opened as with other types, and a key ID is given when reading individual keys.

Any large-scale commercial use of cryptlib requires a license. "Large-scale commercial use" means any revenue-generating purpose such as use for company- internal purposes, or use of cryptlib in an application or product, with a total gross revenue of over US$5,000. 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. 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 public), contact the author for details if you think you qualify.
