| 50 | commercial use" means any revenue-generating purpose such as use for
|
|---|
| 51 | company-internal purposes, or use of cryptlib in an application or product,
|
|---|
| 52 | with a total gross revenue of over US$5,000. This allows cryptlib to be
|
|---|
| 53 | used in freeware and shareware applications, for evaluation and research
|
|---|
| 54 | purposes, and for non-revenue-generating or personal use without charge. In
|

| 55 | addition the author reserves the right to grant free licenses for commercial
|
|---|
| 56 | use in special cases (for example where there is a general benefit to the
|
