To call the CryptoSys PKI functions
from a classic Visual Basic VB6 project or VBA application,
just add the module basCrPKI.bas to your project
(VBA users should delete the first line Attribute VB_Name = "basCrPKI").
The VB6 functions work in the same way as you would call the Win32 API functions from VB6. You must use the correct variable types and must pre-dimension strings and byte arrays that are to receive output or you will suffer the wrath of the great god Gee-pee-eff.
For examples, see the test code
provided in the distribution in the folder
C:\Program Files\CryptoSysPKI\VB6.
