Hi, I have Windows XP SP3 and Delphi 5 and VCL code package version: 9.1.216
the problem is that when I use the "TelHashFunction.Create(SB_ALGORITHM_DGST_SHA1) " function, it falls telling me the error "Access violation", but this does not always happen but it happens very often.
Sometimes I spend two or three times to get it right. This message is sent at runtime with Delphi, but when I run the program it just falls without any message.
Why this error is due?

The common reason for such errors is a memory corruption in your program. It can be completely unrelated to SecureBlackbox. The easiest way to prove or deny this hypothesis is to move your hash creation code into the test case and see if the problem persists. If it goes away, then you should look for possible places of memory corruption in your code.


Sincerely yours
Eugene Mayevski
