Need help with a rsaenh bug

[Daniel Jeliński]

It is definitely valid to call CryptDecrypt multiple times with the same
key. Calls with Final = FALSE change the internal state of the key, calls
with Final = TRUE restore the initial state. Subsequent calls with Final =
TRUE should return the same result.

Your testcase fails because CryptDecrypt changes the value of dwLen, which
you do not restore before calling the function again.

Daniel
