Hi there,

  I want to use some bcrypt functions

BCryptCreateHash
BCryptHashData
BCryptFinishHash
BCryptDestroyHash
BCryptGenRandom
and
CryptBinaryToStringA and CryptStringToBinaryA in a multithreading
application.

  For bcrypt functions, I run BCryptOpenAlgorithmProvider once for
each thread and get a handle that will use with the other functions in
the respective thread.

  Functions CryptBinaryToStringA and CryptStringToBinaryA I use them
normally, thinking they are synchronous and does not require any
interlocking mechanism. Function arguments are not mixed.

  Am I right ? Thank you.
