Excellent!  `SBS` works perfectly to me.  Thank you.

I'm debugging BCrypt hash in "crypton" which fails a test case only on
arm64 architecture. I suspect that Context of blowfish created on
arm64 is differrent from that on x86_64. `SBS` tells me that they are
actually different. So, a bug exists in the functions to create
Context.  I can take a step forward now.
