[stunnel-users] CAPI_GET_KEY:cryptacquirecontext error

 No luck. The downloaded stunnel 5.56 behaves exactly as 5.48 - it
logs  "CAPI_GET_KEY:cryptacquirecontext
error" or "CAPI_CTX_SET_PROVNAME:cryptacquirecontext error" (depending on
selected csp_name and csp_type)
Did anyone succeed in getting stunnel+capi work for TLS 1.2 ?
Maybe some OpenSSL configuration commands could help... But I cannot
imagine what.
And I did see "You also need to disable TLS 1.2 or later because the
CryptoAPI engine currently does not support PSS" phrase in sample
stunnel.conf - isn't it an obsolete restriction?

Thanks in advance,
