[openssl-users] [openssl-dev] Low level API call to digest SHA1 forbidden in FIPS mode - within openssl code

[Jeremy Farrell]

This is a question about using the OpenSSL libraries; should be in 
openssl-users, copied and reply-to'd.

I notice the assertion message mentions a header from what looks like a 
1.0.2f tree, but the references below are all to a 1.0.2g tree. I've no 
idea if this is relevant to the problem, but I wonder if this is a 
self-consistent build of the libraries.
