[openssl-users] OpenSSL v1.1.1 static library size reduction

I am using OpenSSL 1.1.1 from OpenSSL's website and trying to build OpenSSL
on a Windows 64 bit machine using Perl 64 bit version and nasm v2.13.03. I
have used the *no-shared* option in the Perl Configure to only build the
static library and the resulting size of the *libcrypto.lib* file is almost
19 MB. The *.exe* file generated is 3173 KB. RSA functionality (keypair
generation, encryption, decryption) is what we all need and as per the
need, the goal is to reduce *libcrypto.lib *to less than 3 MB. Using the
generated .exe file is not an option.
Please suggest ways to reduce the libcrypto.lib size to less than 3 MB on
this 64 bit machine keeping only RSA functionality.
 And, is it possible by any chance that the size of libcrypto.lib will be
smaller if OpenSSL is being built on a Windows 32 bit machine using a
Windows 32 bit configuration option VC-WIN32?

Thanks and Regards,
