It says how to do it right in the comments, namely the block of comments
that ends with
* MD5 example:
*
* #define DATA_ORDER_IS_LITTLE_ENDIAN
*
* #define HASH_LONG MD5_LONG
* #define HASH_LONG_LOG2 MD5_LONG_LOG2
* #define HASH_CTX MD5_CTX
* #define HASH_CBLOCK MD5_CBLOCK
* #define HASH_LBLOCK MD5_LBLOCK
* #define HASH_UPDATE MD5_Update
* #define HASH_TRANSFORM MD5_Transform
* #define HASH_FINAL MD5_Final
* #define HASH_BLOCK_HOST_ORDER md5_block_host_order
* #define HASH_BLOCK_DATA_ORDER md5_block_data_order
*
followed by
#include md32_common.h
If you just want to hash some data, have a look at the docs at
(http://www.openssl.org/docs/crypto/EVP_DigestInit.html#)

Subject: Indirection in Digests
Hi , I am new to openSSL. I am looking at the code in md32_common.h file
which has a single method HASH_UPDATE(..) for MD5 and SHA-1 etc. I tried
to
figure out how does the program knows which digest to use at run time but
failed? any help would be highly appreciated.
Thanks,
Imran.
