From the OPENSL docs:
//---------------------
New applications should use the SHA2 digest algorithms such as SHA256. The
other digest algorithms are still in common use.
For most applications the impl parameter to EVP_DigestInit_ex() will be
set to NULL to use the default digest implementation.
The functions EVP_DigestInit(), EVP_DigestFinal() and EVP_MD_CTX_copy()
are obsolete but are retained to maintain compatibility with existing
code. New applications should use EVP_DigestInit_ex(),
EVP_DigestFinal_ex() and EVP_MD_CTX_copy_ex() because they can efficiently
reuse a digest context instead of initializing and cleaning it up on each
call and allow non default implementations of digests to be specified.
In OpenSSL 0.9.7 and later if digest contexts are not cleaned up after
use memory leaks will occur.
