EVP_md5, EVP_md5_sha1 - MD5 For EVP
 #include <openssl/evp.h>
 const EVP_MD *EVP_md5(void);
 const EVP_MD *EVP_md5_sha1(void);
MD5 is a cryptographic hash function standardized in RFC 1321 and designed by
  Ronald Rivest.
The CMU Software Engineering Institute considers MD5 unsuitable
    for further use since its security has been severely compromised.
  - EVP_md5()
- The MD5 algorithm which produces a 128-bit output from a given input.
- EVP_md5_sha1()
- A hash algorithm of SSL v3 that combines MD5 with SHA-1 as described in
      RFC 6101.
    WARNING: this algorithm is not intended for non-SSL usage. 
Developers should be aware of the negative performance implications of calling
  these functions multiple times and should consider using
  EVP_MD_fetch(3) with EVP_MD-MD5(7) or EVP_MD-MD5-SHA1(7)
  instead. See "Performance" in crypto(7) for further
  information.
These functions return a EVP_MD structure that contains the
  implementation of the message digest. See EVP_MD_meth_new(3) for
  details of the EVP_MD structure.
