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.
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.
