EVP_md53ssl
Md5 for evp
Usage
#include <openssl/evp.h>const EVP_MD *EVP_md5(void);const EVP_MD *EVP_md5_sha1(void);
Overview
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.
Notes
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.
Return values
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.
