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.
