17
18MD5 is a cryptographic hash function standardized in RFC 1321 and designed by
19Ronald Rivest.
20
3266cf58 21The CMU Software Engineering Institute considers MD5 unsuitable for further
bbda8ce9
RT
22use since its security has been severely compromised.

25
26=item EVP_md5()
27
28The MD5 algorithm which produces a 128-bit output from a given input.
29
30=item EVP_md5_sha1()
31
c2969ff6 32A hash algorithm of SSL v3 that combines MD5 with SHA-1 as described in RFC
bbda8ce9

42These functions return a B<EVP_MD> structure that contains the
43implementation of the symmetric cipher. See L<EVP_MD_meth_new(3)> for
44details of the B<EVP_MD> structure.
