+All of the functions described on this page are deprecated.
+Applications should instead use L<EVP_DigestInit_ex(3)>, L<EVP_DigestUpdate(3)>
+and L<EVP_DigestFinal_ex(3)>.
+
 MD2, MD4, and MD5 are cryptographic hash functions with a 128 bit output.
 
 MD2(), MD4(), and MD5() compute the MD2, MD4, and MD5 message digest
