EVP_md2(3ssl)

EVP_md23ssl

Md2 for evp

Usage

 #include <openssl/evp.h>
 const EVP_MD *EVP_md2(void);

Overview

MD2 is a cryptographic hash function standardized in RFC 1319 and designed by Ronald Rivest. This implementation is only available with the legacy provider.

EVP_md2()

The MD2 algorithm which produces a 128-bit output from a given input.

Notes

Developers should be aware of the negative performance implications of calling this function multiple times and should consider using EVP_MD_fetch(3) with EVP_MD-MD2(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.
