.SH NAME
EVP_md2
\&\- MD2 For EVP
.SH SYNOPSIS
.IX Header "SYNOPSIS"
.Vb 1
\& #include <openssl/evp.h>
\&
\& const EVP_MD *EVP_md2(void);
.Ve
.SH DESCRIPTION
.IX Header "DESCRIPTION"
MD2 is a cryptographic hash function standardized in RFC 1319 and designed by
Ronald Rivest. This implementation is only available with the legacy provider.
.IP \fBEVP_md2()\fR 4
.IX Item "EVP_md2()"
The MD2 algorithm which produces a 128\-bit output from a given input.
.SH NOTES
.IX Header "NOTES"
Developers should be aware of the negative performance implications of
calling this function multiple times and should consider using
\&\fBEVP_MD_fetch\fR\|(3) with \fBEVP_MD\-MD2\fR\|(7) instead.
See "Performance" in \fBcrypto\fR\|(7) for further information.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
These functions return a \fBEVP_MD\fR structure that contains the
implementation of the message digest. See \fBEVP_MD_meth_new\fR\|(3) for
details of the \fBEVP_MD\fR structure.
