.. Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. \*(C+ will
give a nicer C++. Capital omega is used to do unbreakable dashes and
therefore won't be available. \*(C` and \*(C' expand to `' in nroff,
nothing in troff, for use with C<>.

Escape single quotes in literal strings from groff's Unicode transform.

If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.

Avoid warning from groff about undefined register 'F'.

Title "EVP_md5 3" For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.
.nh EVP_md5, EVP_md5_sha1 \- MD5 For EVP libcrypto, -lcrypto Header "SYNOPSIS" .Vb 1 #include <openssl/evp.h> \& const EVP_MD *EVP_md5(void); const EVP_MD *EVP_md5_sha1(void); .Ve Header "DESCRIPTION" \s-1MD5\s0 is a cryptographic hash function standardized in \s-1RFC 1321\s0 and designed by Ronald Rivest.

The \s-1CMU\s0 Software Engineering Institute considers \s-1MD5\s0 unsuitable for further use since its security has been severely compromised.

Item "EVP_md5()" The \s-1MD5\s0 algorithm which produces a 128-bit output from a given input. Item "EVP_md5_sha1()" A hash algorithm of \s-1SSL\s0 v3 that combines \s-1MD5\s0 with \s-1SHA-1\s0 as described in \s-1RFC 6101.\s0 .Sp \s-1WARNING:\s0 this algorithm is not intended for non-SSL usage. Header "RETURN VALUES" These functions return a \s-1EVP_MD\s0 structure that contains the implementation of the symmetric cipher. See EVP_MD_meth_new\|(3) for details of the \s-1EVP_MD\s0 structure. Header "CONFORMING TO" \s-1IETF RFC 1321.\s0 Header "SEE ALSO" \fBevp\|(7), \fBEVP_DigestInit\|(3) Header "COPYRIGHT" Copyright 2017-2019 The OpenSSL Project Authors. All Rights Reserved.
