-=head1 DESCRIPTION
-
-The EVP digest routines are a high level interface to message digests,
-and should be used instead of the cipher-specific functions.
-
-EVP_MD_CTX_new() allocates, initializes and returns a digest context.
-
-EVP_MD_CTX_reset() resets the digest context B<ctx>. This can be used
-to reuse an already existing context.
-
-EVP_MD_CTX_free() cleans up digest context B<ctx> and frees up the
-space allocated to it.
-
-EVP_MD_CTX_set_flags(), EVP_MD_CTX_clear_flags() and EVP_MD_CTX_test_flags()
-sets, clears and tests B<ctx> flags. See L</FLAGS> below for more information.
-
-EVP_DigestInit_ex() sets up digest context B<ctx> to use a digest
-B<type> from ENGINE B<impl>. B<ctx> must be initialized before calling this
-function. B<type> will typically be supplied by a function such as EVP_sha1().
-If B<impl> is NULL then the default implementation of digest B<type> is used.
-
-EVP_DigestUpdate() hashes B<cnt> bytes of data at B<d> into the
-digest context B<ctx>. This function can be called several times on the
-same B<ctx> to hash additional data.
-
-EVP_DigestFinal_ex() retrieves the digest value from B<ctx> and places
-it in B<md>. If the B<s> parameter is not NULL then the number of
-bytes of data written (i.e. the length of the digest) will be written
-to the integer at B<s>, at most B<EVP_MAX_MD_SIZE> bytes will be written.
-After calling EVP_DigestFinal_ex() no additional calls to EVP_DigestUpdate()
-can be made, but EVP_DigestInit_ex() can be called to initialize a new
-digest operation.
-
-EVP_MD_CTX_copy_ex() can be used to copy the message digest state from
-B<in> to B<out>. This is useful if large amounts of data are to be
-hashed which only differ in the last few bytes. B<out> must be initialized
-before calling this function.
-
-EVP_DigestInit() behaves in the same way as EVP_DigestInit_ex() except
-the passed context B<ctx> does not have to be initialized, and it always
-uses the default digest implementation.
-
-EVP_DigestFinal() is similar to EVP_DigestFinal_ex() except the digest
-context B<ctx> is automatically cleaned up.
-
-EVP_MD_CTX_copy() is similar to EVP_MD_CTX_copy_ex() except the destination
-B<out> does not have to be initialized.
-
-EVP_MD_size() and EVP_MD_CTX_size() return the size of the message digest
-when passed an B<EVP_MD> or an B<EVP_MD_CTX> structure, i.e. the size of the
-hash.
-
-EVP_MD_block_size() and EVP_MD_CTX_block_size() return the block size of the
-message digest when passed an B<EVP_MD> or an B<EVP_MD_CTX> structure.
-
-EVP_MD_type() and EVP_MD_CTX_type() return the NID of the OBJECT IDENTIFIER
-representing the given message digest when passed an B<EVP_MD> structure.
-For example EVP_MD_type(EVP_sha1()) returns B<NID_sha1>. This function is
-normally used when setting ASN1 OIDs.
-
-EVP_MD_CTX_md_data() return the digest method private data for the passed
-B<EVP_MD_CTX>.
-The space is allocated by OpenSSL and has the size originally set with
-EVP_MD_meth_set_app_datasize().
-
-EVP_MD_CTX_md() returns the B<EVP_MD> structure corresponding to the passed
-B<EVP_MD_CTX>.
-
-EVP_MD_pkey_type() returns the NID of the public key signing algorithm associated
-with this digest. For example EVP_sha1() is associated with RSA so this will
-return B<NID_sha1WithRSAEncryption>. Since digests and signature algorithms
-are no longer linked this function is only retained for compatibility
-reasons.
-
-EVP_md2(), EVP_md5(), EVP_sha1(), EVP_sha224(), EVP_sha256(),
-EVP_sha384(), EVP_sha512(), EVP_mdc2(), EVP_ripemd160(), EVP_blake2b512(), and
-EVP_blake2s256() return B<EVP_MD> structures for the MD2, MD5, SHA1, SHA224,
-SHA256, SHA384, SHA512, MDC2, RIPEMD160, BLAKE2b-512, and BLAKE2s-256 digest
-algorithms respectively.
-
-EVP_md_null() is a "null" message digest that does nothing: i.e. the hash it
-returns is of zero length.
-
-EVP_get_digestbyname(), EVP_get_digestbynid() and EVP_get_digestbyobj()
-return an B<EVP_MD> structure when passed a digest name, a digest NID or
-an ASN1_OBJECT structure respectively.
-
-=head1 FLAGS
-
-EVP_MD_CTX_set_flags(), EVP_MD_CTX_clear_flags() and EVP_MD_CTX_test_flags()
-can be used the manipulate and test these B<EVP_MD_CTX> flags:
-
-=over 4
-
-=item EVP_MD_CTX_FLAG_ONESHOT
-
-This flag instructs the digest to optimize for one update only, if possible.
-
-=for comment EVP_MD_CTX_FLAG_CLEANED is internal, don't mention it
-
-=for comment EVP_MD_CTX_FLAG_REUSE is internal, don't mention it
-
-=for comment We currently avoid documenting flags that are only bit holder:
-EVP_MD_CTX_FLAG_NON_FIPS_ALLOW, EVP_MD_CTX_FLAGS_PAD_*
-
-=item EVP_MD_CTX_FLAG_NO_INIT
-
-This flag instructs EVP_DigestInit() and similar not to initialise the
-implementation specific data.
-
-=item EVP_MD_CTX_FLAG_FINALISE
-
-Some functions such as EVP_DigestSign only finalise copies of internal
-contexts so additional data can be included after the finalisation call.
-This is inefficient if this functionality is not required, and can be
-disabled with this flag.

-
-=head1 RETURN VALUES
-
-EVP_DigestInit_ex(), EVP_DigestUpdate() and EVP_DigestFinal_ex() return 1 for
-success and 0 for failure.
-
-EVP_MD_CTX_copy_ex() returns 1 if successful or 0 for failure.
-
-EVP_MD_type(), EVP_MD_pkey_type() and EVP_MD_type() return the NID of the
-corresponding OBJECT IDENTIFIER or NID_undef if none exists.
-
-EVP_MD_size(), EVP_MD_block_size(), EVP_MD_CTX_size() and
-EVP_MD_CTX_block_size() return the digest or block size in bytes.
-
-EVP_md_null(), EVP_md2(), EVP_md5(), EVP_sha1(),
-EVP_mdc2(), EVP_ripemd160(), EVP_blake2b512(), and EVP_blake2s256() return
-pointers to the corresponding EVP_MD structures.
-
-EVP_get_digestbyname(), EVP_get_digestbynid() and EVP_get_digestbyobj()
-return either an B<EVP_MD> structure or NULL if an error occurs.
-
-=head1 NOTES
-
-The B<EVP> interface to message digests should almost always be used in
-preference to the low level interfaces. This is because the code then becomes
-transparent to the digest used and much more flexible.
-
-New applications should use the SHA2 digest algorithms such as SHA256.
-The other digest algorithms are still in common use.
-
-For most applications the B<impl> parameter to EVP_DigestInit_ex() will be
-set to NULL to use the default digest implementation.
-
-The functions EVP_DigestInit(), EVP_DigestFinal() and EVP_MD_CTX_copy() are
-obsolete but are retained to maintain compatibility with existing code. New
-applications should use EVP_DigestInit_ex(), EVP_DigestFinal_ex() and
-EVP_MD_CTX_copy_ex() because they can efficiently reuse a digest context
-instead of initializing and cleaning it up on each call and allow non default
-implementations of digests to be specified.
-
-If digest contexts are not cleaned up after use,
-memory leaks will occur.
-
-EVP_MD_CTX_size(), EVP_MD_CTX_block_size(), EVP_MD_CTX_type(),
-EVP_get_digestbynid() and EVP_get_digestbyobj() are defined as
-macros.
-
-
-=head1 EXAMPLE
-
-This example digests the data "Test Message\n" and "Hello World\n", using the
-digest name passed on the command line.
-
- #include <stdio.h>
- #include <openssl/evp.h>
-
- main(int argc, char *argv[])
- {
- EVP_MD_CTX *mdctx;
- const EVP_MD *md;
- char mess1[] = "Test Message\n";
- char mess2[] = "Hello World\n";
- unsigned char md_value[EVP_MAX_MD_SIZE];
- int md_len, i;
-
- if(!argv[1]) {
- printf("Usage: mdtest digestname\n");
- exit(1);
- }
-
- md = EVP_get_digestbyname(argv[1]);
-
- if(!md) {
- printf("Unknown message digest %s\n", argv[1]);
- exit(1);
- }
-
- mdctx = EVP_MD_CTX_new();
- EVP_DigestInit_ex(mdctx, md, NULL);
- EVP_DigestUpdate(mdctx, mess1, strlen(mess1));
- EVP_DigestUpdate(mdctx, mess2, strlen(mess2));
- EVP_DigestFinal_ex(mdctx, md_value, &md_len);
- EVP_MD_CTX_free(mdctx);
-
- printf("Digest is: ");
- for (i = 0; i < md_len; i++)
- printf("%02x", md_value[i]);
- printf("\n");
-
- exit(0);
- }

-
-=head1 HISTORY
-
-B<EVP_MD_CTX> became opaque in OpenSSL 1.1. Consequently, stack
-allocated B<EVP_MD_CTX>s are no longer supported.
-
-EVP_MD_CTX_create() and EVP_MD_CTX_destroy() were renamed to
-EVP_MD_CTX_new() and EVP_MD_CTX_free() in OpenSSL 1.1.
-
-The link between digests and signing algorithms was fixed in OpenSSL 1.0 and
-later, so now EVP_sha1() can be used with RSA and DSA. The legacy EVP_dss1()
-was removed in OpenSSL 1.1.0
