Log Message:
rename {MD5,HMAC} to openssl_{MD5,HMAC}. Also add man pages for openssl_MD2
and openssl_MD4 to avoid conflicts with case-preserving but case-insensitive
filesystems and the corresponding libc lower case man pages.

+.IX Header "DESCRIPTION"
+\&\s-1HMAC\s0 is a \s-1MAC \s0(message authentication code), i.e. a keyed hash
+function used for message authentication, which is based on a hash
+function.
+.PP
+\&\s-1\fIHMAC\s0()\fR computes the message authentication code of the \fBn\fR bytes at
+\&\fBd\fR using the hash function \fBevp_md\fR and the key \fBkey\fR which is
+\&\fBkey_len\fR bytes long.
+.PP
+It places the result in \fBmd\fR (which must have space for the output of
+the hash function, which is no more than \fB\s-1EVP_MAX_MD_SIZE\s0\fR bytes).
+If \fBmd\fR is \s-1NULL,\s0 the digest is placed in a static array. The size of
+the output is placed in \fBmd_len\fR, unless it is \fB\s-1NULL\s0\fR. Note: passing a \s-1NULL\s0
+value for \fBmd\fR to use the static array is not thread safe.
+.PP
+\&\fBevp_md\fR can be \fIEVP_sha1()\fR, \fIEVP_ripemd160()\fR etc.
+.PP
+\&\fIHMAC_CTX_new()\fR creates a new \s-1HMAC_CTX\s0 in heap memory.
+.PP
+\&\fIHMAC_CTX_reset()\fR zeroes an existing \fB\s-1HMAC_CTX\s0\fR and associated
+resources, making it suitable for new computations as if it was newly
+created with \fIHMAC_CTX_new()\fR.
+.PP
+\&\fIHMAC_CTX_free()\fR erases the key and other data from the \fB\s-1HMAC_CTX\s0\fR,
+releases any associated resources and finally frees the \fB\s-1HMAC_CTX\s0\fR
+itself.
+.PP
+The following functions may be used if the message is not completely
+stored in memory:
+.PP
+\&\fIHMAC_Init()\fR initializes a \fB\s-1HMAC_CTX\s0\fR structure to use the hash
+function \fBevp_md\fR and the key \fBkey\fR which is \fBkey_len\fR bytes
+long. It is deprecated and only included for backward compatibility
+with OpenSSL 0.9.6b.
+.PP
+\&\fIHMAC_Init_ex()\fR initializes or reuses a \fB\s-1HMAC_CTX\s0\fR structure to use the hash
+function \fBevp_md\fR and key \fBkey\fR. If both are \s-1NULL \s0(or \fBevp_md\fR is the same
+as the previous digest used by \fBctx\fR and \fBkey\fR is \s-1NULL\s0) the existing key is
+reused. \fBctx\fR must have been created with \fIHMAC_CTX_new()\fR before the first use
+of an \fB\s-1HMAC_CTX\s0\fR in this function. \fBN.B. \f(BIHMAC_Init()\fB had this undocumented
+behaviour in previous versions of OpenSSL \- failure to switch to \f(BIHMAC_Init_ex()\fB
+in programs that expect it will cause them to stop working\fR.
+.PP
+\&\fB\s-1NOTE:\s0\fR If \fIHMAC_Init_ex()\fR is called with \fBkey\fR \s-1NULL\s0 and \fBevp_md\fR is not the
+same as the previous digest used by \fBctx\fR then an error is returned
+because reuse of an existing key with a different digest is not supported.
+.PP
+\&\fIHMAC_Update()\fR can be called repeatedly with chunks of the message to
+be authenticated (\fBlen\fR bytes at \fBdata\fR).
+.PP
+\&\fIHMAC_Final()\fR places the message authentication code in \fBmd\fR, which
+must have space for the hash function output.
+.PP
+\&\fIHMAC_CTX_copy()\fR copies all of the internal state from \fBsctx\fR into \fBdctx\fR.
+.PP
+\&\fIHMAC_CTX_set_flags()\fR applies the specified flags to the internal EVP_MD_CTXs.
+These flags have the same meaning as for \fIEVP_MD_CTX_set_flags\fR\|(3).
+.PP
+\&\fIHMAC_CTX_get_md()\fR returns the \s-1EVP_MD\s0 that has previously been set for the
+supplied \s-1HMAC_CTX.\s0
+.SH "RETURN VALUES"
+.IX Header "RETURN VALUES"
+\&\s-1\fIHMAC\s0()\fR returns a pointer to the message authentication code or \s-1NULL\s0 if
+an error occurred.
+.PP
+\&\fIHMAC_CTX_new()\fR returns a pointer to a new \fB\s-1HMAC_CTX\s0\fR on success or
+\&\fB\s-1NULL\s0\fR if an error occurred.
+.PP
+\&\fIHMAC_CTX_reset()\fR, \fIHMAC_Init_ex()\fR, \fIHMAC_Update()\fR, \fIHMAC_Final()\fR and
+\&\fIHMAC_CTX_copy()\fR return 1 for success or 0 if an error occurred.
+.PP
+\&\fIHMAC_CTX_get_md()\fR return the \s-1EVP_MD\s0 previously set for the supplied \s-1HMAC_CTX\s0 or

+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+\&\s-1MD2, MD4,\s0 and \s-1MD5\s0 are cryptographic hash functions with a 128 bit output.
+.PP
+\&\s-1\fIMD2\s0()\fR, \s-1\fIMD4\s0()\fR, and \s-1\fIMD5\s0()\fR compute the \s-1MD2, MD4,\s0 and \s-1MD5\s0 message digest
+of the \fBn\fR bytes at \fBd\fR and place it in \fBmd\fR (which must have space
+for \s-1MD2_DIGEST_LENGTH\s0 == \s-1MD4_DIGEST_LENGTH\s0 == \s-1MD5_DIGEST_LENGTH\s0 == 16
+bytes of output). If \fBmd\fR is \s-1NULL,\s0 the digest is placed in a static
+array.
+.PP
+The following functions may be used if the message is not completely
+stored in memory:
+.PP
+\&\fIMD2_Init()\fR initializes a \fB\s-1MD2_CTX\s0\fR structure.
+.PP
+\&\fIMD2_Update()\fR can be called repeatedly with chunks of the message to
+be hashed (\fBlen\fR bytes at \fBdata\fR).
+.PP
+\&\fIMD2_Final()\fR places the message digest in \fBmd\fR, which must have space
+for \s-1MD2_DIGEST_LENGTH\s0 == 16 bytes of output, and erases the \fB\s-1MD2_CTX\s0\fR.
+.PP
+\&\fIMD4_Init()\fR, \fIMD4_Update()\fR, \fIMD4_Final()\fR, \fIMD5_Init()\fR, \fIMD5_Update()\fR, and
+\&\fIMD5_Final()\fR are analogous using an \fB\s-1MD4_CTX\s0\fR and \fB\s-1MD5_CTX\s0\fR structure.
+.PP
+Applications should use the higher level functions
+\&\fIEVP_DigestInit\fR\|(3)
+etc. instead of calling the hash functions directly.
+.SH "NOTE"
+.IX Header "NOTE"
+\&\s-1MD2, MD4,\s0 and \s-1MD5\s0 are recommended only for compatibility with existing
+applications. In new applications, \s-1SHA\-1\s0 or \s-1RIPEMD\-160\s0 should be
+preferred.
+.SH "RETURN VALUES"
+.IX Header "RETURN VALUES"
+\&\s-1\fIMD2\s0()\fR, \s-1\fIMD4\s0()\fR, and \s-1\fIMD5\s0()\fR return pointers to the hash value.
+.PP
+\&\fIMD2_Init()\fR, \fIMD2_Update()\fR, \fIMD2_Final()\fR, \fIMD4_Init()\fR, \fIMD4_Update()\fR,
+\&\fIMD4_Final()\fR, \fIMD5_Init()\fR, \fIMD5_Update()\fR, and \fIMD5_Final()\fR return 1 for
+success, 0 otherwise.
