+.Sh DESCRIPTION
+The RMD160 functions implement the 160-bit RIPE message digest hash algorithm
+(RMD-160).
+RMD-160 is used to generate a condensed representation
+of a message called a message digest.
+The algorithm takes a
+message less than 2^64 bits as input and produces a 160-bit digest
+suitable for use as a digital signature.
+.Pp
+The RMD160 functions are considered to be more secure than the
+.Xr md4 3
+and
+.Xr md5 3
+functions and at least as secure as the
+.Xr sha1 3
+function.
+All share a similar interface.
+.Pp
+The
+.Fn RMD160Init
+function initializes a RMD160_CTX
+.Ar context
+for use with
+.Fn RMD160Update ,
+and
+.Fn RMD160Final .
+The
+.Fn RMD160Update
+function adds
+.Ar data
+of length
+.Ar nbytes
+to the RMD160_CTX specified by
+.Ar context .
+.Fn RMD160Final
+is called when all data has been added via
+.Fn RMD160Update
+and stores a message digest in the
+.Ar digest
+parameter.
+When a null pointer is passed to
+.Fn RMD160Final
+as first argument only the final padding will be applied and the
+current context can still be used with
+.Fn RMD160Update .
+.Pp
+The
+.Fn RMD160Transform
+function is used by
+.Fn RMD160Update
+to hash 512-bit blocks and forms the core of the algorithm.
+Most programs should use the interface provided by
+.Fn RMD160Init ,
+.Fn RMD160Update
+and
+.Fn RMD160Final
+instead of calling
+.Fn RMD160Transform
+directly.
+.Pp
+The
+.Fn RMD160End
+function is a front end for
+.Fn RMD160Final
+which converts the digest into an
+.Tn ASCII
+representation of the 160 bit digest in hexadecimal.
+.Pp
+The
+.Fn RMD160File
+function calculates the digest for a file and returns the result via
+.Fn RMD160End .
+If
+.Fn RMD160File
+is unable to open the file a NULL pointer is returned.
+.Pp
+The
+.Fn RMD160Data
+function
+calculates the digest of an arbitrary string and returns the result via
+.Fn RMD160End .
+.Pp
+For each of the
+.Fn RMD160End ,
+.Fn RMD160File ,
+and
+.Fn RMD160Data
+functions the
+.Ar buf
+parameter should either be a string of at least 41 characters in
+size or a NULL pointer.
+In the latter case, space will be dynamically allocated via
+.Xr malloc 3
+and should be freed using
+.Xr free 3
+when it is no longer needed.
+.Sh EXAMPLES
+The follow code fragment will calculate the digest for
+the string "abc" which is ``0x8eb208f7e05d987a9b044a8e98c6b087f15a0bfc''.
+.Bd -literal -offset indent
+RMD160_CTX rmd;
+u_char results[20];
+char *buf;
+int n;
+
+buf = "abc";
+n = strlen(buf);
+RMD160Init(&rmd);
+RMD160Update(&rmd, (u_char *)buf, n);
+RMD160Final(results, &rmd);
+
+/* Print the digest as one long hex value */
+printf("0x");
+for (n = 0; n < 20; n++)
+       printf("%02x", results[n]);
+putchar('\\n');
+.Ed
+.Pp
+Alternately, the helper functions could be used in the following way:
+.Bd -literal -offset indent
+RMD160_CTX rmd;
+u_char output[41];
+char *buf = "abc";
+
+printf("0x%s\en", RMD160Data(buf, strlen(buf), output));
+.Ed
+.Sh CAVEATS
+If a message digest is to be copied to a multi-byte type (ie:
+an array of five 32-bit integers) it will be necessary to
+perform byte swapping on little endian machines such as the i386, alpha,
+and vax.
+.Sh AUTHOR
+This implementation of RMD-160 was written by Antoon Bosselaers.
