+.Sh DESCRIPTION
+The
+.Li SHA512_
+functions calculate a 512-bit cryptographic checksum (digest)
+for any number of input bytes.
+A cryptographic checksum is a one-way
+hash function; that is, it is computationally impractical to find
+the input corresponding to a particular output.
+This net result is
+a
+.Dq fingerprint
+of the input-data, which does not disclose the actual input.
+.Pp
+The
+.Fn SHA512_Init ,
+.Fn SHA512_Update ,
+and
+.Fn SHA512_Final
+functions are the core functions.
+Allocate an
+.Vt SHA512_CTX ,
+initialize it with
+.Fn SHA512_Init ,
+run over the data with
+.Fn SHA512_Update ,
+and finally extract the result using
+.Fn SHA512_Final .
+.Pp
+.Fn SHA512_End
+is a wrapper for
+.Fn SHA512_Final
+which converts the return value to a 65-character
+(including the terminating '\e0')
+.Tn ASCII
+string which represents the 512 bits in hexadecimal.
+.Pp
+.Fn SHA512_File
+calculates the digest of a file, and uses
+.Fn SHA512_End
+to return the result.
+If the file cannot be opened, a null pointer is returned.
+.Fn SHA512_FileChunk
+is similar to
+.Fn SHA512_File ,
+but it only calculates the digest over a byte-range of the file specified,
+starting at
+.Fa offset
+and spanning
+.Fa length
+bytes.
+If the
+.Fa length
+parameter is specified as 0, or more than the length of the remaining part
+of the file,
+.Fn SHA512_FileChunk
+calculates the digest from
+.Fa offset
+to the end of file.
+.Fn SHA512_Data
+calculates the digest of a chunk of data in memory, and uses
+.Fn SHA512_End
+to return the result.
+.Pp
+When using
+.Fn SHA512_End ,
+.Fn SHA512_File ,
+or
+.Fn SHA512_Data ,
+the
+.Fa buf
+argument can be a null pointer, in which case the returned string
+is allocated with
+.Xr malloc 3
+and subsequently must be explicitly deallocated using
+.Xr free 3
+after use.
+If the
+.Fa buf
+argument is non-null it must point to at least 65 characters of buffer space.
+.Sh SEE ALSO
+.Xr md2 3 ,
+.Xr md4 3 ,
+.Xr md5 3 ,
+.Xr ripemd 3 ,
+.Xr sha 3
+.Sh HISTORY
+These functions appeared in
+.Fx 4.0 .
+.Sh AUTHORS
+The core hash routines were implemented by Colin Percival based on
+the published
+.Tn FIPS 180-2
+standard.
+.Sh BUGS
+No method is known to exist which finds two files having the same hash value,
+nor to find a file with a specific hash value.
+There is on the other hand no guarantee that such a method does not exist.
