NAME

       xymondigest - calculate message digests

SYNOPSIS

       xymondigest md5|sha1|sha256|sha512|sha224|sha384|rmd160 [filename]

DESCRIPTION

       xymondigest(1) is a utility to calculate message digests for a file or document. It is used when defining
       HTTP- or FTP-based content checks, where xymonnet(1) checks that  a  URL  returns  a  specific  document;
       instead  of  having to compare the entire document, the comparison is done against a pre-computed message
       digest value using the MD5, RIPEMD160, SHA1 or any of  the  SHA2  (SHA-512,  SHA-256,  SHA-384,  SHA-224)
       message digest algorithms.

       The  optional  filename  parameter  is  the  input  file whose message digest should be calculated; if no
       filename is given, the data is read from standard input.

       xymondigest outputs a string containing the digest algorithm and the computed message digest. This is  in
       a format suitable for use in the hosts.cfg(5) definition of a content check.

EXAMPLE

          $ xymondigest md5 index.html
          md5:88b81b110a85c83db56a939caa2e2cf6

          $ curl -s http://www.foo.com/ | xymondigest sha1
          sha1:e5c69784cb971680e2c7380138e04021a20a45a2
