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
