NAME

       bbdigest - calculate message digests

SYNOPSIS

       bbdigest md5|sha1|rmd160 [filename]

DESCRIPTION

       bbdigest(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 bbtest-net(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.

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

EXAMPLE

	  $ bbdigest md5 index.html
	  md5:88b81b110a85c83db56a939caa2e2cf6

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