BBDIGEST(1)

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, SHA1 or RIPEMD160 message digest algorithm. 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
