 Digest::file - Calculate digests of files

SSYYNNOOPPSSIISS #

   # Poor mans "md5sum" command
   use Digest::file qw(digest_file_hex);
   for (@ARGV) {
       print digest_file_hex($_, "MD5"), "  $_\n";
   }

 This module provide 3 convenience functions to calculate the digest of
 files.  The following functions are provided:

 digest_file( $file, $algorithm, [$arg,...] )
     This function will calculate and return the binary digest of the
     bytes of the given file.  The function will croak if it fails to open
     or read the file.

     The $algorithm is a string like "MD2", "MD5", "SHA-1", "SHA-512".
     Additional arguments are passed to the constructor for the
     implementation of the given algorithm.

 digest_file_hex( $file, $algorithm, [$arg,...] )
     Same as ddiiggeesstt__ffiillee(()), but return the digest in hex form.

 digest_file_base64( $file, $algorithm, [$arg,...] )
     Same as ddiiggeesstt__ffiillee(()), but return the digest as a base64 encoded
     string.
