I have a bit of experience with the MD5... I use:
sub file_md5_hex
{
my ($file) = @_;
my $logger = get_logger("root.file_md5_hex");
my $output = `/usr/bin/openssl dgst -hex -md5 < $file`;
chomp $output;
$logger->debug("MD5 of $file is $output");
$output;
}
instead of:
# we do not use this because it reads the whole file into memory...AT ONCE!
#use Digest::MD5::File qw(file_md5_hex);
The latter was blowing out my memory when I md5'd 2G files. Openssl
works fine. Also, if you have any sort of hardware accelerator,
(Hifn, etc) they appear to come with new openssl libraries, so you
would get the acceleration benefits.
