in reply to xxHash Base64

If you are running a 64-bit build of perl, or one that has 64-bit integer math, then you could do the following:

use Digest::xxHash64 qw[ xxHash64 ];
use Mime::Base64;

my $data = ...; ## from wherever

my $xxH64B64 = encode_base64( pack 'Q', xxHash64( $data ) );

    Or if you're not using a 64-bit perl,

    encode_base64( pack('H*', xxhash64_hex($data, 0)) );

    Note that xxhash is not preimage-resistant, so comparing it to cryptographic hashes like MD5 and SHA1 is highly misleading.
