Dear Group

To get CRC32 and MD5 ... hash of a file, I could use

({FileHash[#,"CRC32"],FileHash[#,"MD5"], ...})&/@fileList

but it doesn't look smart because each file is read twice, a first time to compute CRC32 and second one for MD5, etc..

Any better way ?

A simple way to efficiently parallelize this peculiar task over a multicore cpu would be very welcomed also.

Thanks !!
