I am looking for a way to compute crc checksum cross platform.
cksum works on Linux, AIX, HP-UX Itanium, Solaris, is there a equivalent command of linu
cksum
It looks as if there is an unsupported tool for checksums from MS. It's light on features but appears to do what you're asking for. It was published in August of 2012. It's called "Microsoft File Checksum Integrity Verifier".
