Download links for sha256/sha512 checksums

Hi to all,

updated the download page having now sha256/sha512 links...

Most important:

https://maven.apache.org/download.cgi

So you would say having only sha1, sha256 ?

to me, going to sha1 only *for fingerprints* is the right move currently

going to sha256 would make people think that a strong fingerprint means a 
stronger security: this is wrong
If you want security, check signatures (ie. .asc files, with corresponding 
public keys) that are real security (done with strong fingerprints built 
inside)

but fingerprints only are just checksums against download issues: technically, 
we could stay with md5 or even weaker (good old crc?), IMHO. That's just to 
avoid bad md5 reputation that we need to avoid it now: md5 for signature is 
bad, but md5 for fingerprint could still be sufficient.

Regards,

Hervé

I would definitively keep SHA-1 around. As for SHA2-512, isn't there any 
benefit for us ATM compared to 256?
