I remember that wagon, at least 1.0-beta-4, strips everything after " *" in the signature file including, so it should already be implemented on the reading side. Wagon team - please correct me if I am wrong - I did not check out the wagon source.

So we'll have to add it to the writing side of wagon code and I'll add this to Mercury.

Question is - should verification fail if file name does not match? In the light of the latest event - CCC generating MD5 collisions - it's kind of pointless.

Overall - MD5 and SHA1 can only check for non-intentional data modifications, they don't address non-repudiation problems. And when was it last time you data was crippled during transfer? It does not happen any more..

That is why we should switch to PGP signatures as soon as possible - Mercury and Mercury Ant provide full support for that :)

Thanks,
Oleg

Not to mention, that there is already a lot of files generated by md5sum and
sha1sum apps on central:

http://repo2.maven.org/maven2/log4j/log4j/maven-metadata.xml.sha1

But in the above cases, the path is obviously misleading.

 I'm -1 to making a new format
Just to make sure we all have the same understanding: The proposed format
is not "new" as in "yet another checksum format". It's an already existing
format used by the md5sum tool (compare the format attribute of Ant's
checksum task [0]).
