Hi,

I'm the designer of Parchive Version 2.0 (.par2 files).  I'm looking into doing Parchive Version 3.0.  Version 2.0 used MD5 hashes to identify files and confirm their correct arrival.  Given that MD5 is "severely compromised", I'm exploring using other hashes. 

The fastest cryptographic hashes are Blake3 and KangarooTwelve.  Parchive doesn't rely on the security properties - we could reuse MD5 or even switch to a non-cryptographic hash - but it is nice.  We case more that an algorithm is widely available in good libraries in multiple languages. 

Are there plans / requests for either of Blake3 or KangarooTwelve to be added to crypto++?  

Thanks,

Mike

Regardless, for *non-cryptographic* purposes you should consider only how well a given hash performs. MD4 would be fine too.

Having said that, Blake3 probably would be supported (eventually), only question is when.
