  • Ticket #1164 – Description

    v23 v24  
    1010And to make it so that caps of that new type get encrypted/decrypted with XSalsa20+AES-128 instead of with AES-256. For the first release of Tahoe-LAFS which includes that functionality, it will still by default create new caps using the old encryption of only AES-256. It is important that people feel free to upgrade to new versions of Tahoe-LAFS without having to take any steps to ensure backward-compatibility, and that means that the new version of Tahoe-LAFS ''must not'', by default, produce caps that older versions of Tahoe-LAFS (such as v1.8.0) can't read.
