Treat Balloon as one algorithm #5

Closed samuel-lucas6 closed 4 months ago

samuel-lucas6 commented 8 months ago

Currently, Balloon and Balloon-M are both specified, with Balloon-M recommended if doing a cryptographic library implementation. I don't like algorithms with multiple variants as it complicates things, so perhaps only Balloon-M should be specified, with Balloon treated as an internal function like what scrypt does with scryptROMix.

Balloon-M will be renamed to Balloon in the next version of the draft, and the current Balloon function will have to be renamed to something else (e.g. EME for Expand Mix Extract). This will leave one algorithm with support for parallelism.
