[Question] What is the license of PRVHASH algorithm (not the code in this repository)? #7

Chacha20 is a stream cipher with a public domain license, but many implementations of it in Github have their own licenses such as MIT or GPL.

There is also this statement in the repository:

"PRVHASH "computer program" authorship and copyright were registered at the [Russian Patent Office](https://rospatent.gov.ru/en), under reg.numbers 2020661136, 2020666287, 2021615385, 2021668070, 2022612987 (searchable via [fips.ru](https://new.fips.ru/en/)). Please note that these are not "invention patents"; the registrations assure you that the author has the required rights to grant the software license to you."

I'm little confused about the PRVHASH license. What is the license of PRVHASH itself (not the code in this repository)? It it MIT too?

@avaneev I mailed you about this question but I deleted a list of messages by accident and maybe the reply was gone.

Thanks.

All available prvhash code is under MIT license.

I'll also add that the "public domain" licenses may not be enforcable in all countries, until author's death. MIT license is a better option for such licensing.
