+# The Parity Public License 7.0.0-pre.3
+
+Contributor: Kat Marchán <kzm@zkat.tech>
+
+Source Code: https://github.com/zkat/ssri-rs
+
+## Purpose
+
+This license lets you use and share this software for free, as long as you contribute software you develop, operate, or analyze with it.
+
+## Acceptance
+
+In order to receive this license, you have to agree to its rules. Those rules are both obligations under your agreement and conditions to your license. Don't do anything with this software that triggers a rule you can't or won't follow.
+
+## Notices
+
+Make sure everyone who gets a copy of any part of this software from you, with or without changes, also gets the text of this license and the contributor and source code lines above.
+
+## Copyleft
+
+[Contribute](#contribute) software you develop, operate, or analyze operate with this software, including changes or additions to this software. When in doubt, [contribute](#contribute).
+
+## Prototypes
+
+You don't have to [contribute](#contribute) any change, addition, or other software that meets all these criteria:
+
+1.  You don't use it for more than thirty days.
+
+2.  You don't share it outside the team developing it, other than for non-production user testing.
+
+3.  You don't develop, operate, or analyze software with it for anyone outside the team developing it.
+
+## Contribute
+
+When this license requires you to [contribute](#contribute) software:
+
+1.  Publish all source code for the software, in the preferred form for making changes, through a freely accessible distribution system widely used for similar source code, so the contributor and others can find and copy it.
+
+2.  Make sure each part of the source code is available to the public under a license that gives as much or more permission as this one, such as [Blue Oak Model 1.0.0](https://blueoakcouncil.org/license/1.0.0), [Apache 2.0](https://www.apache.org/licenses/LICENSE-2.0.html), [MIT](https://spdx.org/licenses/MIT.html), or [two-clause BSD](https://spdx.org/licenses/BSD-2-Clause.html).
+
+3.  Take these steps within thirty days.
+
+4.  Note that this license does _not_ allow you to change the license terms for this software.
+
+## Excuse
+
+You are excused for unknowingly breaking [Copyleft](#copyleft) if you [contribute](#contribute) as required, or stop doing anything requiring this license, within thirty days of learning you broke the rule. You are excused for unknowingly breaking [Notices](#notices) if you take all practical steps to comply within thirty days of learning you broke the rule.
+
+## Defense
+
+Don't make any legal claim against anyone accusing this software, with or without changes, alone or with other technology, of infringing any patent.
+
+## Copyright
+
+The contributor licenses you to do everything with this software that would otherwise infringe their copyright in it.
+
+## Patent
+
+The contributor licenses you to do everything with this software that would otherwise infringe any patents they can license or become able to license.
+
+## Reliability
+
+The contributor can't revoke this license.
+
+## No Liability
+
+**_As far as the law allows, this software comes as is, without any warranty or condition, and the contributor won't be liable to anyone for any damages related to this software or this license, under any kind of legal claim._**

+# Patron License
+
+Payment Platforms:
+
+- <https://github.com/sponsors/zkat>
+
+Participating Contributors:
+
+- Kat Marchán
+
+## Purpose
+
+This license gives everyone patronizing contributors to this software permission to ignore any noncommercial or copyleft rules of its free public license, while continuing to protect contributors from liability.
+
+## Acceptance
+
+In order to agree to these terms and receive a license, you must qualify under [Patrons](#patrons). The rules of these terms are both obligations under your agreement and conditions to your license. That agreement and your license continue only while you qualify as a patron. You must not do anything with this software that triggers a rule that you cannot or will not follow.
+
+## Patrons
+
+To accept these terms, you must be enrolled to make regular payments through any of the payment platforms pages listed above, in amounts qualifying you for a tier that includes a "patron license" or otherwise identifies a license under these terms as a reward.
+
+## Scope
+
+Except under [Seat](#seat) and [Applications](#applications), you may not sublicense or transfer any agreement or license under these terms to anyone else.
+
+## Seat
+
+If a legal entity, rather than an individual, accepts these terms, the entity may sublicense one individual employee or independent contractor at any given time. If the employee or contractor breaks any rule of these terms, the entity will stand directly responsible.
+
+## Applications
+
+If you combine this software with other software in a larger application, you may sublicense this software as part of your larger application, and allow further sublicensing in turn, under these rules:
+
+1. Your larger application must have significant additional content or functionality beyond that of this software, and end users must license your larger application primarily for that added content or functionality.
+
+2. You may not sublicense anyone to break any rule of the public license for this software for any changes of their own or any software besides your larger application.
+
+3. You may build, and sublicense for, as many larger applications as you like.
+
+## Copyright
+
+Each contributor licenses you to do everything with this software that would otherwise infringe that contributor's copyright in it.
+
+## Notices
+
+You must ensure that everyone who gets a copy of any part of this software from you, with or without changes, also gets the texts of both this license and the free public license for this software.
+
+## Excuse
+
+If anyone notifies you in writing that you have not complied with [Notices](#notices), you can keep your agreement and your license by taking all practical steps to comply within 30 days after the notice. If you do not do so, your agreement under these terms ends immediately, and your license ends with it.
+
+## Patent
+
+Each contributor licenses you to do everything with this software that would otherwise infringe any patent claims they can license or become able to license.
+
+## Reliability
+
+No contributor can revoke this license, but your license may end if you break any rule of these terms.
+
+## No Liability
+
+**_As far as the law allows, this software comes as is, without any warranty or condition, and no contributor will be liable to anyone for any damages related to this software or this license, under any kind of legal claim._**
