It is a generalized version of Amazon's AWS Signature Version 4 algorithm. The goal was implementing a protocol where every request is validated, and impossible to modify without knowing the secret.\n\nEscher is great for creating secure REST API servers, both the **request signing**, and **validation** are implemented. The protocol also provides a solution for **presigning URLs** with expiration.\n\nThe status is **work in progress**, however we have implementations in 7 programming languages.\n\nYour help will be *much welcomed*, we are especially interested in **code reviews**, **library implementations in different languages**, **writing the documentation** and **promotion**.\n\nFeel free to join and discuss at Escher's [general mailing list](https://groups.google.com/forum/#!forum/escherauth).\n\n**Implementations**:\n * **PHP** - source code: [EscherPHP](https://github.com/emartech/escher-php) - composer package: [emartech/escher](https://packagist.org/packages/emartech/escher)\n * **Ruby** - source code: [EscherRuby](https://github.com/emartech/escher-ruby) - gem: [escher](https://rubygems.org/gems/escher)\n * **NodeJS** - source code: [EscherJS](https://github.com/emartech/escher-js) - npm package: [escher-auth](https://www.npmjs.org/package/escher-auth)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Femartech%2Fescher","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Femartech%2Fescher","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Femartech%2Fescher/lists"}
