Protocolo-Lain

Trata-se de uma ISO (DVD) estilo aqueles cd´s geek que vinha em revistas na década de 90, que sempre achei legal. :3 É mais uma expressão artística e nostálgica do que ensinamentos revolucionários. Até porque, Hackerismo é um Estilo de Vida, não se ensina isto. Mas vai ser legal pra quem esta começando. E acredito que consegui ir além do óbvio, sendo um material inicial, porém livre de redundância. Coloquei elementos "que você só encontra aqui", ou seja, tive preocupação em incluir coisas que vão além da parte técnica. Tentei criar um material tendenciosamente hacktivista, libertário, criptoanarquista. Mas acho que é prepotência minha. xD Download: https://www.youtube.com/redirect?q=https%3A%2F%2Fmega.nz%2F%23F%21isskiYrA%21E3iKrYs9iigMuPi3pibN1g&v=JquoPTFRxqk&redir_token=juzi5goTekcKvzaX7tImFexUZc98MTU4MTAwODkxNkAxNTgwOTIyNTE2&event=video_description

Delphi Cross-Platform Application Help

On the surface, Ziphelp is basically HTML in a compressed zip archive, hence the name. Pack any folder with HTML files into a zip archive and you are good to go. But Ziphelp is more than that, it is a protocol based on the standard sitemap protocol, designed to give a help viewer (here: the Delphi implementation) extended information about the content of the help system. That is help context numbers, help keywords, associative keywords, page titles. This information is missing in a standard sitemap.xml. Ziphelp extends the sitemap protocol and enables direct communication of an app with the help system. The Ziphelp protocol is not just for zip archives. It works inside an archive, with uncompressed folders or with HTML content loaded directly from a website. A Delphi desktop app may be deployed with local application help, uncompressed, zipped or embedded. A mobile or web application might not ship with local HTML content, but refer to an online version instead.

OAuth2Client

An RFC 6749 OAuth2 Client implemented as a Lazarus Package. The client is intended to be fully featured and supports the following grant types: Authorization Code Grant Implicit Grant Resource Owner Password Credentials Grant Client Credentials Grant. Attention has also been paid to extensibility. The client also provides: A means of implementing an Extension Grant, including new grant types. Support for new token types Support for New Endpoint Parameters, and Support for additional error codes. This OAuth2 Client uses an external User Agent - the System Web Browser - and incorporates in internal http server for handling redirect responses from an Authorization Server. The package uses the Indy Component library for both an http/https client and an http server. When the https protocol is used the OpenSSL library must also be installed and available for use. Multithreading support is required for Authorization Code and Implicit Grants. The package is written in Object Pascal and is made available under the Lesser GPL. The package requires the Indy package for http/https protocol support. It has been configured for use with the MWA Software IndySecOpenSSL package and the Indy Component Library. A separate branch (Indy106Compat) is also available. This will work with the Indy Component library on its own. However, you will be limited to using the unsupported OpenSSL 1.0.2 library (current is OpenSSL 3.x) and TLS 1.2. For installation instructions please refer to the User Guide.

TML Messaging Suite

Establishing asynchronous, multithreaded, bidirectional communication without blocking messages can be time consuming and error prone. Using libTML allows you to implement asynchronous message exchange on top of the IETF standard protocol BEEP (Blocks Extensible Exchange Protocol) without the need to fiddle around with the basics of message processing. All your work can be put into the features of the application instead of taming a TCP/IP socket.

IndySecOpenSSL

This repo provides the IndySecOpenSSL package for both Delphi and Lazarus/fpc. This package provides a new (optional) OpenSSL package separate from Indy's "protocols" package and adds support for OpenSSL 3.0 and later. It may be used as an add-on the Indy 10.6 or the forthcoming Indy 10.7 releases. The IndySecOpenSSL package's purpose is to provide Indy users with an upgrade path to the use of current OpenSSL (3.x) libraries with the minimum of change. This includes users that use the existing version of Indy bundled with Delphi and the version provided with the Lazarus Online Package Manager. For more information on the installation and use of the package please read the comprehensive User Guide provided in the docs subdirectory. New users should pay particular attention to the installation instructions and guidance on installation of the OpenSSL shared libraries (DLLs) included in the User Guide.
