+# Relatório do Projeto de Desenvolvimento 1
+
+## Introdução
+
+A comunicação eficaz dentro de uma organização é essencial para a eficiência do seu funcionamento. No entanto, num ambiente cada vez mais digital, garantir a segurança e autenticidade das comunicações tem-se vindo a tornar uma preocupação fundamental. Em resposta a esta necessidade, este primeiro projeto de desenvolvimento visa criar um serviço de mensagens seguro e autenticado.
+
+Para contextualizar o projeto, consideremos uma organização onde informações confidenciais são frequentemente trocadas entre membros de equipas distribuídas geograficamente. Neste cenário, é crucial que as mensagens enviadas e recebidas sejam protegidas contra acessos não autorizados e manipulação por partes externas. Além disso, garantir que a identidade do remetente e a integridade da mensagem sejam verificadas é essencial para manter a confiança e a segurança das comunicações internas.
+
+Perante estas necessidades, o projeto de desenvolvimento propõe a criação de um sistema cliente/servidor que oferece um serviço de mensagens seguro e autenticado. Através deste sistema, os membros da organização poderão trocar mensagens com garantias de autenticidade, protegendo assim a confidencialidade e integridade das comunicações.
+
+Ao longo deste relatório iremos detalhar as decisões mais importantes tomadas no desenvolvimento do projeto, bem como as medidas de segurança implementadas para garantir a confidencialidade, integridade e autenticidade das mensagens trocadas entre os utilizadores.
+
+Algumas notas sobre o projeto:
+
+- Optamos por escolher **Golang** como linguagem visando uma implementação mais eficiente, robusta e segura ao nível de concorrência. O modelo de concorrência baseado em goroutines e canais facilita a criação de programas concorrentes e sistemas distribuídos. Com uma sintaxe simples, semelhante a **C**, o **Go** promove a escrita de código legível e de alta qualidade. Além disso, o **Go** possui um ecossistema robusto de bibliotecas e ferramentas, tornando-o uma escolha adequada para o desenvolvimento de sistemas distribuídos e serviços de back-end.
+
+- Implementamos algumas funcionalidades extra, como o armazenamento dos dados no servidor numa base de dados **sqlite3**
+
+Nas secções seguintes iremos detalhar cada componente do sistema, bem como as funcionalidades implementadas.
+
+
+
+## Análise de Risco
+
+Esta análise de risco do sistema visa identificar as potenciais vulnerabilidades e ameaças que possam comprometer a segurança do sistema de mensagens. É essencial considerar os diversos fatores que podem impactar a integridade, confidencialidade e disponibilidade das mensagens trocadas entre os utilizadores.
+
+### Potenciais Vulnerabilidades

+
+### Propriedades Requiridas:
+
+1. **Autenticidade do Remetente** - O cliente deseja ter a garantia de que a mensagem recebida foi realmente enviada pelo remetente indicado.
+
+1. **Confidencialidade das Mensagens** - O cliente quer assegurar que apenas ele possui a capacidade de decifrar as mensagens que lhe foram enviadas, garantindo assim a privacidade das comunicações.
+
+1. **Servidor Malicioso** - Os clientes pretendem proteger-se contra a possibilidade de o servidor agir de forma maliciosa, garantindo que as suas interações sejam seguras e protegidas, necessitando de mecanismos que garantam a segurança das suas interações independentemente da confiabilidade do servidor, como a utilização de criptografia *end-to-end*.
+
+1. **Comunicação Segura com o Servidor** - Os clientes exigem que a comunicação com o servidor seja segura, protegida contra acesso não autorizado e intercetação por partes não autorizadas, garantindo assim a integridade e confidencialidade dos dados transmitidos.
+
+### Medidas de Mitigação:
+
+1. **Protocolo de comunicação** - Utilizar um protocolo de comunicação que garanta a confidencialidade para proteger a comunicação entre o cliente e o servidor.
+
+1. **Armazenamento Seguro de Chaves Privadas** - Adotar práticas seguras de armazenamento para proteger as chaves privadas dos utilizadores contra acesso não autorizado, como utilizar *passphrases* para proteger o acesso à *key store*.
+
+1. **Fortalecimento da Autenticação** - Implementar métodos robustos de autenticação, como certificados digitais, para garantir a identidade dos utilizadores e proteger contra acesso não autorizado.
+
+1. **Validação de Dados** - Implementar controles de validação de dados para garantir a integridade das mensagens e prevenir a manipulação de dados por partes não autorizadas, como, por exemplo, assinar "hashes" das mensagens enviadas.
+
+1. **Atualizações de *Software*** - Manter o *software* utilizado atualizado para mitigar o risco de exploração de vulnerabilidades conhecidas e garantir a segurança do sistema.
+
+Esta breve análise de risco destaca a importância de identificar e mitigar potenciais vulnerabilidades e ameaças para garantir a segurança do sistema desenvolvido. A implementação de medidas de segurança adequadas é essencial para proteger os dados e garantir o funcionamento seguro.
+
+
+## Decisões de Arquitetura e Implementação
+
+Tendo em consideração as vulnerabilidades e ameaças identificadas na análise de risco, foram tomadas várias decisões de design e implementação para garantir a segurança e autenticidade do sistema de mensagens. As decisões tomadas visam proteger a confidencialidade, integridade e autenticidade das mensagens trocadas entre os utilizadores, bem como garantir a segurança da comunicação entre o cliente e o servidor.
+
+1. **TLS (Transport Layer Security)**
+
+   - Cada conexão entre cliente e servidor é protegida pelo protocolo TLS, garantindo que a comunicação seja segura e privada.
+   - Cliente e servidor trocam certificados para autenticar as suas identidades.
+   - Ambos verificam se o certificado foi emitido pela Autoridade de Certificação (CA) central.
+   - O cliente verifica se comunica com o servidor legítimo.
+
+1. **End-to-End Encryption (E2EE)**
+
+   - Ao enviar uma mensagem, o cliente assina a *hash* do texto simples com a sua chave privada.
+   - A assinatura é anexada ao texto limpo e esse conjunto é cifrado com uma chave de sessão gerada aleatoriamente.
+   - A chave de sessão é cifrada com a chave pública do destinatário, Isso garante que apenas o destinatário possa decifrar a mensagem.
+
+1. **Visualização da Lista de Mensagens Não Lidas**
+
+   - Quando um cliente solicita a sua lista de mensagens não lidas, apenas o assunto é enviado, não o conteúdo cifrado.
+   - O cliente deve decifrar o assunto para visualizá-lo.
+
+1. **Visualização de Mensagens**
+
+   - Quando um cliente solicita uma mensagem, é enviado o conteúdo todo da mensagem.
+   - O cliente deve decifrar o assunto e o corpo da mensagem para visualizá-los.
+
+1. **Troca de Chaves Públicas**
+
+   - Quando um cliente precisa da chave pública de outro cliente, solicita o certificado desse cliente ao servidor.
+   - Verifica-se se o certificado foi emitido pela CA central e se pertence ao cliente desejado.
+
+1. **Verificação de Inputs**
+
+   - Tanto cliente quanto servidor realizam verificações básicas nos *inputs* para garantir a sua integridade.
+   - Ambos desconfiam um do outro e verificam cuidadosamente todos os *inputs*.
+
+1. **Confiança na CA Central**
+
+   - A única confiança absoluta neste sistema é depositada na Autoridade de Certificação central, responsável por emitir os certificados.
+
+
+## Certificates and Keys
+
+Para gerar os certificados e chaves necessárias para a comunicação segura entre o cliente e o servidor, foram seguidos os seguintes passos utilizando a ferramenta **OpenSSL**. Estes passos incluem a geração de chaves privadas, certificados e *keystores* para o servidor e clientes, bem como a assinatura dos certificados pela CA central.
+
+
+1. **Gerar *CA key* e o *certificate***
+
+```bash
+openssl genrsa -aes256 -out CA/CA.key 4096
+openssl req -x509 -new -nodes -key CA/CA.key -sha256 -days 18250 -out CA/CA.pem -subj "/2.5.4.3=CA"
+```
+A *passhphrase* da CA é 1234
+
+2. **Gerar a *server key* e *CSR***
+
+```bash
+openssl genrsa -out server/server.key 4096
+openssl req -new -key server/server.key -out server/server.csr -subj "/2.5.4.11=MSG SERVICE/2.5.4.65=SERVER"
+```
+
+3. **Assinar o *CSR* do *server* com a *CA***
+
+```bash
+openssl x509 -req -in server/server.csr -CA CA/CA.pem -CAkey CA/CA.key -CAcreateserial -out server/server.crt -days 1825 -sha256
+```
+
+4. **Gerar o *keystore* do *server***
+
+```bash
+openssl pkcs12 -export -out server/server.p12 -inkey server/server.key -in server/server.crt -certfile CA/CA.pem -name "ServerKeyStore"
+```
+A passphrase usada para o *keystore* é server
+
+5. **Gerar as chaves e *CSR* de cada *client***
+
+```bash
+openssl genrsa -out client{NUM}/client{NUM}.key 4096
+openssl req -new -key client{NUM}/client{NUM}.key -out client{NUM}/client{NUM}.csr -subj "/2.5.4.11=MSG SERVICE/2.5.4.65=CL{NUM}/2.5.4.3=Client {NUM}"
+```
+
+6. **Assinar os *CSR* dos clientes com a *CA***
+
+```bash
+openssl x509 -req -in client/client.csr -CA CA/CA.pem -CAkey CA/CA.key -CAcreateserial -out client/client.crt -days 1825 -sha256
+```
+7. **Gerar o *keystore* do *client***
+
+```bash
+openssl pkcs12 -export -out client{NUM}/client{NUM}.p12 -inkey client{NUM}/client{NUM}.key -in client{NUM}/client{NUM}.crt -certfile CA/CA.pem -name "Client{NUM}KeyStore"
+```
+A passphrase usada para o *keystore* é client{NUM}
+
+Neste processo, foram geradas as chaves privadas, certificados e *keystores* necessários para estabelecer uma comunicação segura entre os clientes e o servidor. Os certificados foram assinados pela Autoridade de Certificação (CA) central, garantindo a autenticidade e integridade dos certificados emitidos. Os *keystores* contêm tanto o certificado quanto a chave privada do cliente ou servidor, protegidos por *passhprase* para garantir a confidencialidade e segurança das chaves privadas. Este processo de geração de certificados e *keystores* é essencial para estabelecer uma comunicação segura e autenticada entre os componentes do sistema.
+
+### Certificados
+- **Autenticidade**: Os certificados são assinados digitalmente pela Autoridade de Certificação (CA) central, garantindo sua autenticidade. Isso significa que os clientes podem verificar se o certificado foi emitido por uma entidade confiável.
+- **Criptografia**: Os certificados contêm a chave pública do cliente ou do servidor, que é usada para estabelecer uma comunicação segura por meio de criptografia assimétrica. Isso permite que as mensagens sejam cifradas pelo remetente e decifradas apenas pelo destinatário.
+- **Verificação**: Antes de confiar num certificado, os clientes verificam sua validade, incluindo a data de expiração e a correspondência com a entidade emissora. Isso ajuda a evitar a utilização de certificados inválidos ou falsificados.
+
+### *Keystores*
+- **Armazenamento Seguro**: Os *keystores* são arquivos protegidos por *passphrase* que contêm tanto o certificado quanto a chave privada do cliente ou servidor. Essas informações sensíveis são protegidas por meio de criptografia, garantindo que apenas o proprietário autorizado possa acessá-las.
+- **Proteção da Chave Privada**: A *passphrase* do *keystore* protege a chave privada contra acesso não autorizado. Isso é crucial, pois a chave privada é usada para decifrar as mensagens recebidas e assinar as mensagens enviadas, garantindo a autenticidade e integridade da comunicação.
+- **Confidencialidade**: Como os *keystores* são protegidos por *passphrase*, mesmo que alguém obtenha acesso ao arquivo, não poderá extrair a chave privada sem a *passphrase* correta. Isso ajuda a manter a confidencialidade das chaves privadas dos usuários.
+
+
+## Criptografia
+
+É importante destacar que, para garantir a segurança e integridade das mensagens, implementamos um protocolo de comunicação seguro. Este protocolo utiliza tanto criptografia simétrica quanto assimétrica. As mensagens são cifradas com uma chave de sessão gerada aleatoriamente, que, é cifrada com a chave pública do destinatário para garantir a confidencialidade. As mensagens são também assinadas com a chave privada do emissor para autenticidade. Dessa forma, asseguramos que as mensagens sejam protegidas contra acessos não autorizados e que a sua origem possa ser verificada.

+
+
+### Networking
+
+O canal de comunicação estabelecido entre o cliente e o servidor nesta implementação garante uma troca de dados segura e criptografada utilizando o protocolo TLS (Transport Layer Security). Ambos, cliente e servidor, empregam configurações TLS para cifrar os dados durante a transmissão, assegurando confidencialidade e integridade. Durante o handshake TLS, o servidor valida o certificado do cliente para verificar sua autenticidade, prevenindo acessos não autorizados. Este mecanismo robusto de segurança protege o canal de comunicação contra escutas, adulterações e ataques do tipo "man in the middle", garantindo uma troca de informações segura e confiável entre o cliente e o servidor.
+
+### Protocolo de Comunicação
+
+O package **protocol.go** define um conjunto de estruturas e funções que representam os diferentes tipos de pacotes que podem ser transmitidos entre o cliente e o servidor. Cada tipo de pacote é representado por uma constante PacketType, que indica a natureza da informação contida no pacote através de uma **flag**.
+
+As estruturas de dados definidas, como `GetUserCert`, `GetUnreadMsgsInfo`, `GetMsg`, `SendMsg`, `AnswerGetUserCert`, `AnswerGetUnreadMsgsInfo` e `AnswerGetMsg`, descrevem os formatos específicos de cada tipo de pacote a ser enviado e recebido. Cada estrutura contém os campos necessários para armazenar e representar os dados associados a cada tipo de pacote.
+
+Além disso, foram implementadas funções auxiliares para criar instâncias de cada tipo de pacote, como `NewGetUserCert`, `NewGetUnreadMsgsInfo`, `NewGetMsg`, `NewSendMsg`, `NewAnswerGetUserCert`, `NewAnswerGetUnreadMsgsInfo` e `NewAnswerGetMsg`. Estas funções facilitam a criação de pacotes com os dados necessários de forma estruturada.
+
+Para facilitar a serialização e desserialização dos pacotes em formato JSON, foram implementadas funções `Unmarshal` específicas para cada tipo de pacote. Estas funções convertem os dados do pacote entre o formato JSON e as estruturas de dados correspondentes, permitindo a comunicação eficiente entre o cliente e o servidor.
+
+Este package serve como uma camada de abstração que facilita a comunicação entre os componentes cliente e servidor, garantindo que os dados sejam transmitidos de forma estruturada e *standardized*, facilitando o desenvolvimento, manutenção e expansão do sistema de comunicação.
+
+### Sqlite3 Database
+
+Como mencionado anteriormente neste relatório, uma das funcionalidades adicionais implementadas foi o armazenamento dos dados do servidor numa base de dados persistente. Neste projeto, optamos por utilizar o **SQLite3**. Este é utilizado para armazenar as mensagens enviadas e recebidas pelos utilizadores, além dos certificados digitais dos clientes. A escolha de uma base de dados permite a persistência segura e eficiente dos dados, assegurando que as mensagens e certificados sejam armazenados de maneira duradoura e acessível.
+
+Em relação à segurança contra ataques como *SQL Injection*, é crucial adotar medidas para mitigar esse tipo de ameaça. A utilização de *prepared statements* é uma prática essencial para prevenir ataques deste tipo. Com *prepared statements*, os valores dos parâmetros são tratados como dados e não como parte do comando SQL, o que reduz significativamente o risco de injeção de código malicioso. Essa abordagem fortalece a segurança do sistema, garantindo a integridade e confiabilidade das operações da base de dados.
+
+
+
+### Verificações e Testes de Segurança
+
+Para realizar testes e verificações de segurança implementamos também um *Fake Client, Server e CA*, que permitem testar a segurança do sistema em diferentes cenários, como tentativas de intercetação de dados, manipulação de mensagens, autenticação fraca e outros tipos de ataques.
