HSM (Hardware Security Modules, módulos de segurança de hardware) e etokens são dispositivos de computação dedicados, resistentes e à violação, projetados para gerenciar, processar e armazenar chaves digitais com segurança. Esses dispositivos são conectados diretamente a um computador ou servidor de rede.
O Adobe Experience Manager Forms pode usar credenciais armazenadas em um HSM ou token para assinar eletronicamente ou aplicar assinaturas digitais do lado do servidor a um documento. Para usar um dispositivo HSM ou etoken com o AEM Forms:
No Microsoft Windows, somente clientes LunaSA ou EToken de 32 bits são suportados.
Por padrão, o serviço DocAssurance não está habilitado. Execute as seguintes etapas para ativar o serviço:
Pare a instância de Autor do seu ambiente do AEM Forms.
Abra o [AEM_root]arquivo \crx-quickstart\conf\sling.properties para edição.
Se você tiver usado o [AEM_root]\crx-quickstart\bin\start.bat para iniciar a instância do AEM, abra o [AEM_root]\crx-quickstart\sling.properties arquivo para edição.
Adicione ou substitua as seguintes propriedades no arquivo sling.properties:
sling.bootdelegation.sun=sun.*,com.sun.*,sun.misc.*
sling.bootdelegation.ibm=com.ibm.xml.*,com.ibm.*
sling.bootdelegation.class.com.rsa.jsafe.provider.JsafeJCE=com.rsa.*
Salve e feche o arquivo sling.properties.
Reinicie a instância do AEM.
Execute as seguintes etapas para configurar certificados:
Faça logon na instância do AEM Author como administrador.
Clique em Adobe Experience Manager na Barra de navegação global. Ir para Ferramentas > Segurança > Usuários.
Clique em name da conta de usuário. A variável Editar configurações de usuário é aberta.
Na instância do autor do AEM, os certificados residem em um KeyStore. Se você não criou um KeyStore anteriormente, clique em Criar KeyStore e defina uma nova senha para o KeyStore. Se o servidor já contiver um KeyStore, ignore esta etapa.
No Editar configurações de usuário clique em Gerenciar KeyStore.
Na caixa de diálogo Gerenciamento de KeyStore, expanda a Adicionar chave de privacidade do arquivo da chave de armazenamento e forneça um alias. O alias é usado para executar a operação Reader Extensions.
Para fazer upload do arquivo de certificado, clique em Selecionar arquivo da chave de armazenamento e carregar um .pfx
arquivo.
Adicione o Senha da chave de armazenamento,Senha da chave de privacidade, e Alias da chave de privacidade que está associado ao certificado para os respectivos campos. Clique em Enviar.
Para determinar o P Alias da chave privada de um certificado, você pode usar o comando Java keytool: keytool -list -v -keystore [keystore-file] -storetype pkcs12
No Senha da chave de armazenamento e Senha da chave de privacidade especifique a senha fornecida com o arquivo de certificado.
Para o AEM Forms no OSGi, para verificar o PDF assinado, o certificado raiz instalado no Armazenamento de confiança.
Ao mudar para o ambiente de produção, substitua suas credenciais de avaliação pelas credenciais de produção. Exclua suas credenciais antigas de extensões do Reader antes de atualizar uma credencial expirada ou de avaliações.
O alias contém todos os parâmetros exigidos por um HSM ou etoken. Execute as instruções listadas abaixo para criar um alias para cada credencial HSM ou etoken que o eSign ou Digital Signatures usa:
Abra o console AEM. O URL padrão do console AEM é https://<host>:<port>/system/console/configMgr
Abra o Serviço de configuração de credenciais HSM e especifique valores para os seguintes campos:
Ao configurar o Etoken, especifique um valor numérico para o campo Id do slot HSM. É necessário um valor numérico para que as operações de Assinaturas funcionem.
Clique em Salvar. O módulo de segurança de hardware está configurado para o AEM Forms. Agora, você pode usar o módulo de segurança de hardware com o AEM Forms para assinar ou certificar documentos.
O código de amostra a seguir usa um HSM ou token para assinar ou certificar um documento.

/**
* Digital signatures can be applied to PDF documents to provide a level of security. Digital signatures, like handwritten signatures, provide a means by which signers
* identify themselves and make statements about a document. The technology used to digitally sign documents helps to ensure that both the signer and recipients are clear
* about what was signed and confident that the document was not altered since it was signed.
*
* PDF documents are signed by means of public-key technology. A signer has two keys: a public key and a private key. The private key is stored in a user's credential that
* must be available at the time of signing. The public key is stored in the user's certificate that must be available to recipients to validate the signature. Information
* about revoked certificates is found in certificate revocation lists (CRLs) and Online Certificate Status Protocol (OCSP) responses distributed by Certificate Authorities (CAs).
* The time of signing can be obtained from a trusted source known as a Timestamping Authority.
*
* The following Java code example digitally signs a PDF document that is based on a PDF file.
* The alias that is specified for the security credential is secure, and revocation checking is performed.
* Because no CRL or OCSP server information is specified, the server information is obtained from the certificate used to
* digitally sign the PDF document
*
* PreRequisites - Digital certificate for signing the document has to be uploaded on Granite Key Store
