AWS Encryption SDK exemplos de formato de mensagem

As informações nesta página são uma referência para criar sua própria biblioteca de criptografia compatível com o AWS Encryption SDK. Se você não estiver criando sua própria biblioteca de criptografia compatível, provavelmente não precisará dessas informações. Para usar o AWS Encryption SDK em uma das linguagens de programação suportadas, consulteLinguagens de programação. Para a especificação que define os elementos de uma AWS Encryption SDK implementação adequada, consulte a AWS Encryption SDK Especificação em GitHub.

Os tópicos a seguir mostram exemplos do formato da AWS Encryption SDK mensagem. Cada exemplo mostra os bytes brutos, em notação hexadecimal, seguidos por uma descrição do que os bytes representam.

Dados emoldurados (formato de mensagem versão 1)

O exemplo a seguir mostra o formato da mensagem para dados com moldura na vesão 1 do formato de mansagem.

Dados não emoldurados (formato de mensagem versão 1)

O exemplo a seguir mostra o formato da mensagem para dados sem moldura.

nota

Sempre que possível, use dados com moldura. O AWS Encryption SDK suporta dados não emoldurados somente para uso antigo. Algumas implementações de linguagem do ainda AWS Encryption SDK podem gerar texto cifrado sem moldura. Todas as implementações de linguagem compatíveis podem descriptografar texto cifrado e não emoldurado.
