Summary
- The sensitive data sent between services could be protected further by using an additional layer of encryption, according to this confidential message exchange between services.
- If data is intercepted during transit or decrypted at the endpoints, this additional protection could ensure that the data is secure and tamper-proof.
- To achieve confidentiality through encryption, digital signatures will ensure integrity and authentication.
- Cryptographic keys will be used for symmetric and asymmetric encryption.
- You can view the full code solution on GitHub.
- This additional protective measure is recommended for financial transactions, healthcare data exchanges, and the sharing of confidential business information.
Ensuring confidentiality, integrity, and authentication while performing RESTful API interactions can be achieved through encryption and digital signing of messages. In situations where sensitive information is exchanged, this provides an extra level of security for the communication. For the solution described in the article, GitHub provides a repository containing the full code. In order to protect the message content from unauthorized access and confirm the authenticity and integrity of the message, encryption, and signing mechanisms are applied using cryptographic keys. The usage of symmetric and asymmetric encryption offers a balance between performance and security.
