What type of encryption is used by HTTPS to secure communication in web services?
- Asymmetric-Key Encryption
- Hashing Algorithms
- Public-Key Infrastructure (PKI)
- Symmetric-Key Encryption
HTTPS primarily uses Asymmetric-Key Encryption. It employs a combination of public and private keys to secure communication between the client and the server. This ensures confidentiality and integrity by encrypting data in transit, providing a secure environment for web services.
How does SOAP handle data encoding for transmission?
