Which cryptographic extension provides generation and verification of digital signatures?
- The OpenSSL extension provides generation and verification of digital signatures in PHP.
- The Mcrypt extension provides generation and verification of digital signatures in PHP.
- The Hash extension provides generation and verification of digital signatures in PHP.
- The Crypt extension provides generation and verification of digital signatures in PHP.
The OpenSSL extension provides generation and verification of digital signatures in PHP. It offers a wide range of cryptographic functions, including the ability to generate and verify digital signatures. Digital signatures are widely used for data integrity and authentication in secure communication. The OpenSSL extension provides functions such as openssl_sign() and openssl_verify() that allow you to generate and verify digital signatures using different algorithms, such as RSA or DSA. It's important to note that the Mcrypt extension is primarily used for encryption and decryption, and the Hash extension is used for hashing algorithms. The Crypt extension does not provide digital signature functionality.
