There are three main ways to generate encrypted signatures in PHP. 1. Use hash_hmac for HMAC signatures, and generate signatures through key and hash algorithms (such as sha256), which is suitable for API interface requests and callback verification; 2. Use openssl_sign to implement RSA signatures, using private key signatures and public key verification, which are suitable for high-security scenarios such as payment callbacks; 3. Signing after splicing parameters, which is often used in API interfaces. The parameters need to be sorted according to rules and added with keys to generate signatures to prevent replay attacks. In addition, the signature field is recommended to be unified into sign or signature and transmitted over HTTPS to ensure security.
