The company should use HMAC SHA256 as a cryptographic technique to ensure that packets received between two parties have not been tampered with and the connection remains private. HMAC stands for hash- based message authentication code, which is a method of generating a message authentication code using a cryptographic hash function and a secret key. HMAC can provide both integrity and authenticity of the packets, as well as resistance to replay attacks. SHA256 is a specific hash function that produces a 256-bit output. SHA256 is considered secure and widely used in various cryptographic applications. Verified References:
