👉 In cryptography and computer science, a "backchain" is an algorithm or function that generates a random number in a cryptographic context. It's typically used to generate pseudo-random numbers for use in secure hashing algorithms like SHA-256. This function is often called "randomize" because it can be used to generate unpredictable outputs. A common example of a backchain is the `rand()` function in many programming languages that is used by cryptographic libraries like OpenSSL and GPG to generate pseudo-random
