How to hash a string using a custom hash function in Go?

To hash a string using a custom hash function in Go, you can follow these steps:

Create a custom hash function that takes a string argument and returns an integer (hash value). For example, you can create a simple hash function that sums up the ASCII values of the characters in the string:

func customHash(str string) int {
    hash := 0
    
    for _, character := range str {
        hash += int(character)
    }
    
    return hash
}

Call the custom hash function with the string you want to hash. For example:

stringToHash := "Hello, World!"
hashValue := customHash(stringToHash)

The hashValue variable will store the hash value of the given string.

Note that this is a simple and straightforward hash function implementation for demonstration purposes. In practice, you may want to use more complex and secure hash functions like SHA256 or bcrypt for stronger security.
