GenerateRandomString is a function that generates a random string of the specified length (length int) and returns it as a text (string). The string is generated using a combination of lowercase and uppercase letters. The function uses a seeded random number generator to ensure that the generated string is truly random.
Parameters:
- length (int): The length of the random string to generate.
func GenerateRandomString(length int) string {
// Define the charset for generating the random string
const charset = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ"
// Create a seeded random number generator using the current time as the seed
seededRand := rand.New(rand.NewSource(time.Now().UnixNano()))
// Create a byte slice to store the generated string
b := make([]byte, length)
// Generate the random string by selecting a random character from the charset for each index in the byte slice
for i := range b {
b[i] = charset[seededRand.Intn(len(charset))]
}
// Return the generated string
return string(b)
}
