In this article, we will see how to write a Go program that generates random strings with different character sets using a function called randomHash
.
First, we need to import the following packages
- The
fmt
package is used for formatted I/O operations
math/rand
is used for generating random numbersstrings
is used for string manipulation-
time
is used for seeding the random number generator.
Now, we have to create a character pool with the different character sets such as alphanumeric, alphabetic, lowercase alphabetic with special characters, lowercase alphanumeric, hexadecimal, numeric, and non-zero numeric values.
To ensure the generated random strings are unpredictable, we seed the random number generator using the current time.
After that, We create a byte slice called buf
with the specified length and fill it with random characters from the selected pool.
Here is the detailed example program of how to generate a random string using golang:
