Description

This shell script generates WordPress salt values on its own.

Unlike most other scripts, this script does not fetch values from https://api.wordpress.org/secret-key/1.1/salt/. Instead, it uses a built-in function that generates the salt values identical to the WordPress website. To do this, the original WordPress wp_generate_password() function has been converted from PHP to shell.

The following options are available:

  • --no-extra-special-chars Exclude extra special characters, e.g. -_ []{}<>~`+=,.;:/?|
  • --no-special-chars Exclude special characters, e.g. !@#$%^&*()
  • --length=num (default: 64) Length of the salt values
  • --help

Example Usage & Output

Example 1

Generate salt values identical to https://api.wordpress.org/secret-key/1.1/salt/

./wp-generate-salt.sh

Example 2

Generate salt values consisting only of lowercase/uppercase letters and numbers

./wp-generate-salt.sh --no-extra-special-chars --no-special-chars
