+### Md5
+
+<details><summary>Expand</summary>
+<p>
+
+The `md5()` function takes a string of any length and returns a fixed hash value. For example, when `md5()` is applied to the string `Alice & Bob`, it produces the hash `def42e1abd2462df1f9f0a4b3d488221`. This function is particularly useful for creating unique yet shorter identifiers, making it a good option when SHA-256’s 64-character output is too long for Kubernetes resource constraints.

+
+The `sha1()` function takes a string of any length and returns a fixed hash value. For example, when `sha1()` is applied to the string `Alice & Bob`, it gives the output as its SHA1 hash, `e3ec484930685a61b0f824cd684a68699d2b98c1`. This function is particularly useful for creating unique yet shorter identifiers, making it a good option when SHA-256’s 64-character output is too long for Kubernetes resource constraints.
