This looks like a classic example of (also known as "nearby key" encoding), where each letter is shifted to an adjacent key on a standard QWERTY keyboard.

Decode each cipher letter by moving one key on QWERTY: n ← h (yes: h's left is g? No — h left is g, so n left is? Let's do systematically: Cipher n: on QWERTY, left of n is b, not h. So that fails. So it's right shift — cipher = plain shifted right one key. Then decode by shifting cipher left. Let's do systematically: Cipher n: on QWERTY, left

So the decoding is: each letter in the gibberish is replaced by the key physically to its on a standard US QWERTY keyboard (i.e., ciphertext = plaintext shifted one key to the right). To decode, shift each cipher letter one key to the left.
