                        method used to widen replacement string if it's too long l - pad with

Uses

• Could be used to create a modded version for a game by changing dialogues and such
• Could theoretically be used to "steal" someones binary by just replacing any info (e.g. license) with the attacker's - removes the need to decompile, change and then recompile the binary
• And more
