Base62 Encoding: A single prevalent technique is to work with Base62 encoding (which makes use of sixty two figures: 0-9, A-Z, plus a-z) on an integer ID. The ID corresponds into the entry from the databases. This method ensures that the quick URL is as limited as is possible.
Random String Technology: Another method is always to make a random string of a fixed length (e.g., six characters) and Test if it’s already in use in the databases. Otherwise, it’s assigned towards the extensive URL.
