#Latest version

#Should I use this?

Only if you need interoperability with an existing system that uses Base62. For new designs, just use (URL-safe) Base64. It's practically as URL-safe as Base62 - strip the padding if that's a problem - and there are performant implementations for almost every language.

#Usage

There are two functions, encode and decode. encode takes a byte array and returns a base62-encoded string. decode takes a base62-encoded string and returns a byte array.

(require '[clj-base62.core :as base62])

(base62/encode (.getBytes "Hello world!"))
;; "T8dgcjRGuYUueWht"

(String. (base62/decode "T8dgcjRGuYUueWht"))
;; "Hello world!"

#Caveats

It's very slow for long inputs. By long, I mean in the order of 10 kB or bigger. You'll probably want to use Base64 or Base32.

#Compatibility

The goal is to be compatible with base-x npm package.
