base62 is a compact and fast implementation of Base62 encoding/decoding algorithm,
which is inspired by the java implementation by glowfall.
As this package was written, I did not find good base62 implementation on github. The following packages can only encode/decode integers:
- https://github.com/gravityblast/go-base62/
- https://github.com/kare/base62
- https://github.com/catinello/base62
While this package encodes/decodes bytes of arbitrary length, as well as integers.
This Base62 implementation is much faster than big.Int based implementation,
and is not much slower than typical Base64 implementations. See the following
benchmark results.
