Base32 encoding for 64-bit values.

Crockford Base32 Encoding is most commonly used to make numeric identifiers slightly more user-resistant. Similar to Hashids, the purpose here is to make the identifiers shorter and less confusing. Unlike Hashids, Crockford Base32 does nothing to conceal the real value of the number (beyond the actual encoding, anyway) and the fact that they are sequential is still pretty obvious when you see consecutive identifiers side by side.

This library does not support encoding and decoding of arbitrary data. Additionally, the spec supports the idea of check digits, but this library currently does not.

The primary purpose of this library is to provide high performance, user-resistant encoding of numeric identifiers. To that end, both encoding and decoding are, in fact, pretty darn fast--an average of eight times faster than the most popular alternative on nuget.org. Additionally, no initialization is required; all methods are static. (And I mean static. There is no lazy initialization nonsense here!)

This library is a port of crockford for Rust.



Encoding is a one-step process.

var x = Base32.Encode(5111);
Assert.Equal("4ZQ", x);

If you want lowercase, then... Well, tough. However, we do now support encoding to a buffer of your choice rather than a new one created in the function. Read on to learn about plan B...

Alternate encoding

var buffer = new StringBuilder();
Base32.Encode(5111, buffer);
Assert.Equal("4ZQ", buffer.ToString());

...This will allow you to avoid additional allocations associated with creating a new stringbuilder on each call to Encode(). The call to ToString() is unavoidable.


Decoding is a two-step process. This is because you can feed any string to the decoder, and the decoder will return an error if you try to convince it that "Hello, world!" is a number. (Hint: it isn't.)

var x = Base32.Decode("4zq");
var y = Base32.Decode("4ZQ");

Assert.Equal(5111, x.Value);
Assert.Equal(5111, y.Value);

So, step one is to call the decode function. Step two is to match/verify/unwrap/throw away the output.
