Base32 is a binary-to-text encoding scheme that represents binary data in an ASCII string format by translating the data into a radix-32 representation. Each non-final Base32 digit represents exactly 5 bits of data. Five 8-bit bytes (i.e., a total of 40 bits) can therefore be represented by eight 5-bit Base32 digits; this is known as a block. RFC4648 compliant encoding requires that the resultant string be a full block, so "remainder blocks" are padded with '=' characters.
See: https://tools.ietf.org/html/rfc4648#section-6
This project is based on the Base64 component that is included in the Standard Pony Library.
use "Base32"
actor Main
new create(env: Env) =>
env.out.print(Base32.encode("foobar"))
try
env.out.print(Base32.decode[String iso]("MZXW6YTBOI======")?)
end- An error is raised during decoding if the string is not a valid Base32 encoded string.
- The library does not currently support the Base32Hex alphabet.
Corral Instructions:
$ corral add github.com/tj800x/pony-base32.git
$ corral run -- ponycRunning the project executable will execute the tests, which should look something like this:
