Encode and validate an Ethereum address againstEIP-55 checksum in Elixir.

The package can be installed by adding:eip_55 to your list of dependencies inmix.exs:

defpdepsdo[{:eip_55,"~> 0.1"}]end

Encoding:

iex>EIP55.encode("0x5aaeb6053f3e94c9b9a09f33669435e7ef1beaed"){:ok,"0x5aAeb6053F3E94C9b9A09f33669435E7Ef1BeAed"}iex>EIP55.encode(<<90,174,182,5,63,62,148,201,185,160,...>159,51,102,148,53,231,239,27,234,237>>){:ok,"0x5aAeb6053F3E94C9b9A09f33669435E7Ef1BeAed"}

Validation:

iex>EIP55.valid?("0x5aAeb6053F3E94C9b9A09f33669435E7Ef1BeAed")trueiex>EIP55.valid?("0x5AAEB6053f3e94c9b9a09f33669435e7ef1beaed")false

This library uses:ex_sha3 which is a pure Elixir implementation making itsignificantly slower than an NIF-based library like:sha3.

If you have a demand for high-performance EIP-55 encoding/validation, let me know.Maybe we can then add a NIF-based version.
