_section: Encoding Utilities

_subsection: Base58

_property: ethers.utils.base58.decode(textData) => Uin8Array
Return a typed Uint8Array representation of //textData// decoded using
base-58 encoding.

_property: ethers.utils.base58.encode(aBytesLike) => string
Return //aBytesLike// encoded as a string using the base-58 encoding.


_subsection: Base64

_property: ethers.utils.base64.decode(textData) => Uin8Array
Return a typed Uint8Array representation of //textData// decoded using
base-64 encoding.

_property: ethers.utils.base64.encode(aBytesLike) => string
Return //aBytesLike// encoded as a string using the base-64 encoding.


_subsection: Recursive-Length Prefix

The [[link-rlp]] encoding is used throughout Ethereum to serialize nested
structures of Arrays and data.

_property: ethers.utils.RLP.encode(dataObject) => string<[[datahexstring]]>
Encode a structured Data Object into its RLP-encoded representation.

Each Data component may be an valid [[byteslike]].

_property: ethers.utils.RLP.decode(aBytesLike) => [DataObject](rlp-dataobject)
Decode an RLP-encoded //aBytesLike// into its structured Data Object.

All Data components will be returned as a [[datahexstring]].

_heading: Data Object @<rlp-dataobject>

A **Data Object** is a recursive structure which is used to serialize many
internal structures in Ethereum. Each **Data Object** can either be:

- Binary Data
- An Array of **Data Objects** (i.e. this recursively includes Nesting)

_definition: **Examples**

- ``"0x1234"``
- ``[ "0x1234", [ "0xdead", "0xbeef" ], [ ] ]``
