_section: Encoding Utilities @<encoding>

_subsection: Base58 @<Bse58> @SRC<basex: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 @<Base64>

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

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


_subsection: Recursive-Length Prefix @<rlp--methods>

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

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

Each Data component may be a valid [[BytesLike]].

_property: ethers.utils.RLP.decode(aBytesLike) => [DataObject](rlp--dataobject)  @<utils.rlpDecode> @SRC<rlp>
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" ], [ ] ]``
