function base58_to_binary

converts a base58 to its corresponding binary representation Uint8Array

Parameter	Type	Description
base58String	base58_chars	base58 encoded string

Returns: Uint8Array — binary representation for the base58 string

Examples

base58 to binary

import { base58_to_binary } from '@relocke/base58'

const bin = base58_to_binary("6MRy")
console.log(bin) // Uint8Array(3) [15, 239, 64]
Buffer.from(bin).toString('hex') // 0fef40

---

function binary_to_base58

Converts a Uint8Array into a base58 string

Parameter	Type	Description
uint8array	Uint8Array | Array	unsigned integer array

Returns: base58_chars — base58 string representation from the binary array

Examples

Binary array to base58 string

import { binary_to_base58 } from '@relocke/base58'

const str = binary_to_base58([15, 239, 64])
console.log(str) // 6MRy
