ascii85

Utilities for working with ascii85 encoding.

Functions

f
decodeAscii85(
ascii85: string,
options?: Ascii85Options
): Uint8Array

Decodes a given ascii85-encoded string.

f
encodeAscii85(
data: ArrayBuffer | Uint8Array | string,
options?: Ascii85Options
): string

Converts data into an ascii58-encoded string.

Interfaces

I
Ascii85Options

Options for encodeAscii85 and decodeAscii85.

  • delimiter: boolean

    Whether to use a delimiter (if supported).

  • standard: Ascii85Standard

    Character set and delimiter (if supported and used).

Type Aliases

T
Ascii85Standard = "Adobe" | "btoa" | "RFC 1924" | "Z85"

Supported ascii85 standards for Ascii85Options.

base32

Utilities for base32 encoding and decoding.

Functions

f
decodeBase32(b32: string): Uint8Array

Decodes a base32-encoded string.

f
encodeBase32(data: ArrayBuffer | Uint8Array | string): string

Converts data to a base32-encoded string.

base58

Utilities for base58 encoding and decoding.

Functions

f
decodeBase58(b58: string): Uint8Array

Decodes a base58-encoded string.

f
encodeBase58(data: ArrayBuffer | Uint8Array | string): string

Converts data to a base58-encoded string.

base64

Utilities for base64 encoding and decoding.

Functions

f
decodeBase64(b64: string): Uint8Array

Decodes a base64-encoded string.

f
encodeBase64(data: ArrayBuffer | Uint8Array | string): string

Converts data into a base64-encoded string.

base64url

Utilities for base64url encoding and decoding.

Functions

f
decodeBase64Url(b64url: string): Uint8Array

Decodes a given base64url-encoded string.

f
encodeBase64Url(data: ArrayBuffer | Uint8Array | string): string

Convert data into a base64url-encoded string.

hex

Port of the Go encoding/hex library.

Examples

Example 1

import {
  decodeHex,
  encodeHex,
} from "@std/encoding/hex";

const binary = new TextEncoder().encode("abc");
const encoded = encodeHex(binary);
console.log(encoded);
// => "616263"

console.log(decodeHex(encoded));
// => Uint8Array(3) [ 97, 98, 99 ]

Functions

f
decodeHex(src: string): Uint8Array

Decodes the given hex-encoded string. If the input is malformed, an error is thrown.

f
encodeHex(src: string | Uint8Array | ArrayBuffer): string

Converts data into a hex-encoded string.

varint

Functions for encoding typed integers in array buffers.

Functions

f
decode(
buf: Uint8Array,
offset?
): [bigint, number]

Given a non empty buf, starting at offset (default: 0), begin decoding bytes as VarInt encoded bytes, for a maximum of 10 bytes (offset + 10). The returned tuple is of the decoded varint 32-bit number, and the new offset with which to continue decoding other data.

f
decode32(
buf: Uint8Array,
offset?
): [number, number]

Given a buf, starting at offset (default: 0), begin decoding bytes as VarInt encoded bytes, for a maximum of 5 bytes (offset + 5). The returned tuple is of the decoded varint 32-bit number, and the new offset with which to continue decoding other data.

f
encode(
num: bigint | number,
buf?: Uint8Array,
offset?
): [Uint8Array, number]

Takes unsigned number num and converts it into a VarInt encoded Uint8Array, returning a tuple consisting of a Uint8Array slice of the encoded VarInt, and an offset where the VarInt encoded bytes end within the Uint8Array.
