buf-b32 v2.2.0

buf-b32

Converts a buffer holding binary to base32 (buf_b32 or encode); and converts a buffer or base32 string into a buffer (b32_buf or decode).

Uses loads of bitwise notation. Have fun?

2.0.0 update

only returns Uint8Arrays now.

converting a Uint8Array to a Buffer: Buffer.from(u.buffer, u.byteOffset, u.byteLength).

All internal values use Uint8Array now.

Docs

encode(buffer, useString)

• buffer: ArrayBufferView (Buffer, Uint8Array, Uint32Array, DataView etc)
• useString: boolean
• Returns: string | Uint8Array

When useString is true, returns string; else returns Uint8Array.

decode(buffer, overwrite)

• buffer: ArrayBufferView (Buffer, Uint8Array, Uint32Array, DataView etc)
• overwrite: boolean
• Returns: Uint8Array
