Common

This repository houses many common algorithm implementations and data structures which can be dropped into larger projects, (any language is fine). They are designed to be general-purpose with a good focus on performance.

base64

Base64.encode(data, [byteOffset], [byteLength])

Returns a Uint8Array of character codes of the base64 string.

• data: An ArrayBuffer object
• byteOffset: An optional offset used as the start of the buffer (default: 0)
• byteLength: An optional length of data used to find the end (default: data.byteLength)

Base64.decode(array)

Returns a Uint8Array of the byte stream (should really be ArrayBuffer).

• array: Array of character codes of a base64 string (should really be a JavaScript string).

Data checksums

md5

MD5(data, [byteOffset], [byteLength])

Returns a computed hash of data as Uint8Array of 16 bytes

The arguments have the same meaning as listed above.

sha256

SHA256(data, [byteOffset], [byteLength])

Returns a computed hash of data as Uint8Array of 32 bytes

The arguments have the same meaning as listed above.

Encodings

UTF8.encode(string)

Returns an ArrayBuffer of the UTF8-encoded string

• string: A JavaScript string

UTF8.decode(...)

Not implemented!

spelling

Look at the end of the file spelling.js for an example usage with Node.js.
