Random base32 string generator for unique ID usage.

Package Exports

  • 7id

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (7id) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

7ID

Random base32 (RFC 4648 without padding) string generator for unique ID usage.

This library includes the function generate(), which accepts a number of bytes to be used by crypto on it's function randomBytes().

The proportion of characters generated and the length of bytes requested is 5/16 (0.3125). Each 5 bytes, 16 characters are generated. 10 bytes output is a string of 32 characters.

Collision probability

The probability depends on the bytes length informed.

On a practical test of collision, the genetions that colided was:
