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:
