SCRU160: Sortable, Clock and Random number-based Unique identifier
SCRU160 ID is yet another attempt to supersede UUID in the use cases that need decentralized, globally unique time-ordered identifiers. SCRU160 is inspired by ULID and KSUID and has the following features:
- 160-bit feature-rich worry-free design suitable for general purposes
- Sortable by generation time (in binary and in text)
- Case-insensitive, highly portable encodings: 32-char base32hex and 40-char hex
- More than 32,000 unique, time-ordered but unpredictable IDs per millisecond
- Nearly 111-bit randomness for collision resistance
import { scru160, scru160f } from "scru160";
console.log(scru160()); // e.g. "05TTUP1HNCPNH30VEK64KDQT9BSNU4C4"
console.log(scru160()); // e.g. "05TTUP1HNCPNIB63R8IN5V2L3VFGNFET"
console.log(scru160f()); // e.g. "017bdf6431bb33750751eb63beb3c3f8c5969d86"
console.log(scru160f()); // e.g. "017bdf6431bb337662412e6a5758890735c33c2b"See the specification for further details.
