UUID V4
128 bits, 16 bytes
122 bits of entropy, 5.31691198 × 1036 possible IDs
“...the odds of collision between any two is 1 in 2.71 x 1018 Put another way, one would need to generate 1 billion v4 UUIDs per second for 85 years to have a 50% chance of a single collision.”

OLC IDs
12 characters, 12 bytes
51.863 bits of entropy, 4.096 × 1015 possible IDs
Open Location Code (OLC) alphabet Ids. OLC is a geocoding system that encodes latitude and longitude into a short string of characters. The alphabet is simplified to use only uppercase letters and digits, excluding characters that can be easily confused (like '0' and 'O', '1' and 'I').

Encrypted URL IDs (GUID)
Base64URL encoded encrypted V7 UUID tokens. Each token packs an 8-byte random IV plus a UUIDv7 XOR-masked with an HMAC-SHA256 keystream derived from the IV and a private key, so the token is opaque and non-sequential in URLs but still reversible to recover the original UUIDv7 (and its embedded timestamp) server-side.
