Cryptographic Entropy & Identifier Architecture
High-entropy pseudo-random number generation (CSPRNG) utilizing the browser W3C Web Cryptography API.
UUID v4 provides 122 bits of pure cryptographic entropy. UUID v7 encodes a 48-bit millisecond Unix timestamp followed by 74 bits of entropy for B-Tree index optimization.
ULIDs pack 48-bit timestamp and 80-bit randomness into Crockford Base32 strings (26 characters), delivering monotonic sorting and case-insensitive portability.
Generated keys never traverse the network. Generated identifiers reside strictly in your client device's V8 execution context.
FREQUENTLY ASKED QUESTIONS
Q: What is the probability of a UUID collision?
With 122 bits of entropy in UUID v4, generating 1 billion UUIDs every second for 85 years yields less than a 50% probability of a single collision.
Q: Why use UUID v7 over UUID v4 in databases?
UUID v7 starts with a time prefix, preventing index page fragmentation in PostgreSQL and MySQL databases while preserving universal uniqueness.
