Question 1

Are the generated UUIDs, ULIDs, and API keys cryptographically secure?

Accepted Answer

Yes. All identifiers are generated using the browser's native Web Crypto API (crypto.getRandomValues() and crypto.randomUUID()), which draws high-entropy randomness directly from your operating system's cryptographic random source.

Question 2

What is the difference between UUID v4, UUID v7, and ULID?

Accepted Answer

UUID v4 is completely random. UUID v7 (RFC 9562) and ULID (Universally Unique Lexicographically Sortable Identifier) combine a 48-bit millisecond timestamp with random bits, making them chronologically sortable and preventing database B-tree index fragmentation. ULID formats as a 26-character Crockford Base32 string, while UUID v7 formats as a 36-character hyphenated hexadecimal string.

Question 3

Why use NanoID instead of standard UUID?

Accepted Answer

NanoID is more compact (21 characters vs 36 characters) and URL-safe without punctuation hyphens, while providing equivalent collision resistance for web applications and public resource identifiers.

Question 4

Can Ambiakshi see or log the generated API keys?

Accepted Answer

No. Because the generation occurs 100% client-side in your browser's local JavaScript execution context, no generated keys or tokens are ever sent to our servers.

Question 5

How should I store generated API keys in a database?

Accepted Answer

Treat API keys like passwords: store only a cryptographic hash (such as SHA-256 or Argon2) of the key in your database, displaying the raw key to the user only once upon creation.
