Override only when Auto cannot parse your paste. Changing this loads a matching sample into Input — click Convert to run. Use Load sample to cycle every format example.

All conversions

Read-only representations of the same 16 bytes. Every textual form is listed here, not in “Prefer format”.

Paste two values: if both sides are valid JSON, a structural diff appears; otherwise UUID / bytes are compared when both decode to the same format.

A
B

Create or edit JSON here (syntax colors), then format, validate, or convert - same as MongoDB $binary UUID blobs on the Convert tab once detected.

New document

Hash, HMAC, AES-GCM/CBC + RSA-OAEP, codecs, JWT decoding, UUID v4, and secure random - all client-side. JWTs use Base64URL (three segments), not a single MIME Base64 block - use Decode JWT below, not raw Base64 decode.

About SHA-256 Hash

SHA-256 is the workhorse checksum of modern software - Git object IDs, TLS certificate fingerprints, package integrity hashes, blockchain blocks. If you need a quick, verifiable digest of some text, this is almost always the right algorithm.

Computed with the browser's native SubtleCrypto digest API and rendered as lowercase hex. It's a general-purpose hash, not a password hash - for storing user credentials, use bcrypt or Argon2 instead, which are deliberately slow.

FAQ

Is this for passwords?
Use dedicated password hashing (Argon2, bcrypt). SHA-256 alone is not password storage.
