What does the Basic Auth Generator create?

It converts a username and password into an HTTP Basic Authorization header and provides matching curl and fetch examples.

Is Basic Authentication encryption?

No. Basic Authentication only Base64-encodes the username and password, so the credentials must be sent over HTTPS to protect them in transit.

Does it support non-English usernames and passwords?

Yes. Its UTF-8-aware encoding handles non-ASCII characters more reliably than a basic byte-limited encoder.

No. The username, password, and generated header remain in your browser.

HTTP Basic Auth vs Bearer Tokens: Which Should You Use?

A practical comparison of HTTP Basic Authentication and Bearer/JWT tokens — how each works, their trade-offs, and when to reach for which.

AES Encryption

Encrypt and decrypt text with AES-GCM and a passphrase, fully in your browser. Uses PBKDF2 key derivation and the Web Crypto API — your data and keys never leave your device.

Bcrypt Generator & Verifier

Hash passwords with bcrypt and verify hashes — choose your cost factor (rounds 4–15), get a secure hash instantly, and check whether a password matches a hash. Runs entirely in your browser.
