Text Encrypt / Decrypt
Encrypt and decrypt text with a password using AES-256-GCM in your browser. Share the encrypted string safely; only the right password can read it. Nothing is uploaded.
AES-256-GCM · PBKDF2-SHA256 · 100k iterations · salt+IV prepended
| Algorithm | Key | KDF | Used here | Notes |
|---|---|---|---|---|
| AES-256-GCM | 256-bit | PBKDF2-SHA256 100k | Yes | Authenticated encryption — tampering detected on decrypt |
| AES-256-CBC | 256-bit | PBKDF2 | — | Legacy; needs separate HMAC for integrity |
| ChaCha20-Poly1305 | 256-bit | PBKDF2 / Argon2 | — | Modern AEAD; common on mobile TLS stacks |
| XChaCha20-Poly1305 | 256-bit | Argon2id | — | Extended nonce — safer for random IV reuse |

FAQ
What can I use Text Encrypt / Decrypt for?
Text Encrypt / Decrypt is useful when you need to encrypt and decrypt text with a password using AES-256-GCM in your browser. Share the encrypted string safely; only the right password can read it. Nothing is uploaded. It is meant for quick checks, everyday workflows and practical tasks where a fast browser-based result is enough.
How do I use Text Encrypt / Decrypt correctly?
Paste or type the value exactly as you want it checked. Remove accidental spaces unless the tool says spaces are accepted.
What input does Text Encrypt / Decrypt need?
Use the fields shown in the tool and keep the input close to the real case you want to solve. If the page includes examples or presets, start with those to understand the expected format.
What result does Text Encrypt / Decrypt give me?
The tool returns a local validation, generated value, decoded data or explanation of why the input passes or fails. In most cases the output updates instantly and can be copied, downloaded or used as a reference for your next step.
How accurate is Text Encrypt / Decrypt?
A valid-looking result usually confirms format, checksum or local generation logic only. It does not prove that an account, card, token or identity is real.
Is my data uploaded when I use Text Encrypt / Decrypt?
The tool is designed to run in your browser, so ordinary inputs are processed locally unless a page explicitly states that it needs an online lookup.
What common mistakes should I avoid with Text Encrypt / Decrypt?
Check units, spelling, separators, dates, decimal points and empty fields before trusting the result.
What related tasks can Text Encrypt / Decrypt help with?
Text Encrypt / Decrypt is intended for use cases related to "text encrypt" and nearby needs such as "encrypt text". For best results, follow the labels, examples and options on the page.
What are the limits of Text Encrypt / Decrypt?
It is optimized for common web use, not unlimited batch processing or every edge case.
When should I double-check the output from Text Encrypt / Decrypt?
Double-check the output before relying on it for access control, compliance, payments, identity checks or production security.
