Encrypt Online
Encrypt text, strings, JSON, YAML, config files and more!
Use this encrypt online tool to encrypt text, strings, JSON, YAML, and config data directly in your browser. Choose an algorithm, enter a passphrase, and get an encrypted result in seconds.
- Select the encryption type (AES-256-CBC or 3DES).
- Paste the text you want to encrypt.
- Enter a passphrase to secure the data.
- Click "Encrypt" and copy the output on the right.
This tool supports AES-256-CBC and 3DES encryption.
Use the Decrypt Tool with the same passphrase.
You can encrypt any text value, including:
- Text
- Strings
- JSON
- YAML
- Config files
- Logs and API payloads
Use encryption to protect sensitive notes, credentials, and private links before sharing them.
Encryption converts readable data into ciphertext so only someone with the right key can recover it. It is a core security practice for protecting data at rest and in transit.
Use the Base64 Encode tool when you need text-safe encoding without encryption.
Does this tool store my data?
No. Encryption runs entirely in your browser and inputs are not stored on a server.
Which algorithms are supported?
AES-256-CBC and 3DES are supported on this page.
What do I need to decrypt later?
Use the same algorithm and passphrase with the Decrypt Tool.
