Uses PBKDF2 with 100,000 iterations for key derivation, AES-256-GCM for encryption, and cryptographically secure random salt/IV. All processing happens locally in your browser.
How to Encrypt Text Online
- 1
Enter your text
Type or paste the plaintext message you want to protect into the input field. The tool accepts any length of text including multi-line content, code snippets, and special characters. - 2
Set a strong password
Enter a password that will be used to derive the encryption key. Choose a strong passphrase of at least 12 characters, or click Generate Strong Password to create one automatically with our built-in generator. - 3
Encrypt your message
Click the Encrypt Text button. The tool uses PBKDF2 with 100,000 iterations to derive a 256-bit key from your password, then encrypts the text with AES-256-GCM. A unique salt and initialization vector are generated for each operation. - 4
Copy or download the result
The encrypted ciphertext appears in the output area. Copy it to your clipboard or download it as a file. Share the ciphertext freely since it is unreadable without the correct password. To decrypt later, paste the ciphertext and enter the same password.

Why Use Text Encryption?
The FindUtils Text Encryption Tool provides AES-256-GCM encryption entirely within your browser. AES-256 is the same symmetric encryption standard trusted by governments, banks, and security professionals worldwide. Every encryption operation generates a unique salt and initialization vector, so encrypting the same text with the same password produces different ciphertext each time. Your data never leaves your device because all cryptographic operations run locally through the Web Crypto API, the same engine that secures HTTPS connections.
The key derivation process uses PBKDF2 with 100,000 iterations, which transforms your password into a 256-bit encryption key resistant to brute-force and dictionary attacks. GCM mode adds authenticated encryption, meaning any tampering with the ciphertext is automatically detected during decryption. This combination of strong key derivation and authenticated encryption makes the tool suitable for protecting sensitive data such as passwords, API keys, legal documents, and private communications. For additional protection, pair this tool with a Password Generator to create truly random encryption passwords, or verify your password strength with the Password Strength Checker.
Unlike server-side encryption services that require you to trust a third party with your plaintext, client-side encryption keeps you in full control. There are no accounts to create, no data uploaded, and no usage limits. Whether you need to encrypt a single password or a multi-page document, the tool handles it instantly. For asymmetric encryption workflows where you need public and private key pairs, see the PGP Encryption Tool. To verify data integrity without encryption, explore our HMAC Generator or Hash Comparison Tool.
How It Compares
AES-256-GCM and PGP serve different encryption needs. AES-256 is symmetric: one password encrypts and decrypts. It is fast, simple, and ideal when you control both ends of the communication or are encrypting data for your own storage. PGP is asymmetric: it uses a public key to encrypt and a private key to decrypt, making it better for secure communication between parties who have never shared a secret. Our Text Encryption Tool uses AES-256-GCM for its speed and simplicity, while the PGP Encryption Tool is available when you need public-key cryptography.
Compared to online encryption services that process data on their servers, browser-based encryption eliminates the risk of data interception during transmission and removes the need to trust a third-party server. The trade-off is that you are fully responsible for managing your password: lose it, and the data is gone. For hashing rather than encryption, where you need a one-way fingerprint of data instead of reversible protection, our SHA-256 Hash Generator and MD5 Hash Generator are the right tools.
