Text Encrypt/Decrypt
Encrypt and decrypt your text using AES encryption. Your passphrase stays in the browser. Nothing is sent to a server.
Why FileReadyNow
Encrypt and Decrypt Text with a Passphrase in Your Browser
Enter your text and a secret key, encrypt it instantly, and share or store the output knowing it cannot be read without the key.
Strong Encryption
Uses AES encryption with your chosen passphrase to produce ciphertext that cannot be reversed without the correct key.
Two-Way Operation
Encrypt any plaintext message or decrypt any ciphertext back to the original using the same passphrase and tool.
Fully Client-Side
Encryption and decryption happen entirely in your browser. Your text and passphrase are never sent to any server.
One-Click Copy
Copy the encrypted or decrypted output to your clipboard instantly and paste it wherever you need it.
Works with Any Text
Handles messages, notes, credentials, code snippets, and any other plain text content without length restrictions.
No Account Required
Open the tool, enter your text and passphrase, and encrypt or decrypt. No login, no tracking, no usage limits.
There are times when you need to protect a piece of text before sharing or storing it, whether it is a password, a private note, a sensitive credential, or confidential information. The Text Encrypt and Decrypt tool from FileReadyNow uses AES encryption with a passphrase you provide to scramble your text into an unreadable cipher. Only someone with the same passphrase can reverse the process and recover the original content. Everything runs in your browser so your text never leaves your device.
What This Tool Does
The tool uses AES (Advanced Encryption Standard), a widely trusted and industry-standard encryption algorithm, combined with a salt and initialization vector to produce secure, unique encrypted output even for the same input encrypted multiple times. The encrypted text is encoded in Base64 for easy copying and sharing as plain text. To decrypt, paste the encrypted output and enter the same passphrase to recover the original message.
How It Works
- Enter the text you want to protect in the input field
- Provide a passphrase that will be used as the encryption key
- Click Encrypt to produce an AES-encrypted, Base64-encoded output
- To decrypt, paste the encrypted text, enter the same passphrase, and click Decrypt
The passphrase is never stored or transmitted. If the passphrase is lost, the encrypted text cannot be recovered.
Common Use Cases
- Sharing Sensitive Information: Encrypt a password, PIN, or private note before sending it over email or a messaging app, then share the passphrase separately.
- Storing Credentials Temporarily: Encrypt a credential or token before saving it in a text file or note so it is not stored in plain text.
- Developer Testing: Test encryption and decryption behavior in an application by using this tool to verify that AES-encrypted values match expected outputs.
- Personal Notes Security: Encrypt personal journal entries or private notes before storing them somewhere accessible to others.
What to Keep in Mind
The strength of the encryption depends directly on the strength of your passphrase. A weak or common passphrase makes the encrypted text much easier to break. Use a long, unique passphrase for maximum security. This tool is suitable for personal and light-duty use. For enterprise-level security requirements or regulatory compliance needs, consult a qualified security professional and use dedicated encryption infrastructure rather than a browser-based tool.
Step by Step
How to Use the Text Encrypt/Decrypt Tool
Encrypting Text
In the Secure Text field, input the text you wish to encrypt.
In the Secure Pin field, enter a passphrase that will be used as the encryption key.
Click Encrypt Data to generate the encrypted text, which will appear in the Encrypted Key field.
Use the Copy Key button to copy the encrypted text for storage or sharing.
Decrypting Text
Switch to the Decrypt Text tab and paste the encrypted text into the Encrypted Key field.
In the Secure Pin field, enter the same passphrase used during encryption.
Click Decrypt Data to reveal the original text in the Secure Text field.
Use the Copy button to copy the decrypted text as needed.
Frequently Asked Questions
It’s an online tool that allows you to securely encrypt and decrypt text messages in seconds, no installation required.
Simply enter your text, choose “Encrypt,” and the tool will generate a secure encrypted version instantly.
Yes, as long as you have the correct encrypted text and the shared method or key used to encrypt it.
Absolutely. The tool works locally in your browser, meaning your text isn’t stored or shared online.
No, it’s completely free and runs directly on the web at FileReadyNow.
