How Text Encryption / Decryption Works

This tool uses password-based encryption to turn readable text into an encoded ciphertext string that can be safely stored or shared. When you decrypt, the tool reverses the process by verifying the password and restoring the original plaintext. Under the hood, it relies on AES (Advanced Encryption Standard), a widely used symmetric encryption algorithm where the same secret (your password-derived key) is used for both encryption and decryption.

Step-by-Step

• 1) Paste your input: Add the text you want to protect (a message, token, configuration snippet, or notes).
• 2) Choose mode: Select Encrypt to generate ciphertext, or Decrypt to restore plaintext.
• 3) Set a password: Enter a strong password that you can remember or store in a password manager.
• 4) Pick a cipher: Use AES‑256 for maximum strength or AES‑128 for shorter keys and compatibility.
• 5) Generate output: The tool produces a single encoded string that includes everything needed to decrypt later (except the password).
• 6) Decrypt when needed: Paste the ciphertext, enter the same password, and the original text appears.

Key Features

AES Encryption Options

Select between AES‑256‑CBC and AES‑128‑CBC. AES‑256 is a strong default for most users, while AES‑128 is sometimes preferred for legacy compatibility. Both options use a unique initialization vector (IV) for each encryption to keep identical inputs from producing identical outputs.

Single-String Output

The encrypted result is returned as one compact string. The tool bundles the IV with the ciphertext so that you can safely store or transfer it without managing separate parameters.

URL-Safe Encoding

Need to place ciphertext in a URL parameter or filename? Enable URL‑safe output to avoid characters that require escaping. This is useful for quick sharing in links or system integrations.

Copy and Download Workflow

Copy encrypted or decrypted results with one click, or download the output as a plain TXT file for archiving. The interface is optimized for fast, repeatable workflows.

Privacy-Friendly by Design

The tool operates as a simple transformer: it takes your input, applies encryption or decryption, and returns output. For best security practices, treat your password as the secret and avoid reusing it across unrelated data.

Use Cases

• Sharing credentials securely: Encrypt a temporary password before sending it through chat, then share the password via a different channel.
• Protecting personal notes: Store private notes in a document or ticketing system in encrypted form.
• Securing API keys: Encrypt keys or tokens before saving them in drafts or internal wikis.
• Redacting sensitive fields: Replace confidential values in logs with ciphertext while keeping the ability to restore them later.
• Testing encryption workflows: Quickly validate how encryption, encoding, and transfer behave in your pipeline.
• URL-embedded payloads: Generate URL‑safe ciphertext for short payloads shared via links.

Whether you are a developer, marketer, freelancer, or IT admin, password-based encryption helps you reduce accidental exposure of confidential data while keeping access simple when you need it.

Optimization Tips

Use a Strong Password

Security depends heavily on password strength. Prefer a long passphrase (12–20+ characters) and store it in a password manager. If you share ciphertext with others, share the password through a separate channel.

Choose URL-Safe Only When Needed

Standard Base64 is the best default for storage and copy/paste. Switch to URL‑safe encoding when your ciphertext must travel through URLs, filenames, or systems that rewrite special characters.

Keep Cipher Settings Consistent

Decryption must use the same cipher option used during encryption. If you plan to reuse the tool for a workflow, standardize on one cipher (usually AES‑256) to avoid confusion.
