Encrypt & Decrypt Cipher Studio | TsudioTech

Tool Purpose & Context

The Crypto Vault on TsudioTech.com is a browser-based tool for encrypting and decrypting text. It is designed to make basic text encryption easy to use without requiring special software, command-line tools, or complicated key management.

It can be useful for everything from hiding a spoiler to protecting a sensitive note before storing or sharing it.

Casual and Fun Uses

• Hide movie, TV, or game spoilers in forums and group chats.

• Create clues for ARGs, treasure hunts, and puzzle games.

• Send playful encoded messages to friends.

Practical Uses

• Obscure temporary API keys or other short-lived credentials.

• Share a Wi-Fi password through a channel you don't fully trust.

• Encode personal notes before putting them into an unencrypted document or cloud draft.

The tool performs its encryption and decryption directly in your browser. Your message and passphrase do not need to be sent to a TsudioTech server.

For genuinely sensitive information, use a strong passphrase and share that passphrase through a separate, trusted channel. Browser-based encryption is useful, but it should not be treated as a replacement for a properly managed secure communication system.

Step-by-Step Usage Guide

Encrypting a Message

1. Select Encrypt Mode
   Make sure the mode is set to Encrypt.

2. Enter Your Message
   Type or paste the text you want to protect into the input field.

3. Choose an Algorithm
   Select one of the available options:

   • AES-256-GCM: The recommended choice for sensitive information.

   • Enigma Cyber-Rotor: A classic rotor-style cipher intended primarily for experimentation and fun.

   • Stealth Vigenère: A lightweight substitution-style option for simple encoding.

   • Random: Lets the tool choose one of the available algorithms for you.

4. Enter a Passphrase
   Choose a strong passphrase. Anyone decrypting the message will need the same passphrase.

5. Encrypt the Message
   Click Encrypt to generate the encrypted output.

6. Copy or Share the Result
   Copy the generated TSUDIO-VAULT-v1 ciphertext, or use the share-link option to create a URL containing the encrypted payload.

Decrypting a Message

1. Select Decrypt Mode
   Set the tool to Decrypt, or open a shared #payload= link if you have one.

2. Paste the Encrypted Message
   Paste the ciphertext into the input field. A normal encrypted payload begins with:

   TSUDIO-VAULT-v1:

3. Enter the Passphrase
   Enter the same passphrase that was used when the message was encrypted.

4. Decrypt the Message
   Click Decrypt. If the passphrase and encrypted data are correct, the original message will appear in the output area.

How the TSUDIO-VAULT-v1 Format Works

The tool wraps encrypted messages in a standard envelope called TSUDIO-VAULT-v1.

The envelope contains information the tool needs to interpret the encrypted payload, including the selected algorithm and format version.

This makes sharing and decryption easier in a couple of ways.

Automatic Algorithm Detection

You don't have to remember which algorithm was used when the message was encrypted.

The encrypted envelope contains the necessary algorithm information, so the tool can identify the correct method when you decrypt it.

This is particularly useful when using Random mode.

Shareable Links

The encrypted payload can also be placed inside the URL's hash fragment using a format such as:

#payload=...

When someone opens the generated link, the tool can read the payload and prepare it for decryption. They still need the correct passphrase to access the original message.

Keep in mind that anyone who has the link can see the encrypted payload. The passphrase should therefore be shared separately.

Practical Use Cases

For anything genuinely sensitive, AES-256-GCM should be preferred over the more playful cipher options.

Frequently Asked Questions

Is my message or passphrase sent to a central server?

No. The tool is designed to perform encryption and decryption locally in your browser using JavaScript.

Your plaintext and passphrase do not need to be uploaded to the TsudioTech server.

What happens if I forget my passphrase?

There is no password-reset or recovery system for an encrypted message.

If you lose the passphrase, the encrypted message may be impossible to decrypt. Make sure you keep your passphrase somewhere safe or share it with the intended recipient through a separate trusted channel.

Do I need to select the same algorithm when decrypting?

No, as long as the encrypted message uses the TSUDIO-VAULT-v1 format.

The envelope contains the algorithm information needed by the tool, so it can determine which method to use during decryption. You still need the correct passphrase.

Can I share an encrypted message using a web link?

Yes. The share-link feature places the encrypted payload inside the URL fragment.

When the recipient opens the link, the Crypto Vault can automatically load the encrypted message and prepare it for decryption.

The passphrase is not a substitute for the link, so share it separately. Anyone who obtains the link can still see the encrypted payload, even though they cannot decrypt it without the correct passphrase.
