Welcome to the One Time Secret tool, a secure and convenient way to share sensitive information using one-time links. With this tool, you can encrypt your secret note or password and generate a unique link that can be accessed only once. This ensures that your confidential information remains secure and confidential, preventing unauthorized access after the link has been used. Whether you need to share passwords, access codes, or any other sensitive data, the One Time Link / One Time Secret tool has got you covered!

What is One Time Link (aka One Time Secret)?

  • If you ever need to send a password or a secret note with sensitive information to someone that you can not send it over email or chat, you can now use our One Time Link / One Time Secret tool to generate a one time link.
  • Sharing sensitive info via email or chat are not secure as anyone can intercept and store that information. Using our One Time Link / One Time Secret as the extra layer to safely and securely transfer the data to your recipients, just generate link and share online.

How it Works

  1. Enter Your Secret Note: Start by entering your confidential information or secret note into the provided textarea. This could be a password, a private message, or any sensitive information that you want to share securely.

  2. Set Optional Passphrase: For an added layer of security, you can optionally set a passphrase. This passphrase acts as an additional authentication factor, ensuring that only individuals who know the passphrase can access the secret information. You can either generate a random passphrase or enter your own.

  3. Choose Link Lifespan: Select the desired lifespan for the one-time link. After this period, the link will expire and become inaccessible. Choose a timeframe that suits your needs, balancing convenience with security.

  4. Generate One-Time Link: Click on the “Generate” button, and the tool will create a unique one-time link for your secret. This link can only be accessed once and is automatically destroyed after use, providing an extra layer of security.

  5. Share the Link: Copy the generated one-time link and share it with the intended recipient. You can communicate it through secure channels like encrypted messaging, email, or any other method you prefer. Remember to share the passphrase separately if you have set one.

  6. Accessing the Secret: When the recipient clicks on the one-time link, they will be directed to the secret content. If you have set a passphrase, they will need to enter it to decrypt and access the secret information. Once accessed, the link becomes invalid, ensuring that the secret remains confidential.

How secured is the stored note?

  • The secret note is encrypted in the browser prior to sending to our server to store AND encrypted again on server side prior to actual storage (i.e. 2-layer encryption), only available once to those you share the secret link with and only your secret link can decrypt the stored notes:
    • The notes are completely secured and even we can’t decrypt it.
    • Part of the encryption key is stored in the link itself and never seen by us or anyone else.
    • Viewing the secret note is not possible without the original link.
  • Once expired or viewed, the encrypted secret notes and passphrase will be deleted from our database forever (self destruct link), there’s no way to view it again^. This ensures nobody has opened it before the recipient and nobody can open it again afterwards. One-time link, always!

Key Features

  • One-Time Access: The one-time link ensures that the secret can only be accessed once, providing an extra layer of security and preventing unauthorized access to the confidential information.

  • Passphrase Protection: Optionally set a passphrase to further secure your secret. Only individuals with the correct passphrase can decrypt and access the confidential information.

  • Customizable Lifespan: Choose the lifespan of the one-time link, allowing you to control how long the secret remains accessible. After the specified timeframe, the link is automatically invalidated.

  • Easy Sharing: Copy the generated one-time link and share it with the intended recipient through your preferred communication channels. Remember to share the passphrase separately if applicable.

Security Recommendations

  • Only share your secret note or password, do not share or mention all other information together (eg: username, platform of the password, your organisation, etc.), which can compromise security. Instead, break them into multiple notes and share them separately if needed.
  • If you have set a passphrase, it’s recommended sending the one-time link and the passphrase via different mediums, eg: one-time link via email and passphrase via message, to maximise the security.
  • Use a strong and unique passphrase to maximize the security of your secret. Avoid common phrases, predictable combinations, or easily guessable information. Recommend using our Password Generator.

We adopt Advanced Encryption Standard (AES)

The Advanced Encryption Standard (AES), also known by its original name Rijndael, is a specification for the encryption of electronic data established by the U.S. National Institute of Standards and Technology (NIST) in 2001.

AES is a variant of the Rijndael block cipher developed by two Belgian cryptographers, Joan Daemen and Vincent Rijmen, who submitted a proposal to NIST during the AES selection process. Rijndael is a family of ciphers with different key and block sizes. For AES, NIST selected three members of the Rijndael family, each with a block size of 128 bits, but three different key lengths: 128, 192 and 256 bits.

AES has been adopted by the U.S. government. It supersedes the Data Encryption Standard (DES), which was published in 1977. The algorithm described by AES is a symmetric-key algorithm, meaning the same key is used for both encrypting and decrypting the data.

In the United States, AES was announced by the NIST as U.S. FIPS PUB 197 (FIPS 197) on November 26, 2001. This announcement followed a five-year standardization process in which fifteen competing designs were presented and evaluated, before the Rijndael cipher was selected as the most suitable (see Advanced Encryption Standard process for more details).

AES is included in the ISO/IEC 18033-3 standard. AES became effective as a U.S. federal government standard on May 26, 2002, after approval by the U.S. Secretary of Commerce. AES is available in many different encryption packages, and is the first (and only) publicly accessible cipher approved by the U.S. National Security Agency (NSA) for top secret information when used in an NSA approved cryptographic module (see Security of AES, below).
