InstantHash is a free Chrome add-on developed by d3sk1ng that provides offline MD5 and SHA-1 encryption. With the ability to add other algorithms in the future, this extension offers a simple and convenient way to generate hash values for your strings.

One of the standout features of InstantHash is its offline functionality. It does not require an internet connection, ensuring that your data remains secure and private. Additionally, the extension guarantees that your string will not be saved on any server, further enhancing the privacy aspect.

Using InstantHash is incredibly easy. With a simple button located next to the address bar, you can generate MD5, SHA-1, SHA-256, and BASE-64 hashes of your strings. The extension automatically generates the hash without the need for any additional button presses.

Please note that InstantHash is currently in beta version, but it promises to introduce new functions in the near future. So if you're looking for a reliable offline encryption tool, InstantHash is definitely worth considering.
