How does it work EviCore NFC HSM Browser Extension?

The EviCore NFC HSM Browser Extension works with an NFC HSM device that contactless stores your secrets in a secure way. You can create different types of secrets, such as login IDs, credit cards, notes, seed phrases, identification cards or cloud keys. Each secret has a label that identifies it and allows you to find it easily.

To use a secret, you need to scan a QR code to pair your NFC HSM device with your phone. Then, you need to connect your phone to your computer via a local or ad-hoc network encrypted from end to end with one-time keys generated by certificates renewed at each session by exchanging 5 public keys between the extension and the application. This makes it impossible for a man-in-the-middle attack.

Once connected, you can access and use your secrets from the extension for various purposes. For example, you can encrypt or decrypt data using your phone as a terminal to the NFC HSM. You can also auto-fill or auto-login to websites using your secrets without having to know, enter, memorize, see or access them. The multi-factor authentication is done by the Android NFC application with EviCore NFC HSM technology that automatically verifies all authentication factors defined by the user of NFC HSM.

The extension also offers other features that enhance your online security and convenience. For example, you can generate strong passwords or QR codes with a click of a button. You can also check if a website uses https or http protocol and if its domain name extension is prone to typosquatting attacks.

Auto-filling of cryptocurrency information

The EviCore NFC HSM Browser Extension also offers a unique feature for cryptocurrency users: the contactless auto-filling of private keys, public addresses and seed phrases from the NFC HSM device. This feature allows you to fill in any field of any platform that accepts the import of cryptocurrency information without having to know, enter, memorize, see or access them.

To use this feature, you need to create a label (secret) in your NFC HSM device that contains your private key, public address or seed phrase. You can choose from various formats and standards, such as BIP 39. You can also select the number of words and the language for your seed phrase.

Once you have created your label, you can use it to auto-fill any field on any website that supports cryptocurrency import. For example, you can use it to access your wallet, exchange or platform without having to type or copy your information. The extension will automatically detect the type and format of the field and fill it with the corresponding information from your label.

This feature is very convenient and secure for cryptocurrency users who want to avoid typing errors, clipboard hacking and phishing attacks. It also contactless saves you time and hassle by simplifying your access to your cryptocurrency accounts.

However, this feature does not allow you to sign transaction operations on the blockchain. The extension does not have access to your secrets and cannot perform any action on your behalf. You still need to use another tool or device to sign and confirm your transactions.

The contactless auto-filling of cryptocurrency information is a unique feature that distinguishes our extension from other solutions on the market. It is designed to offer you more security and convenience for your online activities involving cryptocurrencies.

Pwned

Enhanced cyber security function (Free): “Pwned” provides proactive monitoring for your online credentials. By leveraging a database of compromised usernames and passwords, the extension automatically performs a secure check when you enter your login information. This analysis, conducted via hashing, scans multiple data breach incidents to determine if your email address or phone number has been compromised. With this free tool at your disposal, you can anticipate and prevent identity theft by safeguarding your personal information. The role of the “Pwned” extension goes beyond detection. Not only does it identify compromised usernames and passwords, but it also keeps you informed in case any of your passwords are compromised. Armed with this information, you can take prompt action and change any compromised credentials.
