Download Cryptographic ID on PC

Cryptographic ID is a Tools application developed by Simon Brand, but with the best Android emulator-LDPlayer, you can download and play Cryptographic ID on your computer.

Running Cryptographic ID on your computer allows you to browse clearly on a large screen, and controlling the application with a mouse and keyboard is much faster than using touchscreen, all while never having to worry about device battery issues.

With multi-instance and synchronization features, you can even run multiple applications and accounts on your PC.

And file sharing makes sharing images, videos, and files incredibly easy.

Download Cryptographic ID and run it on your PC. Enjoy the large screen and high-definition quality on your PC!

- Attest the state of a Linux computer

This app can verify signatures made with cryptographic-id-rs. When your computer is in a trustworthy state, you can generate a private key hidden in the TPM2 of your computer. This private key can be sealed with the current state of the computer (PCRs). Then the computer can only sign a message with this key when it is in the correct state according to the PCRs. For example, you can seal the key against the secure boot state (PCR7). If your computer is booting an operating system signed by another vendor, the TPM2 cannot unseal the private key. So if your computer can generate a correct signature, it is in this known state. This is similar to tpm2-totp but uses asymmetric cryptography. This means you do not need to keep the verification code a secret, but you can share it safely with the world.


- Verify the identity of a phone

You can generate a private key when your phone is in a trustworthy state. If your phone can create a correct signature, you know it is the same phone. Since the operating system can access the private key, the security guarantees are much weaker than with a TPM2. So the verification is just as secure as your phone. If you use Graphene OS, I recommend Auditor instead.


- Verify that a person is in possession of a private key

This works as the section above and has the same shortcomings. It can be used to verify someone in person when he sends his public key to you in advance.
