The Cuvex device uses AES 256 GCM encryption for the highest security, ensuring that your crypto seed phrase is encrypted and stored and is stored on a completely isolated Cuvex NFC card.

The device does not store any data after processing, and it does not connect to networks, the cloud, or any peripherals, ensuring your crypto seed storage remains private and secure at all times.

The AES 256 GCM encryption algorithm and hardware architecture guarantee the creation of a cryptogram of the highest quality.

The device does not store any information, all processes are performed without connection to any external device and without internet connection. Storage on an NFC card is already secure in itself, since only the stored cryptogram can be accessed, which is already encrypted before being stored on the card.

AES 256, is possibly the most secure encryption algorithm today. In some published studies, it is estimated that a current supercomputer could take more than 10,000 years to break an AES 256 cipher. This is the encryption algorithm used for military and government secrets.

Our code is public and anyone can audit what we say. Despite including the device, a secure hardware element where information is handled for each process, no data is ever stored in it. You only have to guarantee to remember your Passwords, if you forget this information, neither we nor anyone else can help you recover your secret.

Any card containing a Cuvex cryptogram can be decrypted using any Cuvex device, provided you have the passwords used during the encryption process. If you lose access to these passwords, neither we nor anyone else will be able to assist in decrypting your secret.

The AES-256-GCM algorithm, implemented via hardware, is a military-grade encryption standard widely used across public and private industries.

Yes, you can encrypt even plain text not linked to crypto assets.

With Cuvex you can encrypt any secret, private key or seed.
