Locktera uses cryptographic signatures to ensure the authenticity and integrity of your data. When you secure a container, Locktera applies a unique cryptographic signature that verifies its origin and confirms that it hasn’t been tampered with. This signature provides you with a secure way to authenticate data, assuring you that the information you’re handling is both genuine and unaltered. Cryptographic signatures also enable you to maintain a detailed audit trail, enhancing transparency and supporting compliance requirements. 

Cryptographic Signatures, also known as digital signatures, are a mechanism used to verify the authenticity, integrity, and non-repudiation of your secure Locktera containers. These signatures ensure that the secured container was sent by the claimed sender (authentication), that it hasn’t been altered in transit (integrity), and that the sender cannot deny sending the Locktera container (non-repudiation).

How Locktera Uses Cryptographic Signatures:

Signing:
You create a hash (a unique fixed-length string) of the secured container.
This hash is then encrypted using your private key to generate the digital signature.
The resulting signature is attached to the original Locktera container.

Verification:
The recipient decrypts the digital signature using your public key.
They hash the received container and compare it to the decrypted hash.
If the hashes match, the container is verified as authentic and unchanged.

Locktera leverages cryptographic signatures as a critical part of its encryption framework to ensure the authenticity, integrity, and non-repudiation of your data and communications. Here's how Locktera uses cryptographic signatures:

Authentication and Verification:
When you transmit or store containers, Locktera uses asymmetric encryption to generate a unique digital signature. The container owner creates a hash of the container and signs it with their private key. This ensures that the data originates from a trusted source and hasn’t been altered.

The authorized recipient can verify the authenticity of the data by decrypting the signature using the sender's public key. If the decrypted hash matches the hash of the received data, its integrity is confirmed.

Non-Repudiation:
By signing the container with your private key, Locktera ensures non-repudiation, meaning you cannot deny sending the data. This is essential in industries where accountability is critical, such as financial documents, legal agreements, or sensitive information .

Securing Communication:
For containers within the Locktera ecosystem, cryptographic signatures authenticate the parties involved, ensuring that data exchanged between users is both trusted and protected from tampering during transit.

By incorporating cryptographic signatures, Locktera enhances its security model, ensuring that the authenticity and integrity of your data are always maintained, while also providing accountability and transparency in your digital workflows.
