The purpose of this integration is to enhance the security of GnuPG-based cryptographic operations by leveraging the u.trust GP HSM as a secure key storage and processing platform. By offloading sensitive cryptographic functions to the HSM, private keys and certificates are protected within a tamper-resistant environment, reducing the risk of key exposure and unauthorized access. This ensures that critical operations such as encryption, decryption, digital signing, and verification are performed in a secure and controlled manner.
