Where is the Recovery Public Key usually stored?

The Recovery Public Key is typically stored in a Hardware Security Module (HSM). HSMs are specialized hardware devices that provide secure generation, storage, and management of cryptographic keys. They are designed to protect sensitive information by controlling access to cryptographic operations and keys, ensuring that even if other systems are compromised, the keys remain secure.

Using an HSM for storing the Recovery Public Key is advantageous because it offers a high level of physical and logical security, safeguarding keys against unauthorized access and operational tampering. HSMs also provide a secure environment for performing cryptographic functions without exposing the keys to software environments that may be less secure.

In contrast, storing the Recovery Public Key in a digital vault, physical safe, or local machines could introduce vulnerabilities. Digital vaults, while secure, may not have the same level of protection as HSMs specifically designed for cryptographic key management. Physical safes are prone to physical theft and may not be accessible for automated processes. Local machines can be particularly risky, as they are often exposed to a range of cybersecurity threats, increasing the chances of unauthorized access or malware attacks.
