How are credentials decrypted on the MID Server?

Credentials on the MID Server are decrypted using the Web Service key. This key plays a crucial role in secure communication, ensuring that sensitive information, such as credentials, is protected during transmission and when stored.

When the MID Server receives encrypted credentials, it utilizes the Web Service key to decrypt them, allowing safe access to the required resources and services necessary for discovery operations. This process helps maintain a secure environment while enabling the functionalities within ServiceNow, such as system discovery and integration with various IT assets.

The other options do not apply in this context because the user password is not used for decryption by the MID Server, and there is no specific "administrator key" utilized for this purpose either. The notion that credentials can be decrypted automatically without keys is also incorrect, as all decryption processes depend on specific keys to maintain security and confidentiality.
