Which encryption method does ServiceNow use to store credentials in the Discover_credential table?

The encryption method used by ServiceNow to store credentials in the Discover_credential table is AES Encryption. This method is widely recognized for its strength and efficiency in safeguarding sensitive information such as credentials. AES (Advanced Encryption Standard) is a symmetric encryption algorithm that offers a high level of security and performance, making it suitable for web applications and cloud-based services like ServiceNow.

AES encryption works by using the same key for both encryption and decryption, which means that only individuals or systems with the correct key can access the stored credentials. This approach significantly enhances security compared to other methods that may not provide symmetric protection or that are less robust.

In contrast to other options provided, RSA encryption is generally used for asymmetric encryption tasks such as key exchange, while 3 DES (Triple Data Encryption Standard) is considered outdated and less secure compared to AES. On the other hand, SHA256 Hashing is a hashing algorithm, not encryption, meaning it is suitable for scenarios where data must not be retrieved in its original form but is not meant for storage of credentials.
