What kind of encryption does SN use for credentials?

The correct choice identifies that ServiceNow (SN) utilizes 3DES (Triple Data Encryption Standard) for encrypting credentials. 3DES operates by applying the DES (Data Encryption Standard) cipher algorithm three times to each data block, significantly enhancing security beyond what the original DES could provide. This multi-layered approach ensures that encrypted data is more resistant to brute-force attacks, which is crucial for protecting sensitive credentials within the ServiceNow platform.

Other encryption methods mentioned, such as AES (Advanced Encryption Standard), RSA (Rivest–Shamir–Adleman), and Blowfish, have their own uses and strengths. AES is widely recognized for its efficiency and security in various applications, and RSA is a public-key encryption system favored for secure data transmission. Blowfish is known for its speed and effectiveness in encrypting data in smaller applications. However, in the context of ServiceNow's approach to credential encryption, 3DES is the specified standard in their security infrastructure as of the latest information available.
