Which algorithms are used to secure REST API from brute attacks and minimize the impact?

1. A. SHA-512 and SHA-384
2. B. MD5 algorithm-128 and SHA-384
3. C. SHA-1, SHA-256, and SHA-512
4. D. PBKDF2, BCrypt, and SCrypt

Correct Answer: D
One of the best practices to secure REST APIs is using password hash.
Passwords must always be hashed to protect the system (or minimize the damage) even if it is compromised in some hacking attempts. There are many such hashing algorithms which can prove really effective for password security e.g. PBKDF2, bcrypt and scrypt algorithms.
Other ways to secure REST APIs are: Always use HTTPS, Never expose information on URLs
(Usernames, passwords, session tokens, and API keys should not appear in the URL), Adding Timestamp in Request, Using OAuth, Input Parameter Validation.
