You plan to store passwords in a Windows Azure SQL Database database.
You need to ensure that the passwords are stored in the database by using a hash algorithm, Which cryptographic algorithm should you use?
A. ECDSA
B. RSA-768
C. AES-256
D. SHA-256
yes, maybe:
Hashing (also known as hash functions) in cryptography is a process of mapping a binary string of an arbitrary length to a small binary string of a fixed length, known as a hash value, a hash code, or a hash. Hash functions are a common way to protect secure sensitive data such as passwords and digital signatures. Some of the modern commonly-used hash functions are MD5, RIPEMD160, SHA1, SHA256, SHA384, and SHA512.
Hashing is a one-way conversion. You cannot un-hash hashed data.
