Q. When Hashing(SHA-256) is used for storing the user created question and answer - is it simple hashed or anything else is used to make it more secure.
A. Both hashed and encrypted. Hashing is done either using MD5 or SHA256 (depends on user selection). Encryption uses a pre-defined salt to encrypt and uses Rijndael algorithm
