/**
Derives a key from a password using a salt and iteration count, based on PKCS#5 v2.0
password based encryption key derivation function PBKDF2, as specified in RFC 2898.
If Password or Salt or OutKey is NULL, then return FALSE.
If the hash algorithm could not be determined, then return FALSE.
@param[in] PasswordLength Length of input password in bytes.
@param[in] Password Pointer to the array for the password.
@param[in] SaltLength Size of the Salt in bytes.
@param[in] Salt Pointer to the Salt.
@param[in] IterationCount Number of iterations to perform. Its value should be
greater than or equal to 1.
@param[in] DigestSize Size of the message digest to be used (eg. SHA256_DIGEST_SIZE).
NOTE: DigestSize will be used to determine the hash algorithm.
Only SHA1_DIGEST_SIZE or SHA256_DIGEST_SIZE is supported.
@param[in] KeyLength Size of the derived key buffer in bytes.
@param[out] OutKey Pointer to the output derived key buffer.
@retval TRUE A key was derived successfully.
@retval FALSE One of the pointers was NULL or one of the sizes was too large.
@retval FALSE The hash algorithm could not be determined from the digest size.
@retval FALSE The key derivation operation failed.
