+/**
+  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.
