 		A better solution is to properly configure the firewall,

+- Hashing support:
+		CONFIG_CMD_HASH
+
+		This enables a generic 'hash' command which can produce
+		hashes / digests from a few algorithms (e.g. SHA1, SHA256).
+
+		CONFIG_HASH_VERIFY
+
+		Enable the hash verify command (hash -v). This adds to code
+		size a little.
+
+		CONFIG_SHA1 - support SHA1 hashing
+		CONFIG_SHA256 - support SHA256 hashing
+
+		Note: There is also a sha1sum command, which should perhaps
+		be deprecated in favour of 'hash sha1'.
