+	100% free public domain implementation of the SHA-1 algorithm
+	by Dominik Reichl <dominik.reichl@t-online.de>
+
+	Version 1.5 - 2005-01-01
+	- 64-bit compiler compatibility added
+	- Made variable wiping optional (define SHA1_WIPE_VARIABLES)
+	- Removed unnecessary variable initializations
+	- ROL32 improvement for the Microsoft compiler (using _rotl)
+
+	======== Test Vectors (from FIPS PUB 180-1) ========
