- 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) ========
