New Revision: 3213
Modified:
trunk/payloads/libpayload/include/libpayload.h
Log:
Add BIN2HEX and HEX2BIN macros (trivial).
They're generally useful for lots of stuff, but especially for converting
to/from the compact 160 bit (20 byte) representation of SHA-1 hashes to
the "hex" representation (same as 'sha1sum' output), which is 40 bytes long.
