generate a signature for an object
require('sig') returns a function which takes any type of object, and returns
a signature string, generated from the sha1 of the
stable JSON representation.
Optionally you can pass an encoding as the second parameter, which can be
var sig = ;console;// 2491cd3eb77052427bfa91dfd6fb2824c5022ecaconsole;// 07043187e80e6cf42d238b0f40fef9b68bb08242console;// BwQxh+gObPQtI4sPQP75touwgkI=console;// <SlowBuffer 07 04 31 87 e8 0e 6c f4 2d 23 8b 0f 40 fe f9 b6 8b b0 82 42>
The old version (0.x) of
sig used a CRC32 implementation which was a
bad idea and was also about 5x
slower than the newer, crypto-based solution. If you upgrade, be aware that
the 1.x signatures are longer, hex-based (although other encodings can be generated)
and not backwards-compatible with 0.x signatures.
