### About Tiger

* Tiger cryptographic hash function is designed by Ross Anderson and Eli Biham in 1995.
* The size of a Tiger hash value is 192 bits. Truncated versions (Tiger/128, Tiger/160) are simply prefixes of Tiger/192.
* Tiger2 is a variant where the message is padded by first appending a byte 0x80, rather than 0x01 as in the case of Tiger.

### API Documentation

Implementing [hash.Hash](http://golang.org/pkg/hash/#Hash). Usage is pretty much the same as other stanard hashing libraries.
