Usage

hmac-signature -key="<a key>" -url="<url>" -nonce="<optional nonce>" -params="<param list>"

For example:

$ hmac-signature -key="key" -url="example.com/path" -nonce="123" -params="c=3 b=2 a=1"
URL: example.com/path
Params: a=1&b=2&c=3

Nonce: 123

if the nonce is not provided, one is generated automatically:

$ hmac-signature -key="key" -url="example.com/path" -params="c=3 b=2 a=1"
URL: example.com/path
Params: a=1&b=2&c=3
Nonce: 1427897981316727363
Data: 1427897981316727363example.com/patha=1&b=2&c=3
