Module to easily and possibly securily sign strings.
The goal is to avoid reinventing the wheel each time one needs to sign strings.
Usage to sign a string:
$signed = Pluf_Sign::sign($mystring); // send the string over the wire $mystring = Pluf_Sign::unsign($signed);
Usage to pack and sign an object:
$signed = Pluf_Sign::dumps($myobject); // send the string over the wire $myobject = Pluf_Sign::loads($signed);
Based on the work by Simon Willison: http://github.com/simonw/django-openid/blob/master/django_openid/signed.py
dumps( $obj, $key = null, $compress = false, $extra_key = '') : string
Dump and sign an object.
If you want to sign a small string, use directly the sign/unsign function as compression will not help and you will save the overhead of the serialize call.
| $obj | ||
| $key | ||
| $compress | ||
| $extra_key |
Signed string
sign( $value, $key = null) : string
Sign a string.
If the key is not provided, it will use the secret_key available in the configuration file.
The signature string is safe to use in URLs. So if the string to sign is too, you can use the signed string in URLs.
| $value | ||
| $key |
